Re: speed control
I have one on my Shopsmith Mark V. It works well and provides enormous
torque sown low. But I've relubed it on occasion and I definitely wouldn't
call it "simple." The CONCEPT is simple, but changing

Re: Motor swaps?
The other part is a mini lathe has very little speed control
Some have 2 speed and others have 4 speed . The rest of speed control is done with the motor control.

Re: Motor swaps?

Re: Motor swaps?
The tread mill motors are a good motor for a larger lathe . I have one
on my South Bend 9" lathe & love it . For one of these 7" lathes I think

Re: Motor swaps?

Re: Motor swaps?
I think the reason we don¡¯t hear a lot about using different motors is that places like LMS sell stock motors. If you need to replace your motor the easiest way is to buy an exact replacement which

Yes, it should be clear that you can¡¯t mount the DRO at three locations and have them slide accurately unless you drill the mounting points with 0.0001 level precision. The ¡°roller¡± was to be

Re: Motor swaps?
This is simply curiosity, I don't currently have a 7" lathe, but I'm sort of a small lathe junky so it is just a matter of time.

I am seeing many old posts appearing when I open Unimat site.
Any ideas as to what is going on? Or am I missing something? I am seeing old posts as far back as 2010.
