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″ (30.16mm) 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.
