I just bought a used carba-tec mark II mini lathe so that I could turn a few things every now and then. The only problem is that it turns in the wrong direction. I know I am not crazy, and I could not find a reverse switch. I am not familiar with these lathes. I was able to turn a rattle for my daughter, but I had to do it on the back side of the lathe. Did the previous owner somehow reverse the direction? Any help would be appreciated.

From looking at the manual, it appears that is using a variable speed DC motor and does not have a reverse. Easy fix though would be to just swap the two wires going to the motor.

I know this has nothing to do with a lathe, but it does fit the question or problem that Matt is having.

I have a MK tile saw that the switch went bad. When I removed it, one of the wires came off the capacitor. After taking the switch apart and defusing the contacts, I put it back together and looked at the capacitor to look for the connector that the one lead came off of. I then connected the wire, and put the cover back on. Well, of course, “off” was now “on” wouldn’tcha know. I figured just get the job done, and fix it later. It did work properly, except the off and on being opposite from before. A week later I had to make about 2 more cuts, and the blade was now rotating in reverse.

As the motor is a Baldor, I called a local Baldor service center and was promptly told that “does not, won’t, and can’t happen”. Got nowhere fast with those guys, so I took the switch/capacitor cover off, and looked even closer at the connectors on the capacitor. I put the lead on another one. I turned the switch on, and the motor rotated in the proper direction.

I have no idea how it went from forward rotation to reverse after that week I used it. I will never know why as if a motor is designed to rotate one way only, it can’t happen. Baldor service said so….. Jerry (in Tucson)

I switched the wires, and it turns the correct direction now! Thank you! Yeah, I don’t know why switching the wires will switch the direction, I guess because its a DC motor

That is all a reversal switch does anyway.

Try running it with the motor on the right side, instead of the left.

that happened to me one but not a lathe, one of those cheap battery operated hand fans. the fan was turning in the wrong direction and blowing air out. I could figure out how to fix it so i put it back together and it worked. I think I put the 2 AA batteries in back wards, that must have changed the polarity
