  Not being a smart alleck here but nothing else could have happened the way you had it supported. I would glue it inside the crack and press it back together and it shoud be fine.

Your clamps need to be inline or above the support blocks, or you will be applying bending stresses where you don't want them to be.
As Badger noted.... glue and clamp and you should be fine......  I had a finished recurve bow break at that same point when the string slipped off one of the tips during a shot.  Dry fire!  :(  I super glued and clamped it, then wrapped with sinew and it has held for about 700 shots and still going strong.

Im not sold on gluing and clamping it until I see that crack better. Looks almost like the crack extends to the back after a hard left at the knot?

The crack does go beyond the knot a bit

Yeah me either.  That scares me.  A break in the handle can be explosive.  I would go ahead and glue it and see, but be afraid.

That looks like a lot of reflex coming out of fades on your caul.  Mine has a gentle reflex in the center and increases as it goes out the limbs.

Can i work that handle down and follow the ring its on? Than possibly make my first bend thru the handle bow?

The crack follws the ring, it doesnt go towards the back of the bow

If your dead set on it being a bow here is the one and only way Id do it if it where mine.

Id totally saturate that crack with Loctite Professional super glue, no others, and clamp it for a few hours. Then Id wrap 2" beyond the crack end each way with some no stretch, high strength, small diameter braid. Fishing line would work. Then Id saturate that entire wrap in the same glue. It would be ugly'ish. but it wont ever come apart.

I'm with pearlie and outlaw, You might want less reflex near the handle more toward the tips, and the last time something like this happened (molle lever, tried to push the reflex into the fade which was dumb ::) ) loctite-pro and a sinew wrap saved my butt.

I would super glue and clamp as Badger said, you are pulling it tighter as you string and draw, it should be fine, seen a lot that happened to. :) It will almost always happen if they have a hump in the handle. :)The wrap sure won't hurt but I don't think it is necessary.  :)

  This is correct: the old addage about making the bow the stave wants to become applies!  :-)   I have done the same thing, though.    If I have much natural deflex in a stave, I turn it into a deflex recurve/reflex. 

If you want to get creative and have any tools, you could even saw out the crack and square it up, then glue in a fitted splint, and work it in to the rest of the handle (assuming the back is very intact).  Cut it at a diagonal so you don't have one weak spot across.

Epoxy , epoxy, epoxy forget superglue it's just not meant for this application. Superglue is brittle when cured and this area will be subject to a tiny bit of bending and a lot of shear.
Get some good epoxy and heat it gently it will flow just like thin superglue, also a little gentle flexing , letting gravity help will get plenty of glue in there no problem.
If glued well why would it NOT hold? Think about what forces are acting on it.
