Have to cut a lot of fins on cylinders. I added this Cross slide stop to control the depth of cut. The fin OD is 1.375, the bore is 1.000 The valley depth between fins is 1.125. This only leaves .062 between good cut and disaster. It mounts to the carriage via the two 6 mm holes for the Follow Rest. Very simple to fabricate.
