Go-bar clamps in use. Click image for other photo.
The Go-bar deck, or the use of bent sticks between two solid surfaces, is a very old method of applying clamping pressure while gluing two parts together. It's absolutely ancient. In some early shops bent poles were used to apply pressure from the ceiling down onto a bench top. This method has always been used to clamp and glue bars on to the large, flat harpsichord, and later piano, soundboards. In recent times this use of props or Go-bars has been expanded and refined with the use of a variety of clamping boxes and sticks. When many bars are used at once to clamp all along a long brace or several braces at once it is important that the Go- bars apply even and consistent pressure.
We offer here Go-bars made of fiberglass rod. This makes each bar, or prop, absolutely consistent in clamping pressure, bar to bar and in use over time. These Go-bar rods are 24" long by 3/16" in diameter, with rubber tips on each end. You can either design your own clamping deck with this length in mind or cut them shorter to fit your current bracing box. 20 to 24 bars are needed to entirely clamp all braces onto a top or back at one time.
