Go-bar clamping is a popular technique for gluing guitar braces, soundboards and lots more. This is a fast way to hold all sorts of shapes that otherwise are really tricky to glue.
Strong flexible "go-bars" are placed under tension between the top of the go-bar deck and the wood being clamped. Setup is simpler and much faster than using standard clamps, and clamping pressure is more uniform.
We offer components, sets and instructions to easily build your own go-bar system, including radiused concave dishes for maintaining accurate guitar soundboard and back curvature.

"Gluing braces on tops and backs used to be a slow process. One session used to take me two hours, but with go-bars it's less than twenty minutes. I build a dozen or more acoustic guitars a year in my home shop. I couldn't build that many in my limited spare time without using go-bars."
— Todd Sams, StewMac production manager
