I have been operating this lathe wired at 110 and it has been getting hard to start. I could help it by rotating the chuck to start it turning. The motor has a start capacitor and I replaced that with no improvement. The next step I replaced the motor, that didn’t do the trick. The control box has a transformer and two relays. I am wondering with this 110/220 option is the transformer part of the start up on the 110? It is a six wire configuration. Any thoughts? Thanks RD500

That’s not uncommon on older lathes. I’ve had one or
two I had to give a little help to in order to get the
spindle going.

A more powerful motor is one solution. Another
is to assess resistance in the headstock bearings.

Have you checked the belts for slippage? Also look at the pulleys to make sure they are not overly slick. If the belt is not slipping….Make sure the belt has not been handled with oil or other solvents/lubricants.

I can add more once I know the type of lathe and age.

I’d look into the motor more. Do you hear that little click as the motor winds down to shut off the start capacitor? It may be the internal switch is bad. Check out this link for troubleshooting with a meter.

Have your say...
