I am upgrading a EMCO 220P lathe and wanted to see how others are handling the operation and utilization of the Tail-stock.The lathe has a pneumatic tail-stock. The original control had a sensor for fully retracted and 2 sensors that where attached to a sliding block that somehow registered with piston location and was adjustable with thumb screw. Has anyone else converted one of these and how did they manage the tail-stock? I am thinking of not putting a sensor on the tail-stock and just using 2 outputs to control solenoids. 1 for extend and one for retract and then adjust the pressure regulator for amount of pressure exerted on the work piece. After all, the tail-stock is for live center support of work piece only and don't plan on using is much, but want it available (I Think). Thank You.

The logic for the sensors is pretty simple. One sensor checks that the tailstock extends when commanded, so the machine doesn't try to run without the stock engaged. The second checks for overtravel, in case of no part or short feed. This is how I understand it from the manual. I haven't gotten that far with other being retrofitted. These machines could run with bar feeders and sensing was there to prevent trouble.
