Learning to Work With Fiberglass - Exercise #2

In exercise #2, I built a tapered beam made of a piece of medium density foam sandwiched between layers of fiberglass.  This is designed to demonstrate the strength of composites and introduces you to working around curves.  After the part cured, I had each of my two oldest sons stand on each end (~100 lbs each) while balancing it across a broomstick...This stuff is strong.  The lesson learned here was that it's easy to get air bubbles in places where the fiblerglass is difficult to keep tight inside corners.  Oh yea...and did I mention how strong it was?
