Strap Button Dowel Repair Drill Guide
A hand-held guide block (80 x 32 x 24 mm) for fixing a stripped guitar or ukulele strap-button hole. Its three vertical bores share the same sight notches, so the bit stays on the original centre at every step: drill out with the 6.3 or 8.3 mm bore, glue in a 6 or 8 mm hardwood dowel, then drill a new screw pilot through the 3.4 mm bore with a 3 mm bit. Grooves under each bore clear chips, and countersunk lead-ins make it easy to start the bit.
