Maybe I'm a bad craftsman, but here's what happened to my MOAB.
The leftover material in the riser, after cutting the half-moon for the hinge, did not have the strength in the belly to handle the compression.
The screw holes were aligned with the grain of the bocote, which created a weak zone. Bocote is a soft wood anyway.
I tried to recess the hinge, which took away valuable laminations in the back to handle the stress.
It turns out that the bow's grip had been built up with fiberglass, the thickness of which I did not see until after I had cut the bow in two. So there wasn't enough wood to handle the stress.
It just was not meant to happen and I lost an expensive beautiful bow. Bows and hacksaws are a bad combination, at least for me.
You can chalk it up to my bad craftsmanship, but I thought I had followed the instructions to the letter. Others obviously have done fine with theirs, but be prepared.
And, after all that, I have since purchased other 2 pc bows made during construction by the bowyer, only to realize that I don't use the take down very much anyway. I just keep it strung and use a tube for transport.
Bows have a LOT of stress at full draw!! My hat off to any successful bowyers or hinge installers!
