Quick-Return Slotted Rocker Lever
A 159 mm Whitworth-style quick-return rocker lever. One end has a 22.05 mm press-fit pocket for a 608 bearing as the pivot. The 13.4 mm wide, 80 mm long through-slot is sized for a 624 bearing (13 mm OD) on the crank pin to roll in. An M4 clearance eye at the far end connects to the output link. It turns a motor crank into a slow working stroke and a fast return stroke for shapers, wipers, kinetic sculptures and automata.
