We got a Bear Cub recurve for my son.
It's AMO 62" and 27 lb. draw.
The string that came with it was obviously too short - it was only 57" and the brace height was almost 12".
So I bought a 58" long string from 3Rivers, which got the brace height to about 9", which still looks very high to my eye.
What would the correct brace height be?
What would be the consequences of too high of a brace height (I expect it to settle in at around 8-1/2" once the string stretches).
I am a little worried about over stressing the bow because it has some long cracks in the fiberglass on the front (belly) of the bow. Since the front is under compression, it is probably not as bad as if the cracks were on the back of the bow (the backing is under tension).
I have the bow strung right now, but will probably suspend a weight from the string to stretch it. The string is for bows up to 40# (14 strand). My research shows that a string usually has max tension in it when the bow is not drawn, and that is about 1.2 times the draw weight of the bow (string tension goes down as you draw, then goes back up near full draw). I figure I can safely hang 70 pounds overnight to pre stretch the string (I'd imagine with safety factors mfrs use the string would be safe to well over 100 pounds).
If that doesn't get the brace height looking better I will have to order him another string (ugh). The reason I went with 3Rivers instead of a custom string was to get it fast, and to keep cost down (My son doesn't need an expensive string).
So, whatdya think?
