The Longworth self-centring faceplate is made from aluminium with a threaded connector allowing quick assembly. It has the advantage over standard Cole jaws that you do not have to adjust a number of threaded screws.
The faceplate can be screwed directly onto the spindle
Only the quick release mechanism of the holding pins is activated to clamp the bowls.
The holding pins can all be moved together to enlarge or reduce.
