Title: bamboo backed red oak?
Post by: Lee Lobbestael 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#? :-\

Leaves more room for more oak and less set as well.

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.
