For classical or steel-string pegholes. This swiveling aluminum jig maintains 35mm (1-3/8") hole spacing for string posts or rollers.
Hardened bushings keep the holes straight, perfectly spaced and centered — you can use a hand drill!
Clamp the jig on any peghead from 1/2" to 1" thick. Use the supplied 13/32" (10.32mm) bit for classical machines, or the supplied bushings and letter "G" bit (0.261", 6.63mm) for steel-string tuners.
