I want to express my deepest gratitude to the team at LMII. When I started making guitars 26 years ago, my first guitar was made from wood that I ordered from the LMI catalog (there was no internet back then). Since then, the team at LMI has been nothing short of excellent! The products and services are second to none. My only regret is that I waited 26 years to say...THANK YOU!
This classical 3-hole tuner drill jig by John Gilbert makes easy work of an exacting task. The 13/32" holes are industry standard, as is the 70mm (1.378") post hole spacing. For alignment purposes, lines are scribed center to the hole on the outside of the jig. A steel plate can be clamped to and extend out from the head, to act as a stop. Between this steel plate and the jig you may need to add shim stock to center the holes (see photo). If necessary, the jig can be used as a single guide by simply moving it from hole to hole.
Solidly made of cold-rolled steel and drill bushings, it measures: 3 7/8" x 1 1/2" x 3/4"
Use the 13/32" drill bit, HSSJ1332, with this jig.
