Clamps for woodworking and luthiery

Clamps are essential tools in luthiery, used to hold components in place during various gluing stages and, more generally, in woodworking. Typically, a clamp consists of a metal bar, two jaws (one fixed and one movable), and an adjustable pressure mechanism operated by a threaded rod.

Types of Clamps Used in Luthiery:

Body clamps: Specifically designed to close the instrument’s soundbox by gluing the plates to the ribs of instruments like the violin, viola, cello, and double bass. These clamps ensure even pressure along the edges, providing a precise and stable bond.

Lining clamps: Used to secure the linings during gluing, ensuring they adhere perfectly to the ribs of the instrument. They are available in different sizes to fit various string instruments.

Spring or Pinch clamps: Ideal for applying quick and even pressure on small surfaces. Their ease of use makes them perfect for precision work.

Lever clamps: Allow for quick and powerful tightening, useful for tasks that require higher pressure.

Tips for Using Clamps:

Surface protection: It is essential to use rubber, silicone, or cork padding on the clamp jaws to prevent damage to the delicate surfaces of the instruments. This precaution preserves the integrity of the wood and its finish.

Even pressure distribution: Ensure the pressure is evenly distributed to avoid deformations or damage. Using multiple clamps, strategically placed, can help achieve this goal.

Choosing the right clamp: Select the appropriate type and size of clamp based on the specific task to ensure more efficient and safe work. For example, when closing the body of a violin, it is advisable to use shaped clamps that follow the instrument's curves and have soft padding to avoid damaging the edges.
