A thread from just last month about Shopsmith opinions.


The Mark VII seems similar in the capabilities of the individual functions. I think the main difference is the motor head now using Digital Variable Reluctance (DVR) motor and control mechanism.


I do not expect you have heard of DVR. It may have been introduced by Teknatool on their NOVA DVR lathes. I have the NOVA DVR 1624 lathe for 3 years. Works well. Quiet operation. Variable speed with a display for rpm, but not numeric display to set speeds, just and up and down button.

Teknatool site if you want to read more about the DVR motor.

The Shopsmith Mark VII motor is like my NOVA. The controller board is amp limited, so it generates 1 3/4 HP when connected to 120V and 2HP when connected to 240V. Internal autosensing of input voltage, so no voltage switch.
