I have the 33mm block, the smallest one. But even with that it looks like it's going to cut it pretty close unless the bridge sits much higher than I expect. So the embedded cover most likely isn't happening. Might try a partial embed with a taper, and have the inside of the cover cut out so it's about the depth a flat cover would be. That might look and function pretty well, assuming my brother has the tools to do it.

Ended up sanding the neck a touch so it fits somewhat better. Still ridiculously tight, actually damaged the heel slightly and have to glue a tiny piece that splintered. Can clearly feel where the wood is compressed from being in the neck pocket, might take a smidgen more off.

Letting that glue dry stalled my neck grain filling. Was checking where the neck needed to sit for the appropriate scale length. I assume with the locking nut, you still measure from the very front of the nut.
