Have Bridgeport cherrying head to trade for shaper head

'Cherry' sinking is an old method of die sinking, the cutter moves in a (usually) vertical orbital, but non rotating motion, and the tooling is lowered into the workpiece. The tooling is made so that it has teeth that cut in the direction of its movement, and can be the shape of the desired pocket minus kerf. Cherry sinking can produce square corners on some interior pocket walls, and make irregular shaped holes.

not quite , what it does is take a rotating cutter and move in an arc . So while traversing from left to right it will drop down and back up . Used in the days before cnc doing pattern work for castings and ornamental work unfortunately my camera is down
