A dedicated puzzle piece notching machine.  Using Qbasic the PC controls two stepper motors, 3 air cylinders and two solid state relays. A small stepper does piece positioning, a large stepper controls the cutter height.  Two air cylinders are for piece clamping and one for table movement. The two solid state relays are for the saw and dust collector AC power. Started out as a Delta table saw.  The only original parts left are motor, table and power switch.  Designed  and built by Jerry McFarland
