Okay – bigger hole at the back, held in with black hex bolts, because I like black hex-bolts.

It works pretty well… looks ok, doesn’t rattle.

I’ll use this one for the first guitar… Guitar #1… although I’m actually making 2 at the same time. For the next one though, I’ll try to make something with a completely removable front. Even the larger hole doesn’t provide enough axis, and if you’ve got a completely removable front, you can change fronts.
