Crack on back ?
« on: January 16, 2013, 02:50:31 pm »
Working on a osage bow that has alot of problems. Started out 1 1/2" and by the time I got most of the problems work out it, ended up 1". That didn't surprise me.
I'm going for #50@27" got to 20" and CRACK  ::) this didn't surprise me either.
Here's the problem, cracked in a Y shape at an open knot about 6" up from center. It had a small hing there and I was staying away from it.
I super glued and now could I sinew just that area or go to a lighter weight? May end up being a stake.
This is a stick I thought I'd try with out to much hope in the beginning.
I highlighted with pencel the crack.
Any ideas?

I would skip the sinew wraps and just keep going. Its osage. The left side of the knot is wider and will do the work. Consider how wraps work and what they lend to the bow. Then ask if it will really help it.

Oh Well.
Thought I'd go to #45@27" so it would be alittle less stress on that limb.
Everything was looking go, got #45@25" and POW!
On to the next one. I have another narly stick just waiting but this one will have to be about #30.
Thanks for the replies.  ;D

Those cracks are the go for broke cracks. You just pretend they arent there and see how far you get. Wraps work good if you lift a splinter or even split a side out. They generally wont help tension related problems.

The V of the crack seems to be concave therefore the sinew wrap won't help in this case as it won't support the wood

This bow had it's problem from the begining, but I had to try. I liked the knot hole.
I,ve got an elm on the tree now.

What if you wrapped in a triangular pattern starting from around the bow just below where the branches of the Y crack starts and then up through the hole and then back down to the other side of bow and then around the bow again, gradually working your way up to just below the hole, that way securing the sinew with each new course around the bow? It seems like that might put the right hug on the crack.
Did that make any sense?

I'm guessing the lower fork of the crack went on out to the edge?
