Sorry haven't been posting but I've done quite a fair bit of work.
After the glue dried, I had to clean up the laminates. For the headstock, I used my Shinto rasp to level the mahogany pieces, using the maple piece as the guide, since I had already shaped it to the correct size. I also used my orbital sander and a chisel to get the laminates flat.
I could've built a jig to route it flat but I didn't have enough material.
