Since the belly wood can only compress so much, with the adding of glass to put more strain on it... I tried the glass w/resin and the bow blow. The glass held it but it still broke.
I found using TB III & glass worked way better, but not as good as linen & TB III. This is just what I found by doing that.
I made a red oak board bow w/Air Backing. It's a 70"N2N pyramid style long bow that pulls 51#@24"
