End view of the slot we are cutting in the brake shoe ring with the custom tool. Several times the cutter dug in and stalled the lathe, causing the belt to slip off. The slipping belt is actually becomes a safety feature, saving the lathe and motor from damage that might occur with a direct-drive system. But it is still quite alarming when it happens. Even with everything a tight as we can get it, the tool, lantern style toolpost, cross-slide and compound all are flexing a bit, giving us trouble. Also when the cutter digs in the part spins or shifts on the chuck, insuring this operation will not be highly accurate, but probably just acceptable.
