Sperzel Single-Pin Drill Jig - Guitar Tuner Peg Install Mounting Fixture

We are proud to offer this anodized aluminum drill fixture to help you mount your new Sperzel tuning machines as precisely and as easily as possible.

To use it, simply place the drill fixture in the hole of the headstock for the Sperzel tuning machine and align the fixture to be parallel with the edge of the headstock or inline with each other. Next use a threaded pushing to hold the drill fixture in place while you drill a 5/32" hole 3/16" deep.

The last step is to remove the fixture and repeat the above until all mounting pin holes are drilled.
