Abstract: A c-shaped clamp tool system preferably includes slider arms, one or more slider arm supports, pads, one or more threaded rods, and turning knobs. The clamping system preferably includes multiple slider arms and slider arm supports of different lengths. In a preferred embodiment, the slider arms are made of unidirectional pultruded carbon fiber and the slider arm support is made of woven carbon fiber.

Abstract: The carbon fiber c-shaped clamp tool is preferably used in wood working and instrument manufacturing. The carbon fiber c-clamp tool preferably includes a main body, carbon fiber sleeves, pads, one or more threaded rods, and turning knobs. In a preferred embodiment, the main body and sleeves are made of unidirectional carbon fiber. A method connects the main body and sleeves by extending the carbon fibers from the main body to the sleeves and wrapping them around threaded inserts.

Abstract: A tool for setting an instrument sound post preferably includes a bent tube, one or more string or polymer lines, a cradle end that grasps the sound post, and an internal locking mechanism to hold the sound post against the tool. In one embodiment, a single line is used and a closed loop at the cradle end of the sound post setting tool holds the sound post in place. In this embodiment, a double-chamfer threaded tube construction is preferably used to facilitate line threading. In another embodiment, the cradle end includes a loop and a ball to grasp the sound post. In yet another embodiment, the cradle end includes two balls to grasp the sound post. The tool provides an improved way to install a sound post inside a stringed instrument.
