Title: 1/2” red oak board question
Post by: dave young on January 03, 2018, 05:15:50 pm
I have a nice 1/2” thick, red oak board, I was wanting to turn into a pyramid bow. My question is, will I have trouble with the glued on handle popping off if I do this? Best way to prevent that?

Make the handle fade out beyond where the sides fade down to  the handle. So it will already be thicker when it narrows for the handle.

Make a leather or cork riser that will bend with the bow.

It depends, how wide is the board, a board a full 2to 2-1/2" wide 64" long will this a pyramid style bow in the 50# range under a half inch thick in the limbs. Also glue the handle on in thin strips will help to

When employing a glue-on wood riser, it's possible for it to "pop off" when limbs are bent. Preventing this is relatively easy, but may not be obvious. Slope of transition from top of riser to limb (the fades) needs to extend into the limb itself.

Note that slope of fades extends into thickness of limbs.

As others have mentioned, it also helps if riser is made up of relatively thin pieces, particularly the 1/2" nearest limbs. I often use some 1/8" to 1/4" laminations.

Good luck!
