StewMac Scissor Jack

Perform repairs where your arm can't reach. Our versatile Scissor Jack lets you perform tricky repairs inside an acoustic guitar with ease. Many hours, a pile of prototypes, and inspiration from luthier Freddie Cisneros, went into the development of our Scissor Jack.

The perfect tool for:

• 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 comes with:

• Thumbscrew height adjustment
• Flexible extension cable
• Glue-resistant polyethylene cauls (specially recessed for the supplied magnets)
• 2 rare-earth magnets

Magnets make tricky interior alignment easy! They help you position the jack and align exterior cauls in lots of versatile ways that make tricky clamping a LOT easier.

Made of sturdy machined aluminum, brass and steel parts for durability and long life in the busy repair shop.

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.
