|Aft heat duct assembled with 7-ply reinforcement|
curing over seat belt attach tube.
Here you can see the aft heat duct assembled and the 7-ply reinforcement of glass lay'ed up on top and over the seat belt attach tube just like I did in Ch 6.
The part is installed per normal (flox, 2 BID tape the seams, ect) and then an additional 7-ply reinforcement is added across the seat belt attachment tube and along the floor approx 6". I tried this as one 7-ply layup and it worked ok but I didn't anticipate that the 7 layers of glass would be hard to lay down correctly over the attachment tube. I got it down ok with no air bubbles but was worried for a little bit. This is also done on the front seat and I did it the same way...probably shouldn't have...I wasn't as lucky getting it all down properly and had a few air bubbles to fill. I also widened and lengthened each piece of glass by 1/2 " to allow for a smooth transition of the layers. The black lines you see are my sharpie marks for cutting. You can see that the plys got a little unruly while laying them down but it came out ok. I don't know how some builders get such neat, straight, and pretty glass work...I just can't seem to do it.
TIP: If I were to do it over again, I would follow a tip from Marc Z in the archives and split the length of the plys so that I could lay up alternating plys on each side and get each ply to lay down correctly across the top, overlapping them from each side across the width of the duct. You'll have 7 ply's on the floor but 14 on top of the duct.
Ok....seat belt attachments done...time to check back in with the headrest.
