Gene, I've been considering cnc-ing my little 7 x 12 for a while now but other things have had to take priority. However, I can't see why you wouldn't just want to hang a little Nema 17 motor direct onto the back of the cross slide screw. One of the 60 oz/in motors advertised on Ebay for about

Gene, I CNC'd one of the red Harbor Freight 7x10's by puttting a gearmotor with encoder (servo) on the lead screw and another on the x axis by mounting it on the BACK of the saddle with a sliding coupling made by drilling a cross hole in the end of the cross slide lead screw and another in the

You all know by now that I have one of those toy 7x12 lathes, this one with a Speedway decal on it. In looking for a place to put the crossfeed motor, it occurs to me the best place is probably on an extension bar (I have a good sized sheet of 1/4" alu) that places the motor facing away from th
