Elm self bow dimensions

[perry f.]

I have an elm stave that I plan on making a self bow from. It is 68" long and I want to make a 66" long bow, nock to nock. I'm keeping the width 2" out to 1" past mid limb and then taper to 1/2" at the tips. I was wondering what thickness I needed? I'm wanting to build a 50-55# bow, and I'm also thinking about recurving the limbs. Thanks!

The way I determine thickness of bow limbs is by removing wood until they bends evenly and together and are at the draw length and weight I'm shooting for.
Those dimensions should work fine. If you find the limbs getting too thin begin tillering from the sides of the limbs.

I will be watching this one for sure!  I have several winged elm staves waiting to be made into bows...please post lots of pics!

If you're looking for where to start, 9/16" - 5/8" is a good starting thickness for those limbs, but you will have to tiller it like Pat B said.
Just remember that wood is easier to take off than it is to put back on.

I agree witht he Captain.  5/8" is a good starting point.  You will end up with 1/2" or so but start thick.

Bringing this old thread back up...Perry did you ever get that elm bow made?
