I just got my Hipshot D-Tuner for a Status-Graphite S-2, but am having a little trouble installing it. The screw that mounts the unit to the back of the headstock is a little bigger than the screw that was there holding the tuner in place. I originally tried to put the new screw in and see if it would bite into the graphite and hold, but no luck. I then did what I'd do with wood in this situation - I drilled the hole out just a bit, hoping that the new screw would have room to work, and would thread itself into the new hole. No luck again - the screw head i stripped, so I'm guessing the hole still is too small... My question is this: Is there a certain way I need to drill this hole to make the screw thread into it? I don't want to drill a hole *too big* and have the screw not lock in (I can't put the original tuner back, since the hole is a little too big, and not threaded anymore.) I'm sitting here with a 3 string bass, so I look forward to any advice you could give.
