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.

Guitar Repair Magnet Set includes
  • Two 1" magnets
  • Two 1/2" magnets
  • Two magnet handles
StewMac Magnetic Mirror Set includes
  • Mirror with articulating arm with handle
  • Two 1" magnets
  • Extra magnet handle

Our magnets are custom made with a center mounting hole that's countersunk on both sides, handy for attaching clamping cauls and our specially made magnet handles. Nickel-plated magnets are 1/8" (3.18mm) thick and come in two sizes: 1/2" (12.70mm) and 1" (25.40mm) diameter.

Magnet Handles 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.

Mirror is 1-5/8" x 2-1/2" (41.28mm x 63.50mm), attached to an articulating arm with brass handle to fit our magnets.

Tech Tip: Use a thin pad of felt or leather under the exterior magnet to protect delicate finishes.

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.

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.

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?

Not only for pickups!

I use them to glue some pieces. They are so powerful that they can support small pieces of wood in place.

It Saves Our Lungs!

i got the 1" magnet to keep the steelwool's debris to get into my lungs, and it works great! you can flip it inside the steelwool ball or right in the nearby of the frets you're polishing, no matter, but get one and your lungs will thank you.

These magnets make crack repairs a much easier job. And they are great at blocking glued up parts from sliding away.

Genius Idea

(Customer's Reviews) Sunday, December 12, 2010

Recently fixed a completely separated back seam on a Taylor 314 with these little beauties. Not sure how I would have done it otherwise. My customer is VERY happy!

A strong attraction..

By David A. Wiseman from Spruce Pine, NC
(Customer's Reviews) Thursday, November 18, 2010

These are the perfect tools for small and hard to access clamping jobs.

These are not toys. They will shatter if allowed to "slam" together. (Thanks, Stew-Mac for a speedy replacement.)
