Tonight I was working on a new bow and on the way to 24", this happened.........

And a view down the limb

Can it be fixed?
This bow was a gift from Walt and I would sure like it to become a shooter!
Thanks for the help,

Yep it can be fixed, I had that happen on my first snakey bow. Splintered in the same spot, I super glued the crack and sinew wrapped it, a good 2" either side, it held. That area, where it snakes and dips can be difficult.
-
You had a run out on a snaky grain place. You really have to be diligent in following the grain around a snake. I can see the error in following the grain by looking at the picture.
I learned the hard way about not perfectly following the grain in a snake. Actually I learned the same lesson 4 or 5 times before I paid closer attention to even the slightest grain undulation.

General question. How do you continue to tiller if the area is sinew/thread wrapped. I have fixed a finished bow doing that but can't see how you can properly finish the tillering with the repair in the way.
Sorry to hijack the thread.
-
Before I wrap, I like to round the area pretty good and then you just end up tillering it as normal and hope it's not too stiff. Generally splinters happen after you have it bending pretty good. They create an inherently weaker spot there anyway so you are really matching up the non-wrapped areas with the weaker wrapped areas. I usually only wrap for 1" on either side of the splintered area to minimize the portion of the limb I won't be able to get to any longer.

Razorback,
Thanks for askin'. That was my next questions, I have 2 more inches to go on the tillering tree, need to get it tillered to 26", and the bow still needs to loose a bit of weight. So what is the correct way to wrap a bow with sinew, how does one go about finishing the tillering process once it is wrapped, and how will a finish like True Oil effect the sinew.
Thanks,
-
I did as John said above, you can see the spot on this bow didn't turn out too ugly. Tru-oil will cover sinew just fine.

After gluing try using a temporary cordage/thread wrap until you have your bow ready to finish. You can then remove the wrap to make adjustments as needed. This can be a slow process sometimes but I think you'll get a better performing bow.

Thanks for all the help, but I still have a few questions......
I ordered some sinew and hide glue today from Kustom King. Is there a correct way to put it on? Is there a need or a reason to lay strips the length of the limb before wrapping it? And what holds it in place while it is drying, do you wrap over the ends simular to when you are serving a string, or does the glue hold it in place? How tight does it need to be wrapped?
Thanks for all the help!
-
I would use the Tite-bond waterproof glue for the sinew wrap. You can use the hide glue if you like but be sure to use a finish over it. No need as far as I can see to lay down the sinew lengthwise before wrapping. Personally, I think thread wraps looks much better than sinew wraps. Just my opinion though.
You just wet/soak the sinew threads (damp dry or squeegee the water out) before coating them with hide glue, then wrap. Or you can coat the area that's to be wrapped and simply wrap with wet sinew. Add a little hide glue over that. If you use the TB glue just coat the area to be wrapped and apply the moistened sinew and let dry. Brush on several coats (let dry between coats) of the TB glue and you're good to go. You don't need to bind sinew tight like thread because is shrinks as it drys.

Yeah, like Art says, thread or serving material wraps are great. I have a few bows with f.f. serving wrap then saturate with a good brand of super glue like Loctite. Good luck, and let us know how it turns out. Steve
