A Motor Upgrade, Screw Cutting & Power Feed

462 forum posts 113 photos | I documented my first attempt at swapping the single phase induction motor on my Taig lathe for a DC motor and Arduino control system last year. There was some interest and I have now reached the stage where V3 is working as designed if anyone is still interested!
Several people had cantilevered the Sherline motor and controller from the Taig headstock and as the motor I chose weighed about the same, that seemed a good approach. I had three other "ambitions" for the lathe. A decent mounting base, screwcutting capability and some form of power feed.
A geared 60rpm 12v DC motor in the lathe foot couples to the leadscrew by a dog clutch with a handwheeel for manual use on the other end. The pushrod is carried on two linear bearings mounted on the lathe foot. The carriage drive block and both coupling bars are locked onto the pushrod as needed with split cotters. The sample thread is held in an ER16 collet on the end of an arbour inserted into the spindle.
