I am going to try this again. This is a little jig I made to drill holes for Grover open back tuners.

Here's the explanation from the other thread that didn't work.

Iwas reading a thread on the "other" forum about how to step drill tuner holes for Grover Sta-Tite open back tuners. Having access to a metal lathe at work, I came up with this little jig that works very well. It is basically a piece of 1 1/4" steel rod with a 1/4" hole drilled in the center. I milled a little "nubby" on one end to press fit into an 11/32" hole in the headstock.
Drilled the tuner holes with the 11/32 bit to the proper depth for the bushings.
Stuck the little round thingy in one of the holes and used it for a drill guide for the 1/4" drill bit.
Result: Perfectly centered holes.

I use this. I know it says in the catalog that it is for the Waverly tuners but it works just fine for the Grover tuners as well.

John, that's what made me think of doing this. This one was a heck of a lot cheaper . It took about 5 minutes to make and was free. Just an old cheapskate at heart.

Good point. I don't see why it couldn't be made out of some kind of hardwood though.

Rock hard maple lasts for awhile on this type of things, but the center gets "wallered out" after so long.
