New Yew in progress
AH:
Well, life got in the way of uploading pictures earlier.
Still trying to figure out a way to get epoxy down the wind shake, it seems to go throught he entire limb :(

Yikes. That doesn't look very nice.
On the plus side, that might just end up being removed as you tiller, but you're gonna want to secure it first. I'd go for superglue instead of epoxy on that. Clamp the bow so it's side-up, pour as much superglue as you can into the crack, all the way down, and make sure it's leaking out the other side as well. Then clamp the whole thing up with a few clamps or a long rubber band to maintain pressure. Let it go off, then see what you've got. It needs to sound good - tap the surrounding wood with a fingernail and take note of the sound. Then tap the glued up area and compare. If it sounds like something's moving when you tap it, or its thin and papery sounding, redo all the glue again.
If a large area like that isn't solid it may end up pulling away from the belly as the bow bends. Not good.
Your other option is to just plough through it until you hit solid wood, then make the best bow possible out of what remains.
If you go with option 2, leave the sapwood at the thickness it is already. If you manage to secure it with glue and it feels and looks solid, get that sapwood down to a sensible thickness and carry on!
Del the cat:
Epoxy won't do anything, it needs a good quality low viscosity cyanoacrylate (superglue) which will go in by capillary action.
Looking good.

ceolith:
here in germany we call this condition: Kernholzabspaltung (Corewoodsecession). there is a fault in the growth of the yew. usually you should not use such a stave for a bow.
i know, it's your only one etc...
and IF you wish to glue these peaces together, then you have to remove the remains from the cambium. it's the fluffy stuff which you can see against the light. to avoid unpleasant shear forces, you should use EA-40® Transparent Laminating Epoxy Adhesive.
cyanoacrylate (superglue) is not flexible enough!
