Question(1) Please tell me types of adjusted speeds. Question(2) Can the machine rotate in reverse ? Question(2) Power supply is 110V ?

Speeds are adjusted by changing the drive belt on the pulleys from 635RPM, 805RPM, and 1100RPM. We can custom pulley these to run 1175RPM as well for expanding drums. 

The lathe can go in reverse only if you switch the motor wiring. It is standard in a single direction.

Standard power supply is 110V/60Hz.
