I bought an inexpensive vintage Kluson set of machine heads from China on eBay a couple of years ago and they've been sitting in storage waiting for me to put onto one of the Telecasters I'm veeery slooooowly putting together. I went to install today and I realize that one of them has no string hole (the bottom one... it's not just turned sideways... there's no hole at all). I guess they missed that one when drilling. I know I should probably just replace the set, but I have them and the tools are right there. Finish aesthetics don't have to be perfect -- it's a pine-caster and it's already rough. It's intended to be a player not a looker. It looks like a 5/64" bit fits with slight twisting so that's about the right size. You think I can clamp it down somehow on the drill press and blast my own hole? Maybe drill a smaller pilot hole first? Or put it into a vice and use a dremel? I never have much luck drilling straight through round/cylinder object, but I might as well try. I have no idea how hard this metal is. Alternately, I guess I could slot it with a cut-off wheel. Relic.
