Well I am happy to say the trilam lives! I had to do some work on it. First I reattached the broken osage with superglue. Then I sanded off all the old glue from the osage and the horn, and I flattened the surface of the horn, removing the waves. then I glued the maple onto the top of the horn with superglue. The tip I glued with a good quality epoxy and wrapped it and let it dry for three days. A little sanding and shaping eliminated the slight slip (1/64" or so) in the tip on glue up.
I had also planned to put a leather handle on it because I like they way it feels when I shoot. But when I got the yarn off and had re-worked the grip a little to fit my hand, I could see the figuring starting to appear in the maple, and I couldn't bring myself to cover it back up. So I left the handle naked.
reworking the tip and the grip left gaps in the finish, so I stripped the rest of it off and refinished with 8 coats of tung oil. Here are the results
