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?

Repairs just got way easier. Cracks, clamping, sanding places that are normally way out of reach inside the body. Don't know how I did without these things.

Good kit

I could have bought cheaper rare-earth magnets from a craft store but these had the convenience of handle-holes with brass handles. It makes controlling the strong magnets much easier. I used them to charge-up the pickup I wound.
Worth it!

Little magnets, BIG tool

By Don Noonan from Easley, SC

Had a crack in the lower bout. Had seen these magnet on StewMac and just thought they wouldn't work. Posed question on a forum and someone suggested them so what went ahead and purchased them thinking they would not work. Pressed gingerly on the top to open crease underneath and squeezed in some glue with my finger. Using wax paper between magnet and wood, placed them over the crack. Let it dry over night and to my amazement, when I removed the magnets and wax paper, the crack was gone! Can't post before pic but here is after. The crack was just to the right of the magnet where the light reflection is. The before pic has the reflection split and is quite obvious there is a crack. These magnets are just what the 'doctor' ordered. Thanks, StewMac!

Always dounbted the claims of this little tool BUT, I had a crack in the top in the extreme lower bout. Couldn't think of anyway to fix it. Got some ideas off a forum and with nothing better, the magnet kit was my only option. Pressed gingerly on the top to open the crack on the inside, pressed some glue up into the opening, covered top and bottom with wax paper, put the magnets to work and to my amazment, when I removed the magnets, the repair was completed with no signs of a crack or ripple where the crack once was. Fantastic little tool that I plan to use more often. It works!

Good magnets, great handles.

Overall I'm pleased with magnets and handle. Handle is the usual SM quality and is very... handy. I have since found another online supplier for the same magnets at 1/3 to 1/4 the SM price. In future I will buy the handles here but magnets elsewhere.

Love these handles!

I like these magnet handles for moving the magnets around. It's so much better than prying them up with your fingers.Thanks to Al Rorick.

Use these for, clamping, pickup magnetizing, hold tools and screws, keep solvent cups from spilling, get sticky Floyd Rose saddle blocks out. I honestly have used these in one way or another on every job I've done since getting them.

just love them

i really enjoy working with this magnets. They make gluing work on acoustics really easy.

Great magnets - just wish the handles were a tighter fit

By John David James from Old Bridge, NJ
(Customer's Reviews) Friday, July 15, 2011

These magnets are every bit as strong as everyone else says they are; be very careful with them - not only around sensitive electronics and pickups, but also around your fingers! These magnets will slam together if they come near each other and if your finger is in the way, well...

I wasn't crazy about the way the handles fit into them, though. No matter how much you screw them into the magnets, they don't quite fit "snug." It's possible that they were designed that way, I suppose. Otherwise, excellent magnets for use in repairs.
