Salvagable? Sinew/superglue patch on this crack?
« on: November 07, 2015, 03:51:16 pm »
I was just about there, 40#@27" when I heard the crackle.  Looks like this Ipe, even with a cable backing, is starting to crack on the side.  The crack is maybe an inch and a half long, and it's starting to lift a splinter on the back under the brown paper backing.  Do you guys think this one is a candidate for filling with superglue and wrapping with artificial sinew?

here are a few more pics, I have it drawn to 24" in that pic, I didn't want to draw it further without a patch if it's patchable.

What happens if you put bridges where I put the arrows? I know that's not answering your question but if that's where the crack is some bridges might take some tension off the back.

one more pic, I saw the same thing, looked real hingy out of the handle, but when I draw a circle on it, it looks a lot better.  It does bend through the handle.  I think the shadows are playing tricks on the view of it.

I can try it.  I was wondering if putting more bridges on there to raise the cable would help some.  The cable is right along the back right there.

I think that if the cable is right on the wood it's not doing much. But take that with a grain of salt. I've never even seen a cable bow let alone made one.
