Re: Motor swaps?
I have a couple of the Consew motors, I have "thought" about putting one on my mini lathe. But I have so much to do that I probably will not get around to doing it. The Consew gives full torque at

Re: Lipstick on a pig?
One of the nice things about iGaging DROs , at least the ones I have, is you can cut them to any length required, they do not have to hang over the end unless you need the length to measure travel. My

Re: speed control
I have an 11" Logan with a Reeves drive. It is an effective mechanical solution. I can see why electrical solutions have replaced them. It is quite noisy for one, it also takes up a fair bit of space.

They're rough on their belts; before solid state drives became affordable, they were about the only reasonable way to make a variable speed drive. With modern electronics they're no longer a good

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

Or free, often with convenient mounting holes included. Computer hard drives offer some really nice ones; older server-grade ones can have phenomenally strong ones. Be very careful to not let them

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. I am using 1 hp and 1000 rpm just

Re: Motor swaps?
I agree Working with light lathe you different techniques over a larger lathe. On large I run the slower and take a massive cut. The mini lathe I can run at higher speed and take light cuts. The down

Re: Motor swaps?
This depends entirely on how your controller works. Back in the old days, we controlled motor speed by controlling the voltage we send to the motor. There are still many controllers that work that

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

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
