Attractive solutions to tricky repair jobs! Make custom repair cauls, magnetize pickups, and more. 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. They also make great tool and part holders around the shop! This versatile 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. 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. 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.Our Guitar Repair Magnet Set is an attractive solution to tricky repair jobs: make custom repair cauls, magnetize pickups, and moreRepair shops are constantly finding inventive new ways to use these magnets - see how you can put them to work in your shopThis set includes 4 round nickel-plated magnets (two 1/2" (12.70mm) and two 1" (25.40mm)), and 2 magnet handlesWarning: These are seriously strong magnets, so keep out of reach of children - see Product Description for more information
