Note that the headstock, DC motor and speed control can also be ordered with an ER-16 collet spindle nose in place of the standard Sherline #1 Morse internal taper and 3/4-16 thread on the nose for those who prefer to use ER-16 collets. Sherline does not supply the collets or the nut, but they are available through MSC and other tool suppliers. Keep in mind that if the ER-16 nose is ordered, no Sherline accessories that use a #1 Morse taper or 3/4-16 thread will work on this spindle.

To power, and control the motor a more sophisticated speed control unit is required. This unit accepts any incoming AC current from 100 VAC to 240 VAC, 50 or 60 Hz and automatically outputs 90 VDC to the motor, so this unit can be used anywhere in the world without a transformer. All you need is the correct wall plug or converter. Once the on/off switch is switched to the “ON” position, a speed control knob is used to vary the speed over the entire range. With the pulley in the “normal” position, the speed range is about 70 to 2800 RPM. In the “high torque” position the maximum speed is cut in half but torque at any given speed is much greater.

This unit can be purchased to replace an existing AC/DC motor on an older Sherline machine, to turn a mill XYZ base into a complete mill so that you don’t have to swap power units back and forth from the lathe, or as a stand-alone unit for custom tooling designs. This very compact and well-engineered unit costs far less than other DC units of similar power offered in major industrial tool supply catalogs.
