Slow Speed Feed for the Mini Lathe...Use a DC Gear Motor 1 to 5 rpm Lead Screw feed

[Toolmaker51]

Thanks TM, great idea. I had thought about putting a 5 or 10 turn vernier dial on the speed control and then
calibrating it for threading rates. It will be a future experiment but I think it is worth doing.

Cheers, JR

If you mean feeding rates, that is perfectly logical.
Threading rates will never occur motor-controlled other than CNC. Every pass of threading deepens [torque load], mechanical or programmed transit of carriage is only way to insure intended pitch rate is maintained.
We have an import mill with a multi-turn vernier [RPM] speed control. Belt slip, low voltage, tool loading; stalling doesn't reflect in the LED readout. Adjusting X.X TPI or metric pitch would take all day, without breaks or lunch. And late for dinner.
