Tuner Pin Drill Jig

Being a new custom guitar builder I wanted not only a much more easy way to do things but being spot on is most important to me. This little jig is one of the best tools that I would put in my "can't do without" list and proves to have value. If your doing one guitar or even plugin a headstock from an old set of tunners, this is indeed valuable.

I used the Tuner Pin Drill to install two-pin locking Tuners on a new neck. It worked perfectly. I positioned the jig by placing a small square across the headstock and pushing the back of the jig against it. It was fast and effective.

It can be a bit fussy at first, but once you get the feel for setting the jig up, it does an excellent job of locating and helping drill the holes.

Works OK. The jig wobbles a bit if the mounting screw isn't super tight. Next time I'll use a piece of 1x2 and 2 wood clamps to hold the jig parallel to the neck edge. That should cure the wobble issue.

This tool is so good to have in the workshop. We use a lot of sperzels in our workshop so this tool is a must have. But like a lot of other (clever) folks on here we bought more than one. Why? Because on a 3 a side headstock you will find it way easier to line up heads if you do them in pairs(e/e, a/b and d/g) using a straight edge or ruler to guide you - so simple!


If you are doing a 6 in line headstock use 3 of these in alternate holes (E, D & B and then switch around and do A, G & E) - again using a straight edge to line them up . The job is about 70% quicker to do and will save time money and heartache that way. Also we fitted an exactly sized drill bit in one of the Stanley "snappy" holders to make it super quick to chuck in the drill . we fitted a depth stop made of heatshrink tubing - although we put a bit of masking tape on it in this picture.

This little gadget works great.

I have used it on my clients guitars and my own with precision results every time.

Just use a square to line it up and a hand drill (eggbeater) you don't want or need a power drill for this.

Highly recommended for any guitar workshop.

I agree with the other reviewers. This is a very handy tool. StewMac might consider offering a small engineers square, 3 or 4 inch should be good, that's what I use to line it up.

I've used this jig once so far, but the results were excellent. I had a vintage-drilled Strat neck and a set of Fender-Schaller locking tuners. This jig was a big time saver. The conical centering piece worked well even with my hand-reamed holes. The pin spacing proved to be dead accurate. One caveat: torque the jig down good and tight and work slowly. The jig will want to rotate as you drill. I like simple, well-made tools. And this fits the bill.

This is a fantastic tool, that saves time, trouble, and heartache. It's made a complicated life a little simpler. And for that I thank it!

This jig makes life much easier! Very simple, easy to use and well worth the money!
