I have made two Hick Backed Osage Bows recently.
First one Blew up directly across the grain...really clean break at full draw.
I saw nothing wrong with the quartersawn slat or the Hickory backing. I think posted that break on here somewhere.
Well I just blew another one on the tree at low brace. I was very picky on my slat and backing strip and all.
Saw absolutely nothing wrong....only thing I noticed was that the Osage slat seemed not very dense, and the limb thickness seemed unusually thick down thru for all the weight I was pulling. So I assume the Osage was not dense enough and was just doomed to fail from the start.
It broke right off the fade....if I recall both slats were from the same supplier(whom I will not mention).
Bummed out for sure....I think I'll stick with Ipe for a while.
Really kills the confidence level.
