Mark, the bow is sitting in the oven, waiting for the rain to stop.
Semo, I didn't measure the limb thickness before I started. I sanded off about 1/8"-3/16" then glued on two .080 Ipe lams, for a total thickness of .160
Because the Ipe is so strong in compression I used a round belly. This bow weighs 17.5 ozs and is the nicest shooting woodbow I've built.
