Hey Guys,
   I'm getting ready to build an Ipe prototype bow. I was wondering for you guys that use Ipe how thick your belly is lets say for a 50# bow. I'm not looking for exact dimesions b/c the design of the bow will play a big part. I know you can build a great bow with very little wood. I'm just looking for a ball park figure. Thanks

Adam

Start with about 1/2" at the fades and 1/4" at the tips.  Ipe is very strong, thus it need not be as thick as other woods.  Hickory and Osage start at 5/8" to 3/8"

I know for the one I built, I needed 5/8" at the handle for the handle not to pop off.  Or you can put a power lam on it between the boo and IPE.
