StewMac Guitar Repair Magnet Set

Attractive solutions to tricky repair jobs! Make custom repair cauls, magnetize pickups, and more. See the video for tips!

As guitar repairman Dan Erlewine has discovered, "magnets are tools and they have lots of uses!" Repair shops are constantly finding inventive new ways to use them.

For example, magnets can be attached to (or inlaid in) clamping cauls for easy alignment with steel clamp jaws—a great help when aligning patches for repairing cracks, or when regluing a bridge.

An exterior magnet will move a second magnet inside a guitar where your arm can't reach: wrap the inner one in a damp cloth to clean glue squeeze-out, or attach self-adhesive sandpaper to remove dried glue.

For building or repairing guitar pickups, you can use a 1" pair to magnetize a pickup or change its polarity. Single-coil Kit Instructions tell you how.

This versatile little kit contains two 1/2" (12.70mm) and two 1" (25.40mm) round nickel-plated magnets. Each is 1/8" (3.18mm) thick, with a center mounting hole that's countersunk on both sides for handy attachment to clamping cauls.

Also included are two Magnet Handles that make picking up, positioning and separating these powerful magnets a whole lot easier. Based on an idea by Al Rorick in our R&D shop, they're made of knurled brass, 1-3/16" long, with attachment screw. Each handle holds one or two magnets, as needed.

Here's a tip: Always use protective paper on the outside of a guitar when sliding a magnet over it.

Warning: These are seriously strong magnets, made of rare earth neodymium boride. The Guinness Book of Records lists this as the world's most magnetic substance, ten times stronger than the ceramic magnets used in modern loudspeakers. These magnets can degauss, magnetize or repolarize any ferrous or magnetic material, including guitar pickups! Keep them away from magnetic storage media such as computer discs, audio and videotapes, as well as pacemakers, computers, CRTs, TVs and watches.

KEEP OUT OF REACH OF CHILDREN. If magnets are swallowed, they can attach to each other and cause internal injury.


Trade Secrets!

How would you reach inside a guitar to do this gluing?

Dan Erlewine's got a puzzle on his hands: this guitar's center strip fell out along with the braces. These parts are meant to be glued BEFORE the guitar is assembled. How do you reach inside to do this on a completed guitar?

Helpful repair magnet gizmo, and 1970s Earthwood Bass!

Ouch! Ouch! Ouch! These repair magnets snapped together with a CLACK!, drawing blood from Dan Erlewine's finger just as he was about to show his gizmo for avoiding pinched fingers and separating stacked magnets! Also, Dan explains a radical bracing change on an original Earthwood acoustic bass guitar.

Handy little magnets all around

By
(Customer's Reviews)


I bought those for magnetizing pickup polepieces. I built a sliding jig, like a small drawer, to be able to slip the assembled pickup between the magnets, and it works like a wonder. In quantities, they should serve as clamps (Specially for acoustic guitar repairs). They can be stacked for concentrating "power" in the same spot. It'd be nice to have clear markings for south and north in the pieces.

This product is great. I use the magnets for all kinds of workshop tasks. Not just guitar building.

Terrific, though plating peels off rather quickly. 

By
(Customer's Reviews)


They're great for cleating, gluing braces, aligning and gluing cracks -- amazingly effective and a cinch to use if you get 'em WITH the handles! However, the chromium plating began peeling on mine after several uses, leaving exposed edges. These can scratch the finish of the guitar if you're not careful! I smooth-sanded the magnet to get rid of all particles of the chromium, and I always put tape or wax paper between the finish and the magnet.
