I have a 10-foot rail that was used as a fence on a radial arm saw. The original controller "Toolomatic" is not available. Could someone point me in the right direction for a controller and input device? It would be ideal if it could be set up to input measurements in inches. If it would need to replace the stepper motor, I don't believe it would be a problem. the current motor is approx 1/8 hp.
