GAMMILL ** BEVELED WHEEL (3111) part #8-3116
Particularly of value on Statler systems using the original track, the Beveled Wheel allows the machine to be much more accurate in pattern placement. Any side-to-side movement of the machine on the cross-track creates inaccuracies in stitching, and worn original U shaped wheels definitely need to be replaced with this wheel.
In the comparative picture below the main image these are the type on the right, having a more ‘v’ shaped groove. Clicking on it will enlarge for better comparison.
