bamboo backed red oak?
« on: July 22, 2011, 04:53:58 pm »
I am about to glue up a bamboo backed red oak bow. I havn't used this combo before and I have heard it can chrysal pretty bad. If I make the bow seventy inches and tiller carefully, do you guys think it could handel a 29 inch draw safely at around 50-55#? :-\

I think it could if you use a very dense piece of red oak. I would just look for the most dense piece you can find and ignore grain to an extent as your gonna glue up a laminate. I wouldn't go too narrow as well on limb width.

get the bamboo as thin as posible.  if you pre cut out the profile of the bow on the bamboo and then thin it all the way to edges you should never have overpowering issues with hard woods as a belly.  this also gives you a very even taper in your bamboo.  about 1/16 over all taper or more from fade area to tip.  Leaves more room for more oak and less set as well.

It's definitely possible. Check out this fantastic boo backed red oak made by Dauntless.

I imagine you can, I've made two boo backed red oak board bows, both were only 45# at 28" though. It shots great and I have seen a bit of chrysaling, but it hasn't caused the bow to explode yet and I've been shooting it for about a year now :) That's a great looking bow Dauntless made.

And leave the belly flat as a pancake to equal the compression out the best it can. Round the edges only slightly.
