well, i snuck some glue under that little crack, and a couple days later I got back to work on the thing.  I narrowed the entire bow, handle to tip, and then sanded a fair bit of the inside.  Still lifted though:  that little crack.
So, i am following Pat B's earlier advice:  I have ground up 3 lams (popsicle sticks, really) to cover the handle and thicken it up a bit.  1 is of hickory, to contrast the belly; and 2 are of yew, 1 for the back, and 1 for the bellly.  WE'll see...it might not be very pretty!  but i can always stain it.  I now have an abundance of pacific yew, whereas i am running low on osage and what i do have is spoken for.
we'll see....
