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 a tread mill motor could be a bit much & could cause

Re: Motor swaps?
I've never been interested in changing to a treadmill motor and controller because, from everything I've seen, when you slow a motor down electronically it lowers the rpm and lowers the torque. When

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

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. The Consew and treadmill motors seem quite popular. I just haven't

Re: Lipstick on a pig?
I have the iGaging dros on my Clausing 8520. One thing I learned in installing them is that only one end needs to be fixed, the other end can float. I installed a long DRO with both ends fixed and

Re: Motor swaps?
I have had the Consew 3/4 hp Brushless DC motor on my Craftsman 12 x 36 lathe, my Clausing 8520 Vertical mill and my 16 " Delta Bandsaw. I would think the consew motor might be a bit much for a mini

Motor swaps?
It seems like the motor / speed control is a common issue with the 7" and 8" mini lathes, but I don't see many motor / speed control projects discussed. I follow several different small lathe forums
