Thanks! Yeah, I think I see a mishmash of flat and Phillips, especially on those early prototypes. Through a couple heavily worn gold screws in with the chrome ones.The attention to detail still amazes me. Like flathead screws, definitely original, but a pain to take out and put in. I considered it for my 52' style Telecaster but but I figured that I mess with my instruments to much to strip it out and never be able to replace say the pickups.
A violin reamer works better than the General hardware reamer for doing tuner bushings. It has less taper which matches the bushing better.Here I experimented with the weird painted truss plug you see on some '54s (the first pic is a vintage example). I ultimately decided against it. I reamed the tuner holes so that the bushings needed just a push with the thumb to seat. Any tighter than that and you risk cracking the headstock. Marked and drilled for the tiny mounting screws, and installed. A ruler works great for lining up the tuners.

Yeah, they make great, highly specialized tools for the professional luthier.A violin reamer works better than the General hardware reamer for doing tuner bushings. It has less taper which matches the bushing better.
StewMac also sells a bushing reamer that goes into the drill that sizes them perfectly every time.
