Tuner Pin Drill Jig

I love the tool, except it has some issues like requiring a standard spacing and the holding screw clamping is not as positive as I would like. They are great for 19 out of 20 guitars, and most tuning machines. Some machines I had to make my own version of this. I used 3/8" Lexan with a bolt through the tuner peg hole to hold it down. I added some shims to size the tuner peg hole. The shims worked great with the Stewmac tool too! They are just sheet aluminum bent around a dowel and another around the inside shim(s). They snug the bolt up in the hole on center. Using 2 or 3 of these jigs along a straight edge makes the work more precise, faster, and easier. Until I really get bored, or need to, I plan on using these and not making my own from see through Lexan for some time, but the Lexan did make a nice jig too. I would knock off a star for price and some fiddlieness, but the time it takes to make one of these tools more or less justifies the price. Still it could be improved upon, but what can't!

Nice and precise tool.

I use it at least once a week. Very easy to use. You can't go wrong purchasing this tool. A must have for the busy repair shop.

Bought this after I botched the initial install of my new tuners.

Well worth the money - the schallers were installed in about 20 minutes with the jig. Going to install some sperzels on a friends guitar this weekend as well.

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.
