The plan was to try to match the thickness and profile of one of my store bought guitars, with the caveat being it had would have to leave at least 5mm remaining under the PBG neck’s truss rod cavity. From measurements and eyeballing it appeared I’d have ~5mm left, so I made my profile templates and went for it.

I didn’t take any final thickness measurements at the time, and it’s a little tougher to get accurate values now that it’s finished and strung so these may not be exact:

1st fret: 21.7mm (0.85”)
12th fret: 22.93mm (0.903”)
