These jigs align your hand drill correctly for 1/4" pegholes, so your tuners will be accurately aligned and spaced. Use them for new instruments, or to correct tuning problems caused by misaligned pegholes.

Made of machined steel for a lifetime of use and specially coated to resist corrosion. Each 1" x 1" jig includes two steel transfer pins, two steel alignment pins and instructions.
The jigs are for use with a 1/4"-diameter bit. To enlarger pegholes, or to counterboring for bushings, remove the jig after drilling, and use a Peghead Bushing Reamer.
