Instead of the built-up traverse handle, I have made an extended mount from aluminium stock, with the rod running in a ball bearing at the outer end. The graduated handle is a proprietry item from Arc Euro Trade. It is graduated with 50 divisions, which fits nicely with the threaded rod which I have changed to 10mm diameter x 1mm pitch. Also shown is the angle indicator attached to the cam bar. I saw this on Bob Unitt's site and nicked the idea from there.
