This is what I was thinking. In my work with wood (such as building/repairing slingshots) in the past, to fix a damaged fork, and to make it as strong or stronger than the original wood, I would drill it, pin it and use 2-part epoxy for the repair, likely with a little bit of wood dust (from sanding, the same color as the wood being repaired) mixed in the epoxy. Seemed that type of repair held up best under stress. But what @jbett98 recommending regarding drilling and pinning is exactly what I was going to recommend. It will make for a very strong repair.
