A unique jig that aligns your hand drill for accurate tuning machine mounting pin holes
Tuner Pin Drill Jig
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.
