Perform repair jobs where your arm can't reach.
Magnets make tricky interior alignment easy!
Scissor Jack
Many hours — and a pile of prototypes — went into the development of our Scissor Jack. There's no other tool to match its versatility and ease of use for interior acoustic guitar repair work:
• Holding braces, repair cleats and bridge plates for gluing
• Aligning the sides of a crack for gluing
• Supporting a fretboard over a guitar body for installing frets
• Simulating string tension on an unstrung guitar top, for accurate bridge saddle work and neck resetting
The Scissor Jack has smooth thumbscrew height adjustment. Best of all, it's easy to add the flexible extension cable supplied with the jack, so you can operate it deep inside the guitar where your arm can't reach!
Finally, one more cool feature: it comes with magnets. They help you position the jack and align exterior cauls in lots of versatile ways that make tricky clamping a LOT easier.

The Scissor Jack has sturdy machined aluminum, brass and steel parts for durability and long life in the busy repair shop. The glue-resistant polyethylene cauls are specially recessed for the supplied magnets (the jack can be used with or without the magnets).

Tips for using the Scissor Jack:
|
Use cauls to help spread the clamping pressure. Here the jack is applying pressure to a soundboard X-brace, while sitting on a caul that spans two back braces.
|
|
Here we're using exterior cauls on both sides of the guitar, to give the jack something to push against safely.
|
Magnets make caul alignment easy. A few examples:
|
With a steel washer (or magnet) outside the guitar, the jack hangs upside down, ready to hold a crack repair caul in place.
|
|
Notice the exterior cauls.
|
The gluing rig was easy to make; simply a 1/2" repair magnet screwed to a wooden dowel.
|
|
Here's a curved wooden caul that matches the curve of the guitar side. It has a magnet attached that holds the jack.
|
Warning: Seriously strong magnets!
The magnets supplied with our Scissor Jack are made of rare-earth neodymium boride. They can magnetize, degauss, or re-polarize any ferrous or magnetic material, including electric guitar pickups. Keep them away from magnetic storage media such as floppy discs, cassette and video tapes, as well as pacemakers, computers, CRTs, TVs and watches. Keep these magnets out of the reach of children! If more than one magnet is swallowed, they can attach to each other and cause intestinal perforation or blockage, which can be fatal.
