We design a unique jig for every model and frame size. The tubes and machined components are turned and milled as necessary and then mounted in the jig, fitting perfectly together. Then, these parts are tacked together by spot welding.
The frame is then welded in several passes by TIG (tungsten inert gas) to reduce distortion. By reducing the distortion as much as possible it improves the alignment of the frame. Our flat, even welds are time-consuming but ensure that the material is properly fused, improving strength.
