RE: Selfbow break
Yeah, I think that's a bit much too, kinda like swatting a fly with a sledgehammer. Maybe that's something you could try as a last resort. You might consider wrapping the entire handle area with thread, from just above the crack all the way down to the same distance below the grip. Then stick on your shelf plate and leather handle over the wrappings. I did that on a board bow that kept popping off the wood I'd glued onto it to build up the handle area. I used 50-lb test braided dacron trolling line for that, and it never budged again.

BC, that crack is actually in what is essentially a non-working area of the bow, so I think it's not that big of a problem. What I'd do, if it was me, is this:
1: Take some liquid super glue and try to get some to seep down into the crack.
2: If not, coat the area with epoxy and wrap it tightly with heavy thread, color of your choice. Upholstery thread is what I'd recommend. Just one or two layers should be plenty. Finish the wrap just like you're serving a string to make it look nice. Just make sure to keep the wraps tight. From the photos, I can tell you'll have to remove your leather plate in order to wrap it right. If you've got access to sinew and hide glue, that'd work too.
3: Coat the wrapping with polyurethane to finish.
4: To make the wrap look like a decorative feature instead of a repair, measure down the same distance from the center of the bow and put another wrap there. Epoxy, wrap, poly, just like on the actual repair.
I've done this repair even in working areas of limbs and had it hold for a long time, so it should do just fine right there next to the grip.

RE: Selfbow break
I was going to wrap with some string material like 450. Think that would be a bad idea? If you guys notice the shelf material is sinew. Should I cut that out or just wrap over top of it.
I am thinking wrapping the whole grip area to make it look decent. But haven't made up my mind.
I was looking more at this, and notice that crack is in a very weak area.

RE: Selfbow break
The shelf mat'l is sinew?? First time I've heard of using sinew for that.[:-] Somebody must've had more sinew than he needed to use it like that. But that's beside the point.
If it's sinew, I'd leave it be and wrap over the top of it. Most string making mat'ls are coated with wax. If you intend to use it, then get as much of the wax off as you can before using it. Upholstery thread - any fabric store will have it - or braided dacron fishing line will do both a good job and you won't have to worry about wax.
Just be aware that wrapping over the sinew and then applying another shelf covering will change your degree of centershot. In that pic there, it looks like that sight window is cut practically to center anyway. I don't like to critique other's bows, but I think that's cut way too deep. Probably what weakened it in the first place.

Yep, watch for wax. If its string material, it will be pre waxed. You might useraw hideto wrap it. You can get a dog bone, soak it, untwist it. Let it dry and pound it into fibers that you could wrap it with. Ive seen some cool wraps done this way. Hemp cord is good to wrap with as well and adds to the traditional look.

It is sorta close to centershot.
Glad I asked about the material. Never thought of the wax.

RE: Selfbow break
I have yet to cut a shelf into any of my selfbows. It probably helps getting used to shooting them but I have gotten used to no cut in shelf.
Anyway. I agree the shelf cut in was my first thought about why it happened. But I agree with Arther I would wrap it. I would suggest sinew if you can. It shrinks some as it dries so it gets tighter as it tries. But other materials work too.
Good luck

Well, good news keeps rollin in. I got ahold of the bowyer who made this bow. The guy is kind beyond words. He told me to send it back. He wants to wrap area with a butt load of sinew, then he wants to take elk horn and smooth it down and reinforce the front 6-8" (kinda like morrison bows). He feels so bad about the break, he is sending me a 70" yew stave, snake skins, and elk hoof to put tips on my new osage bow.
And I am not saying he is a good guy because he is sending me free stuff, but he gave me some excellent tips on my bowmaking

It's hard to get folks any better, more friendly or more helpful than the traditional crowd, but I do believe the primitive crowd has done it.
