glass question

[hightop_hunter]

I would like to post a question for all the glass bow makers out their. I have made 6 self bows with some degree of success but I haven't tried my hand at a fiber glass bow.


so here is my question why is it that fiber glass recurves are so wide? dose this affect the speed/efficiency of the bow?


thanks

I'm not a pro, and my experience comes from making a lot of mistakes. My theory on width is that it provides stability. Glass recurves are wider but they are also thinner and lighter. Light and thin offsets thick and heavy and is less prone to limb twist. I made a narrow recurve for my son and it wanted to roll over and unstring itself. I just hacked most of the curve off and made a shorter hybrid.

You need the width to get the weight up since the limbs are thinner.

Roy from Pa  that is my question why make them so thin wouldn't they be faster if they were thicker instead of wider.?  less resistance on the bow limb?.... I am no physicist but I would think thats how it would work.

I do understand about wanting to unstring them selves. I made a horn beam round belly bow that was prone to falling out of its nocks.

They draw smoother when they are wider, and dont stack as fast.
