I need some suggestions for about as un-primitive a bow one could make...

I think I've decided...I have a lot of formica strips and I have access to garlock tubing at work. I shaved some garlock down to the rough shape I wanted and glued it up between a couple pieces of formica in my fiberglass magyar mold. Lashed some poplar sayahs on the ends and it pulled and stretched okay but I made the limbs too thin on both axis. Pull was only maybe 15~20lbs, and the limbs want to twist under pressure so I had a hard time drawing it and when it went back the limbs would twist around to basically make the thing "inside out".
I'm going to shave the garlock down into three or four strips and stack them this time, and put two strips side by side to make the thing 2.5" wide at the widest. See how that holds together. Then I'll have to find something else for sayahs...a couple of the other competitors are having fits over it.

Hello, just a thought, as an old machinist,,, How about using free floating Lexan, similar to the way car rear springs are stacked? poundage could be adjusted by adding or removing "leaves". Also, if I understand the rules, a cable back would help hold everything together,,, Just a thought :) "bowstring"

One thing to keep in mind for backing is that Gorilla Duc Tape. That is some tough stuff.

It's implied lol...plus it's a good-natured no prize competition.
I haven't thought about cable bows...that'll make things a bit less complicated.
