Well it's time for a couple more updates, but I'll start with the one I should have posted a month ago (oops).
The first thing I did was remove the nut, then shape the headstock. I also took the opportunity to test fit the Grover locking tuners... but I think I'll need to find some different hardware as they look a little weird.

After that, it was time to shape the nut and file it out for the strings. I used 13 - 56 StewMac nut files for this, but I feel the bottom E will need to be a heavier gauge to tune to where I want to on this scale length. It's nowhere near perfect, but that's okay: I'm using this as a learning experience, as I'll try to transfer the skills here to a replacement Tusq nut down the road a little.

But now onto the newer progress... finishing!
