Fill w/ CA and slap an "underlay" on there?  :-\

It's worked for me in very similar situations.

Best of luck!  )P(

Is that some sapwood on the back?
How thick is it in the bend?
Does the crack go through the limb?

yes there's one ring of sapwood i left on it for looks
its maybe 9/16-5/8 of a inch thick at the moment in hind sight i should have brought it closer to 1/2 inch
and yes the crack go's all the way through it but not any farther down the limb

Dylan, I agree with upstate. Fill it with super glue. You mar eliminate it or most of it when you thin the tips. If not add an underlay(overlay) and it should be OK.

My gut tells me it'll work. But I think I'd give it a wrap of sinew. It's hard to tell but looks like it maybe goes out end of bow? Maybe that's a pencil mark. It seems like a static should be ok.

Another vote for underlay / overlay

Overlays can be very attractive, I have cracked statics bending them and put overlays on all the curves  to make up wood after for filing the cracks out and over thinning the limbs.

I would thin the tips, with that large of a crack I would use epoxy to fill and add overlays to both the back and belly side of the tips.  Epoxy fills voids much better than super glue.   Super glue is best for thin cracks JMO

What about a foaming style glue  ??? I’ve misplaced my CA but I have a bottle of foaming polyurethane glue and some 5min epoxy

No to the foaming glue. 5 min epoxy is not as good as a longer cure epoxy. If possible, get the best glue for the job. Either good superglue like loctite 420 or gorilla. Or a good epoxy that cures in 24 hrs. Personally i would use epoxy if the crack is wide.

Thin super glue would be best because it will get down into the small cracks. Time to get a new bottle of super glue.

alright i'll run by the hardware store and get some more CA (i think i might have left my old one up at Marshall  :()
i'll also thin the tip down some and see if putting a clamp on the tip might close up the crack some.

Looks like the crack goes right through. I would do what DBar suggests.  Epoxy will flow into thin cracks if you warm it.    Tape off  the belly side and pour it in the top.  After it cures flatten and double up the overlays on back and belly.
