“Hello! My first-ever order arrived today. I had ordered some wood items and they are GORGEOUS! Smooth, perfectly flat!, and the woods themselves - with each one I pulled out, I just kept saying, WOW!, *WOW*!!!, over and over. And thank you so much for the beautiful piece of East Indian Rosewood - it was described as "2nd grade" I believe, and I asked for a reddish color if possible, and I think this piece is absolutely stunning! These really exceeded my expectations! 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.
