Dang bro, that stinks!!
Let the bowyer take a look, here is one I fixed!! LOL
Had a mule wreck in CO and cracked my bow down from the side plate into the handle area,I'm tryin to salvage her quickly so I can hunt with er this fall......
The crack(hilited with erasable marker)

1/8" brass rod,sanded rough and riser drilled to fit....

Smooth on applied,tape on backside so it can't run out,puddled down into the holes around the rod.....

May have caused trouble later drilling those holes in a line,surley glue and brass are as strong as wood,what do ya think?
Stay tuned......
