This site will serve as my FAA required builders log, a fun way to track my journey, and a source for others who come behind me.

The next step is to align the canard properly so the mounting holes can be located and drilled. This involved matching the center-line (C/L) of the canard to the C/L of the front bulkhead...which if I've done everything correct so far should actually be the C/L of the airplane. Wouldn't that be great!<br>

<b>It's All Gotta Balance</b><br>
<br>
The last part of the canard/elevator build is to install the mass balance weights. Control surfaces have to balance properly to avoid flutter. Airplane...and especially pilots, don't like flutter! Here's how we prevent it.<br>

With the elevators in place, the canard can now get tips to finish out the ends. The plans version have a swoop up at the ends that some people don't really like. A simpler version just rounds off the tips to blend directly into the airfoil. Unless you do something really weird, it's really about aesthetics here and not aerodynamics. I think the plans tips give it a little character so I kept to the plans here.<br>

</tbody></table>
The elevators are built and assembled into one piece and now they have to be hinged to the canard. Jigs are attached to the bottom of the canard and then the elevators are inserted into the back side of jig which forces them into a trailing edge (TE) high position of 15 degrees. This is supposed to be the amount of throw you want to have in the down (TE up) position.<br />
<div>
<br /></div>
<div>
Mine were very tight inserting into the jig...so much that a jig popped off from the canard and I had to re-attach it. Looking it over, it appeared that the TE of the canard was binding with the elevator making it too tight. I decided to sand a bit on the TE for to give some space. Had I looked ahead in the plans just a bit, I would have seen that it tells you that you may need to sand a bit <u>underneath</u> the TE to obtain the 15 degree travel. Not seeing this yet, I sanded the back edge of the TE making it a bit shorter in chord...like .1 inch. I wasn't too concerned about this sanding at the time because I thought there was supposed to be a gap of .2" between the top of the elevator and the canard TE according to the picture in the plans.<br />

Fortunately, curiosity got the best of me and I did some research in the archives. Here I found a reference to the "NEW" jigs and notes in the plans that talked about how the new jigs didn't leave a gap at all. I had missed those notes as they weren't in the text but under one of the figures. Oh my...did I sand too far? I wasn't sure so I asked Marc Z. about it. He assured me that... <i>"<span style="background-color: white; color: #222222; font-family: "arial" , "helvetica" , sans-serif; font-size: x-small;">If the shape of the slot is correct, the hinge point is in the right place, the Glass to Glass bond on the TE is 0.5" or more, and you can get 15 deg. of up elevator, you should be fine."</span></i>...and in fact I have all those things. Any more sanding though and I would have messed up the .5" glass-to-glass bond on the TE. Good thing I had put in some margin.<br />
<br />
Whew...that was close. As it turns out...spoiler alert...when checked after the hinging was completed, I was getting exactly 15 degrees. I could have gotten it without loosing the fractional chord length, but all's well that ends well.<br />

With everything jigged and in proper position I could now locate and dig out the hinge slots. This went pretty well using a Dremel tool and a routing bit. You just have to be careful not to penetrate the glass on the other side of the canard as the hinges go almost all the way. The plans have you install the hinges in the torque tube, fill the slot with flox 2/3 way, and rotate the hinge into the slot to cure. I found that I couldn't rotate the hinges into the slots because the slots would need to be long enough to require digging out some of the spar cap. I wasn't going to touch the spar cap so I just reversed the order and dropped the hinges into the slot first, then put the hinge pin through the torque tube to precisely locate them. Worked just fine.<br />
<br />
<br />
After the hinges cured, I broke off all the jigs so everything was free to move. The elevators were smooth as silk and had all the required travel.</div>

This section is all mechanical, no glass work here.<br />
<br />
<br />
<b>Close-Out the Outboard Ends</b><br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgstuaNWw-ayGDrl9GpMc_JxSoovqkIKdu8vtUrgkySr4pjTNrbn0HtH3eLP3cfx0_EfMwHjXNJbYVgMqCaeHmPxAPWK6O31T7oreCZZZw2_GzW2SYYZ3gWoeLqjYCF3UcTOywmX3NN/s1600/IMG_20200427_143433.jpg" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1135" data-original-width="1600" height="226" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgstuaNWw-ayGDrl9GpMc_JxSoovqkIKdu8vtUrgkySr4pjTNrbn0HtH3eLP3cfx0_EfMwHjXNJbYVgMqCaeHmPxAPWK6O31T7oreCZZZw2_GzW2SYYZ3gWoeLqjYCF3UcTOywmX3NN/s320/IMG_20200427_143433.jpg" width="320" /></a>The first task was to clean out the outboard ends of each elevator torque tube and install the NC-6 insert end pieces to cap them off. In doing so, I had to drill two holes, one for a rivet (in front in the picture) that holds the NC-6 in place, and the other on the bottom where a small threaded lock screw will eventually lock in the stainless hinge pin. The bottom one was a little nerve racking because your drilling blind into an already threaded hole. Missing the hole would be bad and blowing through the torque tube and into the threads would screw them up. <i><b>TIP:</b></i> I did this work in a serial manner...install rivet, then figure out the blind hole to drill. What I should have done was use the rivet to hold the part in place (but not permanently squeezing it in) while I located the blind hold to drill. Then removed the part, drilled the hole, and then permanently installed the part with the rivet. That would have eliminated the risk of ruining threads in the part. Oh well, this is an educational activity after all! I'll probably be saying that a lot.<br />
<br />
I did my best to measure the location of the hole using a digital caliber and transferring the location onto the outside of the torque tube. I was dead on the first time. On the second I was close enough but I think I ate up a few threads in the insert. There are clearly some still there so all is good.<br />
<br />
<b>Uh Oh...Questioning the Dimensions</b><br />
Now I laid all the parts out on the bench end-to-end to make sure everything was looking correct before I started drilling holes. I compared the hinge locations in the hardware to the hard points embedded in the canard and noticed that the first inboard hinge points were not falling quite in the middle of the hard point at B.L. 15.6" per plans. It was only off by .1" at 15.7" and would work fine, but it shouldn't have been off at all...what was up?<br />
<div style="text-align: right;">
</div>
<br />
I did multiple measurements of all the parts and hard point locations and what I found was that the <br />
Cozy Girls CZNC-12A offset torque tube dimensions were slightly longer than the plans on the inboard side of the hinge slot which made the overall length of the part .2" longer than the plans indicate. So it that was the case, why weren't my elevators .2" longer on each side? Something had to be wrong in the plans. Additionally, only the first hinge slot is off and by only .1". It falls at B.L. 15.7" vs the plans 15.6". The outer two hinge locations were per plans and when I measure the overall length of the elevator assembled on the bench it comes to 140.8" just as it should be. What's going on here? The only answer I could come up with was that are multiple places in the plans dimensions for the offset torque tube as well as hinge hard point locations in the canard that must be incorrect.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjDODvFwgg8hMlWDqy9Kjbigs0ltyy5xWigvjBxTsbztizlRitT2EHGDj9wUU-kXve7g8WI1vpAU127UYf_Wvs_dFx6JjiqazK3l45VmDlRYpOJhTPDg9uB18EEUlSRjZyE9Ad9b5S/s1600/CZNC-12A+Dimensions.png" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="1128" data-original-width="1340" height="269" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjDODvFwgg8hMlWDqy9Kjbigs0ltyy5xWigvjBxTsbztizlRitT2EHGDj9wUU-kXve7g8WI1vpAU127UYf_Wvs_dFx6JjiqazK3l45VmDlRYpOJhTPDg9uB18EEUlSRjZyE9Ad9b5S/s320/CZNC-12A+Dimensions.png" width="320" /></a>I spent way to long on this for a .1" difference but I wanted to understand what was going on. Here is what I found. I already mentioned the CZNC-12A being .2" longer than plans spec. Additionally, I believe the B.L 15.6" callout for the location of the center of the first inboard hinge hardpoint and hinge slot in the CZNC-12A is wrong in the plans (Ch 10 pg 7, fig 48, and Ch 11 pg 2). I know this because if you starting from the center line and add up the length of the center torque tube (15.1") and the length of the plans dimensions for the CZNC-12A up to the center of the inboard hinge slot(.265" +.110"), you find the location of the center of the inboard hinge should be 15.475" or 15.5" rounded up instead of 15.6" per plans. Now, when you use the Cozy Girls .2" longer CZNC-12A, it places the hinge slot at B.L. 15.7", .1" outside the plans incorrect 15.6" callout but .2" outside the calculated location based on the plans .2" shorter CZNC-12A dimension. The other two hinge slots in the elevators are correctly called out and work perfectly with the Cozy Girls part.<br />
<br />
Ok...what's the bottom line? My conclusion is that the plans .265" dimension inboard of the hinge slot in the CZNC-12A, Chpt 11 pg 2, is incorrect and should be .465" like the Cozy Girls version of the part. And, the callouts of the B.L. location of the inboard most hinge hard point and the matching CZNC-12A hinge slot, Ch 10 pg 7, fig 48 and Ch 11 pg 2, are incorrect and should be B.L. 15.7" instead of 15.6". Fortunately there is enough margin in the location of the 1" wide hinge hard points to account for this slight difference. So if you built it to plans, and used the Cozy Girl parts, all is still good. If however you built your own CZNC-12A to the plans dimensions, your elevator length is likely .2" too short on each side and none of the hinge hard point centers will match the torque tube hinge slots correctly. I remember in Chapter 10, when laying out the hard point locations, it recommended laying out the elevator torque tubes to check the hinge locations. This would have been smart to do.<br />
<br />
I'm guessing that sometime way back the Cozy Girls knew to correct for this in order to make the overall length work out correctly and that the plans somehow didn't get these dimensions updated. I don't know for sure. Searching the <a href="https://groups.google.com/forum/#!searchin/cozy_builders/cznc-12a%7Csort:date" target="_blank">archives</a> (which BTW I usually do before starting a chapter and didn't) revealed that others found the same anomaly with the offset torque tube but nobody seems to know exactly why. Reported discussions with the Cozy Girls also showed they apparently don't remember why the dimension was different. There is no mention of the hard point location possibly being incorrect. Some builders adjusted the length of the center torque tube to compensate. Others didn't, but it seems to me that if you do that you'll end up with slightly shorter elevators and will have to sand your canard slightly shorter to obtain the .1" elevator-to-canard tip gap. I'll go back and put a link to this discussion on my canard build page so future builders will at least be aware of this and can adjust the inboard hardpoint slightly should they so chose. A bigger issue is that anyone building their own CZNC-12A needs to know the plans dimensions are incorrect.<br />

</tbody></table>
Now that I decided everything was ok, it was time to start drilling holes to assembly all torque tube pieces that tie the two elevators together. This was simple enough...it's just 4 bolt holes that have to be drilled, but you have to do it in a way that ensures everything is aligned properly.<br />
<br />
----------------------------<br />
<b>TIP:</b> <i>Let me say that you want to be careful drilling holes in any control mechanisms. You can easily accidentally drill them slightly over-sized and over time they could develop slop...not something you want in your control system. Some builders use taper pins, which are great, but expensive. Some experts on the forum suggest that there's really only one place that makes sense for taper pins and that's the rudder torque tube assembly because of the amount of torque involved when applying the brakes. This is probably what I'll do. For the rest of the control system I'll stick with the plans bolts and if they give me any problem later I can always switch to taper pins. I doubt that will be the case.</i><br />
<i><br /></i>
<i>So, to ensure I didn't over-drill a hole, I started with a pilot hole per plans and then stepped up to the final size a little at a time. I stepped up 5 numbered drill sizes at a time and stopped with a drill that was 2 numbered drill sizes smaller than the bolt. Then I used a <a href="https://www.aircraftspruce.com/catalog/topages/bd50012.php" target="_blank">reamer</a> for the finish size making sure the reamer matched the actual bolt being used. This resulted in a nice tight fit.</i><br />
<i><br /></i>
<i>Get yourself a set of numbered drill bits, 1 thru 60. I got mine from Drill Hog on Ebay and they have a lifetime warranty. Break one, send it back, get another.</i><br />

The first two bolt holes are the ones that connect the left and right offset torque tubes (CZNC-12A) to the "spool" piece (center torque tube). You can see that in the pic above. Using the process in the tip above this was straight forward and when done aligns the two offset torque tubes together.<br />
<br />
The next two attach the elevator torque tubes to the other side of the offset torque tube. This requires aligning the entire elevator assembly, bondo'ing it to the work bench, and dialing the center spool piece to the same position where the hinge pin will insert properly.<br />

There was actually a wide margin where I could rotate the center torque tube assembly and still insert the torque tube so I did my best to match the clocking of the hinge pin hole inside with that of the elevators and marked it on the outside to get it as close as I could.<br />
<br />
The only thing left to do is auger out the inboard foam to allow installation of the back side washer and nut on the torque tube bolt. The augered out foam will get filled in later after the inboard side of the elevators get trimmed to match the fuselage sides.<br />

After re-jigging the canard and turning it over, it was time to set about prepping it for the top spar and skin. I removed the fishtail per plans and began to remove the 1" strip of peel ply laid at the trailing edge. This proved to be extremely difficult and time consuming! The peel ply did not want to be removed.<br />
<br />
If that wasn't bad enough, it was difficult to tell when the peel ply was fully removed and there was only glass remaining. See a tip on the previous post about a possible way to prevent this. Perhaps a different peel ply would work better.<br />

Next I cut and installed the more dense foam (6 lb / cubic ft) used for the hinge hard points. I marked the locations and used a Dremel tool to auger out the foam. The plans were a little vague on the fore/aft location of the hinge hard point foam. I settled on a position about 1/4" below the spar cap down to about 1.3" from the trailing edge.<br />

When pulling off the peel ply you pretty much destroy the foam just in front of the clean trailing edge. Since this would have been foam anyway, I went ahead and filled the area with micro and created a smooth transition from the contour to the trailing edge. I reserved .6" of clean trailing edge glass for the glass-to-glass bond (hash marks). The FAQs say to leave no less than .5". After skinning I"m sure this area will need some additional external micro to bring the full contour back to where it's supposed to be.<br />

Since I laid up the bottom spar, Aircraft Spruce has starting sourcing their spar tape from an Australian company named Colan. Marc Zeitlin checked it out and gave it a rave review. I ordered this new tape for the top spar. I was able to get 13 plys of spar tape into the top spar trough compared to 12 on the 1st canard. This took me ~9 hrs working alone. Below are the layer lengths I was able to get.<br />
<u><br /></u>
<u>Layer</u> <u>Length each side of center</u><br />
1 62.5<br />
2 62.5<br />
3 62.5 <br />
4 58.5 <br />
5 56.5 <br />
6 50.5 <br />
7 50.5<br />
8 46.5<br />
9 44.5<br />
10 34.5<br />
<div style="text-align: right;">
</div>
11 30.5<br />
12 28.5<br />
13 18.5<br />
<br />
A total of 33.7 yards of spar tape was used on the top spar cap. All total I used 53.3 yards of spar tape for the 2nd canard...about 3.5 more than the 1st canard. Not a significant difference however my technique was better and I tried do a better job this time of not overfilling the contour too much and having to sand. Although I still had a few small high spots to sand, it was very minor compared to the 1st canard and thus I'm very happy with canard #2. I suspect my first canard may have been perfectly fine, but I didn't want that unsure feeling on such a critical part. I'll call the 1st canard the "practice" canard...although it was an expensive way to practice.<br />
<br />
<i><b>TIP: </b>The plans call for ordering 42 total yards of spar tape so buy extra spar tape! You don't want to be in the middle of a spar layup and run out.</i><br />

Skinning the top went according to plans with no issues. The only added complexity here is that you have to be sure to end each ply in a different spot around the leading edge to properly taper into the bottom and not leave a bump.<br />

These are not in the glass itself but mostly just on top of the glass, between fibers, just under a thin coat of epoxy left by the peel ply. They are a result of a poor peel ply job done after ~9 hrs of spar cap layup...I was tired. After confirming this with the experts in the forum, I was happy that this was no issue and has no impact on the finished product.<br />
<br />
<br />
At long last, this completes Chapter 10. If you've been noticing the dates on these posts don't interpret those as having anything to do with how long this work took. 1st, sometimes it takes me a while to write a post for something I did a while back. 2nd, I've had numerous breaks in building over the years as normal life and priorities get in the way. I will say though that I did have some trepidation in getting those spar caps done again which caused me to procrastinate a while. I now have some momentum and hope to keep that up.<br />
<br />
I can finally move on to the ups and downs of the elevators.<br />

Like the canard, I built my elevators with foam cores from <a href="http://www.eurekacnc.com/Home.htm" target="_blank">Eureka CNC</a>. They are perfectly shaped to contour and makes the job so much easier.<br />

I did have one problem... Eureka packed my canard jigs in the same box with the elevators and they were so tightly packed against the elevator cores that they ended up causing some impressions in the core foam. You can see the impression in the pictures at the right.<br />
<br />
Normally this wouldn't be a big deal but balancing elevators and ailerons is difficult and I'll have to add micro fill to fix this which means unnecessary extra weight. You have to use a minimum of micro, resin, etc. when making these control surfaces for them to balance properly. It becomes that much harder when you have to do any micro contour filling like this. I did contact Eureka and Steve offered to send me a section of elevator to replace the damaged section if needed. In this case however, I think it will work out. You can see that when the end is trimmed to the end of the torque tube, much of the problem is eliminated. Added to that, since I made sure to place the damaged area on the inboard side, it will be further trimmed to an angle to match the fuselage so about 80% of the damaged area will probably end up being cut off after it's all said and done.<br />

First up is installing the hinge mechanisms into the torque tubes. This went pretty much to plans but I would offer a few Tips.<br />
<br />
1st, I've probably said this before but I purchase all the hardware I can from the <a href="http://www.cozygirrrl.com/aircraftparts.htm" target="_blank">Cozy Girrls</a>. Their workwomanship is first rate! I like to build but I don't like it so much that I'm willing to manufacture my own metal parts.<br />
<br />
2nd, it wasn't obvious to me in the plans which direction the NC-2 inserts are installed into the torque tubes...hinge pin hole up or down? I didn't think any of the drawings made it perfectly clear. The best picture was Figure 4 where you can see that the hinge pin hole is at the bottom of the insert relative to the interior flat portion and with the elevator upright.<br />
<br />
3rd, before you secure the inserts with rivets, place the hinge pin through the NC-2 inserts. This will help ensure they are aligned and help you end up with fewer problems getting the hinge pin in and out later.<br />
<br />
And lastly, there have been some questions about which side of the NC-2 inserts do the torque tubes get the notch filed. The archives have different answers, the most recent being that the drawing on Ch. 11 pg 2 is incorrect in showing dotted (hidden) lines for the notches (indicating the notches are only filed on the bottom side of the torque tubes) and that both sides should be filed. When you go to mount the elevator with the NC-7 jigs, you realize the top (side furthest from the hinge pin hole) must be filed for that jig to work correctly. <span style="color: red;">The bottom side, doesn't end up needing to be filed at all to obtain full movement of the elevator.</span><br />

Glassing the elevators is pretty straight forward however you need to do your best work getting all the excess epoxy out of the layup. This will help you be able to balance them. I wet out my glass on a sheet of plastic and leave the plastic on when applying to the part. Leaving the plastic on makes it easy to eliminate air and squeeze out as much extra resin as possible. I then remove the plastic and apply peel ply which soaks up more of the excess...more than I would have thought it would.<br />

Tip: Leave the trailing edge glass a bit long so you have room to cut and sand it to the correct length before the top skin is applied.<br />

<br />
Before glassing the top skin, the plans have you remove some foam at the trailing edge, layup the top skin, trowel micro in the void left on top of the glass-to-glass trailing edge and then leave to cure. I did everything in the same order however I let the top skin cure before applying the micro at the trailing edge. I had a slight twist in the aileron and wanted to weight down the trailing edge nice and flat while it cured. I couldn't do that if the trailing edge was wet with micro...so I simply performed that step after the top glass cured and I had trimmed the trailing edge to the proper length.<br />

<b>Installation of the Leading Edges...</b><br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhxaZYVK0YqODofKaDL8a_3G4iQQX9axY6mLG1xmHgBp3NBx7b5p0sP3lJfJLOkPmytQ48a4xBlvkiV8KlnlJWgC1cpMCEG8BdCJeYDwL5hBjALTSCVC3lgGElV27VavUL2qaqteBYM/s1600/20190106_153733+%25232+2.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="900" data-original-width="1600" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhxaZYVK0YqODofKaDL8a_3G4iQQX9axY6mLG1xmHgBp3NBx7b5p0sP3lJfJLOkPmytQ48a4xBlvkiV8KlnlJWgC1cpMCEG8BdCJeYDwL5hBjALTSCVC3lgGElV27VavUL2qaqteBYM/s320/20190106_153733+%25232+2.jpg" width="320" /></a>Re-assembling the leading edges back on to the cores went per plans with no issues. The Eureka cores make it easy because they already have the alignment holes ready for the dowel rods to be inserted. The only thing I'll say you need to watch is to be sure you don't get the micro too thick between the leading edges and the face of the spar web because doing so can result in you still getting the leading edge slightly tilted up or down despite the alignment dowels.<br />
<br />
<b>Jigging the canard for the bottom spar...</b><br />
As mentioned earlier, I bought the Eureka canard jig templates...highly recommended. After attaching the templates, the leading edges, and the outer core sections, the only thing left was to make sure the canard was straight and not twisted.<br />
<br />
To check twist, I used a ~4" wide flat aluminum plate as a base for my digital level and placed it across the spar trough at multiple places across the full length of the canard. I only noted .5 degree differences across the full length. Small variations in the foam or the slightest misalignment where the cores connect can cause slight angle differences. It's hard to be perfect.<br />
<br />
To check straightness, I used a length of fishing line pulled tight between two clamps. I aligned it with various parts of the canard, like the bottom edge of the fishtail, the tangent point of the leading edge, etc. to determine if it was straight.<br />
<br />
<br />
<b>6, 9, 11 plys?</b><br />
There always seems to be questions about how many plys of spar tape you should use when building the spar. The Cozy archives have reports from 6 to 11 and more in either the top or bottom canard spars. The best answer to this I found was a mathematical discussion that used the thickness of a properly cut center canard core, the thickness of a ply of spar tape, the theoretical thickness of spar web, and the plans callout for 42 yards of spar tape to arrive at a theoretical "correct" number of plys. The math indicated 6 on the bottom and 9 on the top spar were correct...or in terms of yards of tape, 18yds on the bottom and 24 yds on the top. Don't take my word for this, do your own research. In any case, recommendations are always to fill up the trough without overfilling...but if you find you can only get 5 plys of spar tape in the bottom spar, it might be time to check your process and see why.<br />
<br />
<b>Spar...again...</b><br />
With the canard in place and aligned, it was time for the bottom spar layup. This was my 2nd canard build up and I don't mind saying I was more than a little nervous about doing this spar work again. So much so that it took me many months to finally do it. Rebuilding the canard isn't a cheap decision, but it was the right thing to do for such a critical part. I don't want to have to do it again.<br />

There was an additional complication this time. I purchased new spar tape from Aircraft Spruce and it was made just after they had months of downtime with the Rube Goldberg machine that makes the stuff. See this <a href="https://www.dropbox.com/sh/qf3mu2yfa2rtpsy/AAAlGkaoiT_3VrL3qz3EJCa8a?dl=0" target="_blank">link</a> if you want to see it in action. The tape wasn't as wide, 2.7" vs 3.0", which wasn't a big deal, but it also didn't have as many bundles of glass in it...25 vs 30 compared to some older tape I compared it with. To check, I cut 21" of both old and new tape, pulled the key thread and cross threads, and weighed each. Both samples weighed in within 1g of each other giving me confidence that although there were fewer bundles of glass, there was basically the same amount in each sample.<br />

<b>Bottom Skin</b><br />
After cure I checked the contour and had to do some minor sanding...nothing serious. With that I started prepping for the bottom skin. The skin layup was uneventful. This time, rather than wetting up the glass directly on the canard, I wet all the glass out on the table, on plastic sheet, first, then transferred the plys one at a time to the canard. I think that worked out better and perhaps may have been quicker.<br />

<b><i>Tip:</i></b> One thing I think I would do different is that I would try to place a layer of box tape under the peel play at the trailing edge. After flipping the canard, you'll have to pull the peel ply off...and it took hours to get it off. It only came off in small pieces and was hard to tell if I had gotten it all or not. Using some tape beneath it I think would have acted like a release layer and made the job of removing it take only minutes vs hours.<br />
<br />
Ok...time to flip it over.<br />

<b><br /></b>
I was not satisfied with my first canard build. I overfilled the spar cap with plans to sand it down to meet the contour, however I had to sand much more on the top spar than I planned and I started to question if I had sanded too much, broken too many fibers mid-span, etc. I think it's probably just fine, but rather than always have that question in my mind, I decided to rebuild this most critical part of the airplane...but now with improved skills.<br />
<br />
The next few posts are the original canard build posts but edited where needed to reflect the 2nd canard build. Many of the pics and description are still the same...I just did it better.<br />
<b><br /></b>
<b>To Hot Wire or Not to Hot Wire...</b><br />
I decided not to hot wire my own cores for the canard...and likely won't for the wings either. Since <a href="http://www.eurekacnc.com/Home.htm" target="_blank">Eureka CNC</a> does such a great job at a reasonable price, I figured why mess with trying to get the cores correct and the templates shaped perfectly for such important pieces. I would have ordered the entire canard/wing package deal but I didn't have anywhere to store the wing cores until I was able to start building them.<br />

The cores were perfectly cut and assembled easily. I built the 2x4 canard jig per the plans. The FAQs on the Cozy page discuss using 12" 2x4s for this, and you certainly can, but 10" works just fine. You'll have approx 1' hanging off of each end but it's not enough to create any problems.<br />
<br />
If you're wondering about the thin ply underneath the jig...I glued the 2x4s to this thin ply rather than the table top so that I could move it if needed.<br />

To ensure the 3 cores all aligned, I tied fishing line to clamps at each end of the canard and pulled it tight like a guitar string. Then by aligning it close, but not touching the cores, I could easily tell if there were any alignment issues I needed to deal with. <i><b>On the 1st canard, I failed to make sure the cores were aligned straight up and down in the jig. if they aren't, later you'll end up with angled lift tabs that you'll have to correct.</b></i> Make sure they are straight now...lengthwise, vertical with no twist between cores. Take your time here...it will pay off.<br />

They are very nice, already abraded and ready to install hardware. If I haven't said it, I highly recommend the hardware available from the <a href="http://www.cozygirrrl.com/aircraftparts.htm" target="_blank">CG Products</a>.<br />
<br />
Be sure to clearly mark the nut plate jig as to the direction it goes and whether it's left/right or port/starboard or whatever. You'll re-use these to drill the bolt holes through the glass once the shear web hard points cure.<br />

After installing the nut plates, glassing of the shear web went per plans with few issues. I recommend using good masking tape to tape off the portions of the cores below the spar trough. I used a mediocre duct tape which didn't stick very well and allowed epoxy to leak below the tapeline causing me some clean up work later to ensure the airfoil contour was not disturbed. Gorilla duct tape and the like is too sticky I think...might pull foam out when you remove it.<br />

Next, the leading edge was reinstalled per plans, and the canard was set in the template K jig blocks and aligned nice and straight. PS...I also purchased the canard jigs from Eureka CNC and highly recommend those as well. You just don't get better than 10 identical CNC machined jigs. I had spent time building a very flat bench where I used two 30" solid core doors as the bench top. The top was flat to within .1% of my digital level. I felt that as long as the top was flat, there should be no reason to have to shim anything unless the canard was twisted when the cores were assembled. If so, this is the time to shim if needed to set it straight. Time for the bottom spar cap.<br />

<b><br /></b>
The last thing to do is close-out the top of the MLG area. The plans have you leave two small diameter holes for inspection access to the MLG. Since I routed the brake lines on top of the MLG, I needed slightly bigger holes to ensure I could get to the brake lines if needed.<br />
<br />

So, rather than the plans round inspection holes, I built rectangular holes to give me more room. I also wanted to build access hole covers to help muffle any noise coming from there. With these, I can access any of the adel clamps holding the brake lines if I needed.<br />
<br />
After following the plans to glass one side of the PVC foam, cut it to shape, and fit the pieces to the MLG bulkhead area, I traced rectangular panels symetrically on the port and starboard side of the horizontal panel. <br />

These covers were then cut out with an angle inward from the top such that they would be self supporting when laid in place. The top and side panels were then floxed in place in the fuselage.

After cure, I popped them lose and trimmed the edges of the covers to approx 1/2" wide and cleaned up the excess micro. I think the only thing I'll do to secure them is maybe use a dab of clear silicone sealent in a few spots. That should keep them in place with no rattles. In theory, I'll only need to remove them every once in a while to inspect the top of the gear or brake lines.<br />

For this step, I'm only running the brake lines from the calipers, up the strut, and through the fwd MLG bulkhead. At that point I'll cap them off and wait until a later chapter to run the lines up to the front where the resevoirs and master cylinders will be.<br />
<br />
I chose to use SS braided PFTE lines (purchased from Pegasus Racing) from the calipers and up the strut because of the flexibility and movement of the MLG bow. Once through the Fwd MLG bulkhead, I'll convert to lighter weight AL tubing to run to the nose where I'll probably convert back to SS braided to the resevoirs.<br />

<br />
The angle at the caliper end was such that I chose a <a href="http://www.aircraftspruce.com/catalog/hapages/an823.php" target="_blank">45 degree angle NPT/AN fitting</a> and ran the line directly to the connection. With the direct connection I didn't feel I needed to include a service loop in the brake line as I have some slack I can pull from up between the bulkheads if needed. Don't forget to use a bit of pipe sealant seal on the NPT end...NOT on the AN ends. I used <a href="http://www.aircraftspruce.com/catalog/hapages/an823.php" target="_blank">Permatex thread sealant</a> that you can get at most local auto supply stores.<br />

<b>Routing Challenges:</b> My challenge was where to run and mount the braided line in the gear-well. It needs to be run in a way so it won't chafe on any structure, and doesn't get in the way of my main gear cover. I first ran it below the gear bow to a connection at the fwd bulkhead, and then planned to convert to AL tubing and complete the run to bulkhead connectors. This would give me easy access to disconnect the lines if I ever needed to remove the MLG bow. This would have worked, but I wasn't comfortable with how the line transitioned from the gear leg to down under the bow...I couldn't find a good way to secure the line without causing fit problems with the MLG cover. <br />
<br />
So I rethought the routing and decided to run the lines up over the MLG bow and secure the lines with a few adel clamps. The adel clamps are secured with Clickbond studs floxed to the MLG bow and secured with 2xBID. The lines then go directly to the bulkhead connectors via 90 degree AN-3 hose end connectors. This seemed to work out better and I can still access the bulkhead connections to remove the MLG if needed.<br />

Now that the MLG fairing is done, there needs to be an intersection fairing that makes a smooth transition between the fuselage and the MLG. The key here is that it has to allow for movement between the two. With weight on the gear and on landings, the gear strut will flex up so the fairing has to allow that without breaking anything.<br />
<br />
I really liked Wayne Hick's solution. See his instructions <a href="http://www.ez.org/pages/waynehicks/chapter_09_7.htm" target="_blank">here</a> for details. I will only summarize my attempt at it below.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9AsZSpHuJR0YZIJ3nlbJ1fDDR5IOuA5G8FaHmlpAWWHBkArqCpI7bPK4oFdGt2mYkwu0gCs5A4F8EQz8_gzitekRhn49KUMBwcOPLu2VFeQBP20l5dRR5-9lgr5DJty_Vmqx_L0hJ/s1600/20160827_184948.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9AsZSpHuJR0YZIJ3nlbJ1fDDR5IOuA5G8FaHmlpAWWHBkArqCpI7bPK4oFdGt2mYkwu0gCs5A4F8EQz8_gzitekRhn49KUMBwcOPLu2VFeQBP20l5dRR5-9lgr5DJty_Vmqx_L0hJ/s320/20160827_184948.jpg" width="320" /></a></div>
For starters, I crafted the fuselage side of the fairing out of left over 3/8" PVC foam. This will form the curvature to the fuselage. I used the large end of the Eureka CNC MLG fairing I had trimmed off as the template for the airfoil shape. In the pic, you can see the before and after shaping the contour.<br />
<br />
<br />
<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEip73_5Uob5OYk06CTuFHOJCTfPyYTj1oX5RcYZtuaszTeWNnbF1V1pf74xqCrqEWxGz282r4bzk6_lNtIWbcZA-0EPWlDprK2_vWFgCZZYfx7SRpialXYHQ4sFD_n1PFKI1GfLqxum/s1600/20161016_170143.jpg" imageanchor="1" style="clear: left; display: inline !important; float: left; margin-bottom: 1em; margin-right: 1em; text-align: center;"><img border="0" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEip73_5Uob5OYk06CTuFHOJCTfPyYTj1oX5RcYZtuaszTeWNnbF1V1pf74xqCrqEWxGz282r4bzk6_lNtIWbcZA-0EPWlDprK2_vWFgCZZYfx7SRpialXYHQ4sFD_n1PFKI1GfLqxum/s320/20161016_170143.jpg" width="320" /></a>I glued the top side of the fuselage faring to the fuselage using scrap pieces of 3/8" foam to ensure the necessary clearance between the fairing and the MLG. Afterward, glue the bottom portion to the underside including the MLG cover. Don't worry, this will become a permanent part of the cover but it will stoll be removable when done. <br />

<br />
I glued it to the MLG fairing butted up against the fuselage-side fairing. I used expansion foam to fill in the gaps and began sanding to match the fuselage fairing and gently fair it into the MLG fairing.<br />
<br />
<br />

I'm not sure how I did it but I seemed to be able to shape them almost identical without the use of any templates.<br />
<br />
Not shown (sorry) is the shaping of the back edges curving into the fuselage. See pics below after glassing.<br />
<br />
Once I was happy with the shape, I glassed the bottom of each fairing with 2xBID. I wrapped the leading edge up past the center point and left an overhang at the back supported with card stock.<br />
<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEigbT1XlZmElE_Vdo2NEODx7YMug4byaM8vCLRPiQOMttYpQ9cVh7Vrdn0_Agdj8hbc2oAj2qU1G5GbtR09PqoFCWclXIjQc0R1Z-SLJT_m2NHFWhykmkxvHEoK1ng4h_1n4K6IzqOk/s1600/20170116_135558.jpg" imageanchor="1" style="clear: left; display: inline !important; float: left; margin-bottom: 1em; margin-right: 1em; text-align: center;"><img border="0" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEigbT1XlZmElE_Vdo2NEODx7YMug4byaM8vCLRPiQOMttYpQ9cVh7Vrdn0_Agdj8hbc2oAj2qU1G5GbtR09PqoFCWclXIjQc0R1Z-SLJT_m2NHFWhykmkxvHEoK1ng4h_1n4K6IzqOk/s320/20170116_135558.jpg" width="180" /></a>Here you can see the back edge after glassing the bottom and some trimming and sanding to blend into the existing MLG fairing. Once I had it the way I liked it, I used a piece of card stock to form a template so I could get the other side to match.<br />
<br />
I removed foam from the aft edge and used micro to fill the wedge where the top glass would meet the back edge. It worked pretty well.<br />
<br />
<br />
<br />
After all the glassing was done, I used an xacto saw and a Dremel with a small saw to carefully cut along line separating the PVC foam from the white Last-A-Foam. I used a sharpie to help mark it.<br />
<br />
<br />
<br />
<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNAWL2YuTk5Yf3QLEUFKoHbyq1GvwAwXlYC4QXpVCSVqsoCmY4y2QdwdNtcovcGXHcReneD73PDBnKjdGtgLFECcBZ8wQHfUCrxQU6gUpss3KneCdv2jf9Nk_IJiQhtSek59FoW5W0/s1600/20170128_145038.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="179" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNAWL2YuTk5Yf3QLEUFKoHbyq1GvwAwXlYC4QXpVCSVqsoCmY4y2QdwdNtcovcGXHcReneD73PDBnKjdGtgLFECcBZ8wQHfUCrxQU6gUpss3KneCdv2jf9Nk_IJiQhtSek59FoW5W0/s320/20170128_145038.jpg" width="320" /></a><br />
<br />
After cutting the fairing loose from the fuselage, I used folded over sand paper to clean up the cut line for a nice look. I also removed the gear and painted the exposed foam inside the fairing with micro to protect against water intrusion. I also wanted to ensure water could not get trapped anywhere in the gap so the smooth micro finish helps ensure the water drains out the bottom cut line.<br />

I uncovered a problem after separating the MLG cover on the bottom. I found that I would need to make a few adjustments to accommodate where the corner screws landed for my cover. I didn't see that coming. I couldn't move the fasteners without causing a conflict with getting the gear in and out when needed. So I made adjustments to the intersection fairing on the bottom. I think it turned out fine. <br />

Although the MLG strut has an airfoil shape to it, it's formed in way that puts it out of alignment with the air stream when it's in cruise. That creates unnecessary drag which reduces speed and fuel efficiency. Several builders (<a href="http://www.ez.org/pages/waynehicks/chapter_09_6.htm" target="_blank">Wayne Hicks</a>, <a href="https://plus.google.com/photos/113165833254044329167/albums/5205155251357454977?banner=pwa" target="_blank">Kevin Walsh</a>, and others) have formed fairings over the strut to realign the aerodynamic shape which reduces drag and increases speed. Kevin and Wayne did it slightly different but the result is very similar. Kevin worked to have his made available through <a href="http://www.eurekacnc.com/Cozy%20IV.htm#Gear Fairings" target="_blank">Eureka CNC</a>. These are what I used.</div>

I cut it into 8 pieces, larger widths toward the top and thinner widths where the strut curves sharper. I positioned the top piece about 3/8" gap from the fuselage side and went down to about the top of the brake heat shield. I'm assuming that some of this will end up being trimmed off when the wheel pants are built and installed.<br />

Then I tested the fit by taping the pieces on each leg. I numbered each one to ensure I put them on in the proper order. Note that the closer to the bottom you get, the foam get's very thin and hard to keep from breaking.<br />

To the right...taken after the foam has been micro'd and glassed with 2xBID. Notice the white trailing edge. I glassed the bottom side first and then removed foam from about a 1/4" or so on the top at the trailing edge, filled the gap with micro, and glassed 2xBID on top. This gave it a nice solid sharp edge that should be able to survive a minor hit without permanent damage. <br />
<br />
The bottom was trimmed off to be level while sitting on the ground. Next there needs to be a fairing built for the intersection of the MLG fairing and the fuselage side.<br />

The LXT is the extra torque version of the standard triple puck brakes. I purchased the kit including two wheels, two brake/rotor sets, and two axle sets from Aircraft Spruce and seemed to get a little better deal, including free shipping due to the amount, than buying direct from Matco.<br />

the centerline</td></tr>
</tbody></table>
I had to move the fuselage to a new location so I re-leveled and re-aligned the fuselage per plans. In fact I rechecked it multiple times throughout the ordeal. I was convinced my center-line was accurate, but I was never quite sure the perpendicular line marking the leading edge of the gear strut was accurate. Ensuring it is in fact perpendicular is important because the error grows the farther out from the center-line you get. I finally decided it was as close as I thought I could get it, and using plumb bobs, the leading edges of the strut seemed to be within .05" tolerance. I also set up paper on the far wall to project the center-line and axle positions for adjusting the required toe-in.<br />

I originally drilled the holes before I fab'd the flox pad...I don't recommend doing this. Since the strut is curved, it's difficult to keep it at the right toe-in location while drilling...I ended up with a hole off angle and had to fill and re-drill it once the flox pads were on. I.clamped the axle in place when I drilled the holes and inserted the bolts after each hole to help hold the axle straight and help me drill straight...something hard to do with the long bit you have to use. I then fabricated the backing plate, round vs square, and floxed them in place. <br />

I used some Mother's aluminum polish from your local Auto Zone aircraft supply house to put a high gloss finish on them to reflect radiant heat. Lastly, they have to be bent per Bernie's template to clear the brake calipers.<br />

<br />
Now that the gear strut is in place, I can complete the removable cover for the bottom access to the "hell hole" where the main gear is mounted. Other than the gear mountings themselves, the only thing that will be in this area is brake line connections I think.<br />

The cover has been fabricated but it has no way to be mounted. As mentioned, I followed <a href="http://www.ez.org/pages/waynehicks/chapter_09_5.htm" target="_blank">Wayne Hicks method</a> of fabricating the cover. This continues into the mounting flange and fasteners for it. I first taped off the edges of the inside of the cover with packing tape to prevent epoxy from sticking. Then I bondo'd craft sticks to the cover so it would sit flush over the access hole.<br />

It is a hinged flat board that deploys from the belly just behind the front seats. The plans call for a mechanical mechanism to deploy it however most builders today convert this to an electric actuator.<br />
<br />
<b>Building the Brake</b><br />
The building of the landing brake started in an earlier chapter when the brake was cut out but then re-glassed back into the fuselage bottom until Ch 9. So the completion of the brake starts with cutting it lose.<br />
<br />
I decided early that I wanted the hinge for the brake to go almost the full width instead of just 10" per the plans. I'm hoping this will keep it from warping the way several builders have reported. To do this, all I really had to do is adjust the number of attach points/screws. I'm also widening the wooden support the actuator connects to to provide a little more crosswise support. My hinge runs ~22" of the ~24" width of the LB.<br />

<br />
<b>Installing the Brake Hinge Support</b><br />
I used 7 screws to attach the hinge to the fuselage and 8 screws attaching the hinge to the LB. Other than the added number of screws/slugs to the hinge line, everything else pretty much followed plans.<b></b><br />
<br />
<br />
<b><br /></b>
<b><br /></b>
<b><br /></b>
<b></b><br />
<b></b><br />
<b>Preparing the LB Cavity in the Fuselage</b><br />
After securing the LB-23 hinge support into the fuselage, I routed out the interior of the landing brake cavity using a dremel routing tool to make room for the glass to be added.<br />
<br />
<div style="text-align: left;">
I then located where the actuator would come through the bottom and beveled the foam to that area. The cavity was then glassed per plans. At this point, each slug buried into the foam of the fuselage was drilled and tapped for 10-32 screws and the brake was test fit. In order for the brake to hide nicely under the fuselage, micro must be used to fill the remaining depression. I taped off the brake edges and the hinge to ensure release and filled the edges and the surrounding depression with micro. Then I closed the brake flush with the bottom of the fuselage to let cure. <b> TIP:</b> I would recommend putting some kind of release agent on the tape. I almost epoxied my LB closed :-) . This process essentially makes a mold of the inside edges and perimeter of the brake in the fuselage bottom so that when it closes it basically disappears nice and neat. See video at the end.</div>

<b>Installation of the Actuator</b><br />
I'm using a Firgelli actuator, model <a href="https://www.firgelliauto.com/products/feedback-rod-actuator" target="_blank">FA-PO-150-12-4</a>. It has a 4" stroke, 150lbs of static force, and a feedback potentiometer in case you want to wire it up to an electronic indicator. I made glass brackets similar to Wayne Hicks however I only ended up using the larger one to attach the actuator to the back of the seat. <br />

A picture would be good here, but at any point on the bracket there are 8 layers of BID. I used a scrap piece of foam to form around which was cut the width of the actuator attachment. I let it cure, cut it to shape, put adjustment holes in it to allow me to adjust the closure of the LB once installed. <br />

The fuselage side bracket is mounted in the back of seat on the passengers side close to the center seat support. I glassed an oversized piece of birch plywood on the back of the seat.<br />
<br />
Between the seat and the birch, I embedded two EZ-point locking nuts vertically where two bolts hold the bracket in place. The actuator is then attached to the bracket with an AN Pin and castle nut to secure it. For the LB bracket, I simply used the aluminum brackets, part no. <a href="http://www.cozygirrrl.com/aircraftparts.htm" target="_blank"><span style="font-size: 13.3333px;"><span style="font-family: "verdana"; font-size: 8pt;">CZLB-18</span></span></a> available from the Cozy Girrls.<br />

Next up was installing the MG-1 & MG-2 fuselage hardware to support the landing gear. Instead of making these parts myself, I ordered them from the Cozy Girrls. As per all the parts I've seen from them they were first class. Any parts that are destined to get floxed to something else come professionally abraded and ready for attaching. No sanding required.<br />

<br />
After installing MG-1/2, I drilled out the center hole and installed the MKMG-1 bushings w/flox. When you do this, fill the end that inserts into the hole with candle wax to prevent flox from getting inside. This worked great. The bushing insert from the MLG side of the attachment hardware. Once the bushings were installed, I inserted the MLG threaded stud and let it all cure nice & straight.<br />

<b>Gear Attach Tab Mounts:</b><br />
<br />
While all that was curing, I began the last stage of completing the gear strut attachments. This included drilling out the tabs to the correct size for the MKMGA tubes (also a Cozy Girrl part) that the attachment stud will run through, floxing the underside of the tubes, finishing off with some BID to cover and secure the entire assembly, and lastly floxing/glassing some washers on the outside of the assembly.<br />

Take your time drilling out the tabs as they will build up heat and you don't want to damage the surrounding glass. Use the procedure outlined in the plans for drilling a little at a time inside and out of each tab until there is just a little left in the middle. That will keep your holes nice and straight. I found that my drill was just a little undersized compared to the tubes but my round rasp I bought at the beginning of the build was perfect for finishing it out. <br />

Before floxing them in I rechecked the alignment in the fuselage after the bushings had cured. All was good...time to glue!<br />

The plans call for inserting foam under the tubes and then glassing it all together. I found that some folks have found the foam to wear or get destroyed over time and recommended just filling the area under the tubes with pure flox...so that's what I did. The last step was to flox washers around the external portion of the tubes & cover w/BID.<br />
<br />
<br />
Lastly, the gear strut was remounted into the fuselage to see if it all worked out correctly. As you can see by the pictures below, the clearances between the gear attachments and the fuselage attachments of mine fit amazingly well. I dare say almost perfect. I am still amazed at how well this all goes together.<br />

It was time to see how accurate the alignment of the strut was when installed in the fuselage. This is the ultimate test of how well I performed the previous steps. I leveled and aligned the fuselage per the plans, marking F.S. 124.25 (firewall) and 108.25 (leading edge of the main gear strut) and ensuring everything was square and straight. In fact I did it multiple times using my large squares and a laser. This is not the step you want to screw up because some major holes get drilled based on this alignment that would be difficult to correct.<br />

After leveling the fuselage, I centered the strut between the bulkheads and dropped plumbs from the strut leading edge. I found both sides a little forward of where there were supposed to be...one about .15" forward and the other about .25". After a little adjusting of the bulkhead holes, I was able to bring both side to almost perfect. You can see in the pics the plumb basically dead on the line...just hope my line is actually correct :-).<br />
<br />
<br />
<br />
<br />
<br />
After getting the the alignment set, I rechecked the level of the gear...amazingly still level !<br />

The last step is the installation of the mounting hardware to the bulkheads & the gear attachment tabs.<br />
Onward, cabChadhttp://www.blogger.com/profile/00418339036114219227noreply@blogger.com0tag:blogger.com,1999:blog-1093745096022479495.post-16142328864331168902015-09-13T17:26:00.000-05:002015-11-01T19:06:45.239-06:00Ch 9.4: Main Gear Cover (1 of 2)While I'm waiting for the main gear mounting parts to arrive from the Cozy Girrls, I decided to keep moving and work on the main gear access cover.<br />
<br />
I did not follow the plans method for this. Instead I followed <a href="http://www.ez.org/pages/waynehicks/chapter_09_5.htm" target="_blank">Wayne Hicks</a> method which I highly recommend. Earlier when prepping the bottom for glassing, I did not make the joggles with the foam at the front main gear bulkhead because I new I was going to use this method. With this method, you don't need those joggles, you don't need the aluminum slugs installed into the edges of the bulkheads, it's much easier, and will be form fitting when your done.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEge6Jjf0QnzwR0F-oXKB4aBjsfYNO3-L-GIaC_Xumzj1bryHcgfnW0OnIlswnEM35lpEXihOMDs6BSS98hNEHevvKpB1h3HU_rxIO60j14eRignLBwvYnbnbIsArVC6drAyf2gk7F1B/s1600/20150515_143533.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEge6Jjf0QnzwR0F-oXKB4aBjsfYNO3-L-GIaC_Xumzj1bryHcgfnW0OnIlswnEM35lpEXihOMDs6BSS98hNEHevvKpB1h3HU_rxIO60j14eRignLBwvYnbnbIsArVC6drAyf2gk7F1B/s200/20150515_143533.jpg" width="150" /></a></div>
The first step was to stuff the area between the bulkheads with foam. I found enough urethane foam scraps around so I didn't have to buy any.<br />
<br />
Once the foam is stuffed, I sanded it down to the shape of the fuselage bottom and NACA scoop. The picture to the left is in the middle of this process.<br />
<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjFu8pLU8c4owTTD1GXOr6etMW1dwk9hcCmNfGBnDvMITSBlczlOJcuTeypABlPFTvVAH0zh62hKf2lX69YCIksFWFdFVMvtiPI-dwStUZ0Jl-5vQoTpqMcSWDoL7wYy3On8OQkiweO/s1600/20150517_101959.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="150" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjFu8pLU8c4owTTD1GXOr6etMW1dwk9hcCmNfGBnDvMITSBlczlOJcuTeypABlPFTvVAH0zh62hKf2lX69YCIksFWFdFVMvtiPI-dwStUZ0Jl-5vQoTpqMcSWDoL7wYy3On8OQkiweO/s200/20150517_101959.jpg" width="200" /></a>Once sanded to shape, I glassed the NACA scoop with 2 ply BID and then the rest of the bottom of the cover with 2 ply BID as well.<br />
<div>
<br /></div>
<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrNe79W9SoRpgl7l5dtDa88R1M3RvNhKNyfNr-H79OT0pNWuhE4m3YNo0-L37tMS3lqMa43jvEIE6hmVtbtff8bnW1j3bjKcF7xlXm3ePARx8T0DMJvSmNPVrP1fo1hMIimLrVww4l/s1600/20150523_161220.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="150" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrNe79W9SoRpgl7l5dtDa88R1M3RvNhKNyfNr-H79OT0pNWuhE4m3YNo0-L37tMS3lqMa43jvEIE6hmVtbtff8bnW1j3bjKcF7xlXm3ePARx8T0DMJvSmNPVrP1fo1hMIimLrVww4l/s200/20150523_161220.jpg" width="200" /></a>After the glass cured, but BEFORE I removed it, I attached two straight supports with Bondo across the NACA scoop. These served to keep the cover in the proper shape while I work on the underside. The picture at the left is just after I removed the entire foam plug with the top completely glassed.<br />
<br />
After sanding the forward/aft edges of the cover to fit, I removed all but approximately 1/4" to 1/2" of foam all over the other side of the cover and all the foam around the perimeter of the cover about 1" wide. <br />
<br />
There needs to be room for the gear so, as recommended by Wayne, I sanded some indentations under the NACA portion to ensure the cover would fit over the gear without rubbing. Then I glassed the underside with 2 ply BID and shaped.<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjs7RtKtakj1nSqQrEEO19mVC_zY72ULuh21hh7MY-T7J2u9v87yhg5x2vdLAD8GKtDz_6SM_yIQLRpTlX91CU24VNIAchMoXQF_vGQuyfEtP9vwfKHNYz7JKjDSaXyYxtpXO5Zkuab/s1600/20150524_173340.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjs7RtKtakj1nSqQrEEO19mVC_zY72ULuh21hh7MY-T7J2u9v87yhg5x2vdLAD8GKtDz_6SM_yIQLRpTlX91CU24VNIAchMoXQF_vGQuyfEtP9vwfKHNYz7JKjDSaXyYxtpXO5Zkuab/s320/20150524_173340.jpg" width="320" /></a><br />
After that, I installed 2 ply tape along the forward and aft edges to reinforce the bare edges for the fasteners.<br />
<br />
The only thing left to finish this up is to install the ledge and fasteners along the bulkheads that will hold the cover in place. That will have to wait until I get the gear mounted because it would be harder to work on the installation of the gear after the cover mounting flanges are in place.<br />

<br />
Once the outside tabs are built and shaped, the inside tab layups are pretty easy. This pretty much went according to plans however I did add layers of glass (~10 as I recall) to try to get the total thickness of each tab to approx 1" like the drawings seem to indicate. You'll find multiple comments about this in the Cozy Group archives. According to the archive comments, what's important is that the min # and type of plys are used regardless of how thick (or thin) it comes out to be in the end.<br />

The one problem that might be created by added the extra plys is that there may be a bit of a stack up of glass where the glass makes the turn from vertical to horizontal over the gear bow...particularly on the thicker leading edge. There might not be enough clearance for the MKMGA cross tube to be mounted without having to sand out a little glass in the middle first. Since I added ~10 plys, I don't consider this much of a problem as I'll just be removing some of what I added.<br />
<br />
<br />
<br />
And here are the tabs after the inside layups had cured and were trimmed. You can see how the plys stack up on the leading edge (left side of the left hand pic below). That's where I might have to trim a bit out of the middle to make room for the MKMGA mounting tubes.<br />

Now that the gear was jigged, it was time to fabricate the attach tabs which form the structural connections for connecting the main gear to the fuselage. There are two layups. First, a 25 ply UNI layup goes from one side, over the underside of the gear (remember the gear is upside down), and down the other. The second layup is a 20 ply BID layup that just wraps over the underside of the gear on top of the 1st layup. In all, the layups end up 45 plys thick except right in the middle of the underside of the gear where it will only be 25 ply.<br />

The thickness of each ply of UNI and BID should add together to make this layup approx .5" thick. But mine, along with several others I found in the archives only came out only around .38" - .4" thick. The archives indicate that as long as you are sure you have the correct number of plys, that's what counts. However, there's also an email in the archives from Nat that states to just add plys until it's ~.5" thick. I ended up adding 8 additional plys of BID, gently clamped, and got them to .5" or very close. I may not have needed to do that, but if nothing else, I'll have a little extra strength where it counts.<br />

</tbody></table>
After drilling the holes using a hole jig like described in the plans, I cut out the tabs to the ~3" wide shape with the 1.5" radius around the attachment hole. I used my Fein tool to cut a shallow line around the shape, then a small chisel to take off a few layers at a time. Wash, rinse, repeat until all the unneeded glass is removed. When I got down to just a few layers left, I just blended the remaining into the gear leg with a sander so as not to accidentally cut into the torsional plys.<br />

</tbody></table>
One critical part of this is being sure to get the glass going down<br />
the jig to be perpendicular to where it crosses the gear leg. When the glass is wet with resin and heavy with all the plys, it can slide down the gear leg a bit. (Ask me how I know this :-) ) When this happens, the attach tabs will end up being angled over to where the hole is which will compromise strength a bit. My fwd/port side tab ended up about 10 degrees. This ends up compromising strength somewhere between 7-10%. According to Marc Z, this isn't significant. This, combined with the fact that it just didn't look right, led me to a do over on the port side attach tabs.<br />

Again, I ended up adding 8 additional BID plys to get the thickness to ~.5". This time I made sure to draw a bold center line where I wanted the plys to go as well as some edge guidelines to help me make sure things stayed centered. The resulting attach tab was nearly perfect.<br />

This was just the external plys, now it's time for the internal attach tab plys. Onward, cab<br />

As bought, the strut doesn't have any way to attach it to the fuselage so you have to provide those by way of fabricating attachment tabs.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="" style="clear: both; text-align: left;">
Note to future builders...Don't rush these steps. Take your time, check and recheck measurements. The more accurate you are on each of these steps, the easier job you'll have installing the strut into the fuselage and having everything line up with minimal adjustment. </div>
<div class="" style="clear: both; text-align: left;">
<br /></div>
<div class="" style="clear: both; text-align: left;">
The first step is to build the jig. I built a perfectly vertical backboard and laid out the alignment marks that define the center line and location of the future attachment points. A check of the FAQs indicated that it is likely that one attach point location would be slightly higher than the other just because the strut may not be perfect or you may have had some variation in the thickness of the previous 8-ply layups. I had one side that was .1" higher. The FAQs say to use the higher of the two and match them. Now that the forward attach point located, I built the jig box per plans, bondo'd it to the strut, and transferred the points from the backboard to the jig.. This was pretty straight forward. </div>

With the jig built, I moved it to the work table and positioned it per the plans. After some shimming and leveling, the strut is aligned such that the LE of the strut falls exactly 9.25" in front of the back edge of the jig. This further aligns the strut and jig in such a way that all four attach points should be at the same distance above the table. This then allows you to locate the rear attach points based on the measurements of the front points you already located.<br />

<div>
<br /></div>
<div>
<b>Glassing the Glass...</b></div>
<div>
The next step is a 4 ply layup, ~35 degrees to the leading edge (LE), that provides the strut torsional strength that it doesn't have out of the mold. The entire strut is made of S-Glass with all the fibers laid in the same longitudinal direction. Without these layups over it, there's nothing to prevent twisting from landing loads. You can see my ~35 degree alignment marks in the picture. The glass runs from the LE up around the trailing edge (TE), and back down to the LE again...maintaining the 35 degree angle. </div>
<div>
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAXUZhaxtLnXA47RyQPlbzm7VdEFLO3TDRBS5tolPLd_YJkJ8Bo7-lAD-GW63Oe_A_DvbatCxnwi2kG50C_KNBYxZIFUmB4V675yIquy5lIg_eIQxxGSTWqjuP5h5WdheJEGMqEo4W/s1600/20150206_125140.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="150" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAXUZhaxtLnXA47RyQPlbzm7VdEFLO3TDRBS5tolPLd_YJkJ8Bo7-lAD-GW63Oe_A_DvbatCxnwi2kG50C_KNBYxZIFUmB4V675yIquy5lIg_eIQxxGSTWqjuP5h5WdheJEGMqEo4W/s1600/20150206_125140.jpg" width="200" /></a></div>
This layup took me a lot more time than I thought it would. What I estimated to be a 4 hr job took me 7 hrs just to get the first three ply's laid down. At that point I was so tired I decided to peel ply and finish the last layer another day.</div>
<div>
<br /></div>
<div>
My difficulty was getting the long pieces of glass running the correct direction while at the same time ensuring there was enough on each side of the strut to cover it. The first layer wasn't bad because I could get it in place on the strut and then raise it a little at a time to put epoxy under it. After the first layer though the remaining epoxy was sticky and made it very difficult to get the glass laid correctly. I came back in the next couple of days and finished the job with that last layer. </div>
<div>
<b><br /></b></div>
<div>
<b>A Place for Brake Lines...or Maybe Not.</b></div>
<div>
Next the plans have you flip the strut over and install tubing for brake lines at the TE. I skipped this task because I'll be installing gear leg fairings from <a href="http://www.eurekacnc.com/Cozy%20IV.htm#Gear Fairings" target="_blank">Eureka CNC</a>. They provide a more efficient airfoil around the gear legs which reduces drag. It is expected that you can pick up ~3 knots with these. The prefabbed fairings have a cutout for the brake line conduit already built in.</div>
<div>
<br /></div>
<div>
<br /></div>
<div>
<b>More Torsional Layups...</b></div>

Now four more ~35 degree layups...these wrap from the TE up over the LE and back down to the TE again. <br />

<b>(TIPS)</b> I did three things different this time. First, I u<span style="text-align: center;">sed 15" wide strips of glass and I marked them with tape, cutting down the middle. The tape keeps them from unraveling at the edge. I cut the tape off once it was laid up on the strut so I could adjust groups of fibers individually.</span><br />
<br />
Second, I raised the strut which put it at a more comfortable level to work on and allowed me more room to deal with the glass wrapping underneath. I still couldn't get to the 1/8" gap the plans want you to try to achieve. Frankly, I don't see how anyone can do that. I did the best I could and then sanded the rough edges I had to a nice fade into the strut.<br />
<br />
And third, I made sure to apply fresh epoxy right before each subsequent ply after the first.. This allowed the glass to be moved around easier to get it aligned correctly without sticking to the previous ply. <br />

<br />
Ok...down to the last strength reinforcements of the landing gear bulkheads. This one beefs up the area between the forward and aft LG bulkheads themselves. This is the area where the main gear bow will actually be installed.<br />

<br />
The last reinforcement went so well using the template, I decided to try it again on this one. I thought it might be the only way I was going to get the glass fibers running the correct direction all the way around.<br />
<br />
I first pieced together a template using pieces of paper and tape. I used a sharpie to mark the corner areas and planned to trace these on to the plastic before I wet the glass so I could get it positioned correctly on installation..<br />
<br />
Since the area to be glassed has a major bend in it (see right side of pic), I had to decide where to cut it in order to get it to lay flat for cutting the glass. It is mentioned in the plans that you'll have to cut the glass somewhere and overlap it or it will otherwise bunch up....but make sure you don't overlap on the hard points...these need to be flat.<br />
<br />

Looking around at other builder sites, I came across <a href="http://cozy.caf.org/chapter-09/index.shtml#step01" target="_blank">Charles Fernweger's builder site</a>. He showed a template that looked a lot like mine...giving me a little confidence that I was on the right track. He cut his from the front corner, where the three separate planes come together, diagonal up the 90 degree inside corner in the forward bulkhead. When the template is laid flat, you get something like the top picture to the left. The cut I made is represented by the open triangle. <br />

<tr><td class="tr-caption" style="text-align: center;">Paper template<br />

</tbody></table>
I closed this gap up with another piece of paper running horizontal until it met the other side of the open triangle like in the 2nd pic. Note this is flipped as if for the other side.<br />
<br />
When cutting the wet glass to shape, I made one cut from the location of the sharpie in the 2nd left pic, to the 4-way intersection. The 4-way intersection is the corner where the three planes meet (fwd upper bulkhead, fwd lower bulkhead, and fuselage side). Now when I installed the glass, and it folds up, I had a side of excess glass to overlap onto the angled upper portion of the fwd bulkhead for a strong bond. I hope that makes sense...EZ to do, hard to explain.<br />
<br />
<br />
After the "all over" reinforcement is complete, there is one more 2xBID that goes over the hard points just like the other reinforcements. Using the same process, I cut 2xBID 19"x 6" and laid it in from hard point to hard point. EZly done. (<b>OOPS:</b> The next morning when I completed the pilot's side I realized that I had accidentally made this lay-up with 3 ply's instead of 2...oh well...I guess a few extra once's wont hurt.)<br />
