You really need to check if that holder is bent or loose. That commutator shouldn’t be the that black. Or any sort of black really, it needs cleaning. Doing both isn’t too hard. You need to

That is a commutator in desperate need of help. george

Here is a video viewing the commutator and brush holder. I used a Andonstar Microscope to get the video. ( https://andonstar.com/product/andonstar-ad203-handheld-portable-microscope/ )

" *Remove the belt so spins freely*." That leads to my next question. How to remove the belt? I guess everything that is removable from the end of the lathe must

Thd biggest thing is on brushes and comutator is they are clean. Now it gets harder to find. Check to see if electric at motor wire is DC. On some motors I would take wire come out motor and use DC

Progress!! I turned the lathe around, I was surprised how heavy the lathe is. I removed the shield, and the motor cover. I also removed the control panel from the front so that I could inspect

I have found the bug problem with magnetic starters. They are pain but to find and get too. Dave

Please post the wats you your mini lathe for your wife. I updated the rules and scorecard in files

I hope check all of that before posting here. But still a good question. I use to think on troubleshooting? to check the plug was not need. Later I found from tech happens all time. Dave

A easy way to eliminate the gear train is to place the high/low gear lever in a vertical (neutral) position and see if the motor works O.K. You could also try turning the chuck by hand in both the hi
