Would it be safe to shoot this bow if filled with all Loc tite 420? It is definitely a separation in the Osage as you can almost get a fingernail under it, but doesn’t run all the way across the belly. The boyer said to make a wall hanger out of it. I hate to give up on it. If it does blow, will the bamboo just splinter and collapse or will it become two piece propeller?

This is bamboo backed Osage

it's a crysal/over compressed wood...some last a long time, some just get worse. super glue and a sinew wrap might give it a little more life. Torges use to use a spindle sander to remove a plug, and then replace it with a new piece.

The real issue is why it happened. Osage doesn't do that.

Sad to see a beautiful wood bow break of with cracks like that, it is like losing a good buddy.

I have a different belly issue, needing to eat less and do more situps

I agree, it looks more like a tension failure than compression. You didn't try to bend it back the other way because the limb was hinging there (getting weak), or bend it the opposite way after a fret/chrysal showed up did ya?

It looks like the limb is a little more narrow right there in that area too.

Nope, all I ever did was string it push/pull and shoot it. The first bow I bought from this boyer failed on the back. It was a little different and this one was its replacement; supposed to be an improved model. . I remember reading about Deans repair method, might give that a shot.

Is Osage prone to crystal? Or is this backing too thick thus overpowering the belly? Or bad wood?

bad tiller or too thick on the bamboo is my guess,,or combo of both,, that is a hard fix,,

No, osage isn't generally prone to compression issues.

The backing is a little thicker than I like it, but I doubt it would have been an issue if everything else was fine. There may have been an issue in the wood itself, hard to say, or it was tillered to flex too much in that area... or a combination of things.

I've used the patch Dean Torges advocated with success, but wouldn't declare it a suitable option without studying the bow in detail.

Never been whacked so not skeered. If it were mine I would CA glue it and maybe add a thin coat of epoxy. Wrap it tight from 2" above to 2" below with strong/bow string, then coat the wrap with a good clear wood glue. Do the other limb exactly the same for looks and performance then continue to play. >>>----> Ken

I have a bunch of sinew, I’m not short on bows, so I think I’ll do the ca. and wrap it. At least if it blows it should stay in one piece. Thanks for all the suggestions

if we could see the bow at full draw, it would reveal some things about the tiller,,

Never thought to try that.

Oops,Sorry Patrick wasn’t intentionally ignoring your request! Here you go.

I like your play room and we have a near match of that dog.The sinew will be great.Be sure to match both limbs.>>>---->Ken

When I first looked at the full draw pic. I thought ‘levers’; doesn’t look to me like outer third is doing much. And the raised Osage appears right at the spot it stops working. Definitely going to sinew it and see how long it’ll last.

Kenneth, she is the worlds most docile dog. Best kids dog, but sheds terrible. Amazing how much hair she produces in a day lol.

Thanks all for the insights.

Poor tiller, no other reason. That bow has very, very little reflex and should have a much more round appearance at draw. That area the ribbon on is hinging, hence the compression fracture. I would either hang it up or fix the tiller and and wear safety glasses each shot. Wraps wont do anything for compression failures. They are good for one thing only, fixing splinters caused in tension on the back.

Thanks Pearl, I said the same, they just didn’t get it bending. I bought it before I had a tillering tree, but I’d never have thought to put it on it anyway. As for the wrap I was just thinking safety, not helping the bow, but the more I think on it maybe I’ll just shoot my other bows and retire it for good.

Sorry to be so blunt, its just who I am. I don't beat around bushes, unless I'm bunny hunting :)

No problem. I put this up to get possible fixes and learn. Never occurred to me to take profile pic. If I had before posting it would have been self explanatory. I’ve messed with enough board bows (and followed along with folks like yourself on different sites) to have a rudimentary idea of what arc to look for and this isn’t it lol.

Bamboo can quickly over power osage in BBO. One minor flaw in the wood, or a slight hinge in tiller and they will crush the belly post haste. Bamboo too thick is another factor that may have impacted here. Almost cannot get the boo too thin, but too thick comes easy and often. Fast, fun, and sexy, but fraught with pitfalls and easy failure.

Chrysals happen when bows bend too much in one spot. To fix, leave that area alone and remove wood from above and below the area. Retiller the other limb to match. Jawge

I think it is a tension crack from reflexing the bow when it wasn't quite able to take the bend, if this is the case it should be fine to shoot. It really doesn't look like a compression fracture. The area where I see this is not in the hard bending area, it is in the area he reflexed. I think you could shoot it and enjoy.
