The anodized aluminum Tuner Pin Drill Jig lets you drill accurately located pin holes in the back of a guitar headstock, to accommodate the alignment pins found on many modern enclosed tuning machines. These tuners don't use the traditional exposed tuner mounting screw, but rather a hidden pin on the underside of the tuner housing.
It keeps your hand drill perpendicular for accuracy, and works for left or right-side tuners. You can position single-pin Schaller tuners, two-pin Schallers, one-pin Sperzels, and Fender locking tuners. The jig fits into the peghole with a self-centering bushing and thumbscrew for quick and easy attachment. Instructions included.
This jig is designed for use with a No. 38 (.101") drill bit. Measure the height of the alignment pins on your tuners and drill the holes to the appropriate depth.
