Thanks, I was thinking it would be something like that.
I learned an easy trick for this back in my days on the road: you hang the end of a gun type solder iron on the tuner & when it heats up , you press the tuner button on, done. make sure you drill a smaller pilot hole in the new tuner button, this makes it easier to Center & make sure to take the tuner off the guitar before you add heat?
Great idea. Will it work for wood?
As long as it’s not glaring hot, it should. The metal will cool down rapidly if it’s not too hot? Another way I’ve seen, is to do two halves. One half has a flat channel & the other has a round channel. When they’re glued together, they make the perfect shape?
