Problem with Axminster Woodturning Lathe

I have just been given a 20 year old APTC M950 lathe. All seems to be in good order and the lathe turns manually without any issues and the belt looks almost new.

However, when I press the starter button the lathe momentarily begins to turn but then almost immediately my fuse box trips (my workshop runs a high powered welder without issue so I don't think it draws too much power).

Anyone got any ideas where I start to fix this ?

Thanks for any help.

Unplug and then have a look in the switch box and see if there is a build-up of dust in there, even though it may seem sealed worth doing and cleaning out use a vac if you can. Check any wiring for damage.

If the above fails then go with my comment below.

I think that the electrics need looking at by a qualified electrician

Many thanks Derek. I'll try that and see what happens.

I have the M950, now 21 years old, and I had exactly that problem with it, I took the head stock back to the suppliers and they replaced to head stock after it blew their fuse as well. Derek's idea is probably the best place to start, if you can manage the basic electricity skills, the why not buy a new switch? You should get the details from the old one and there are plenty on the various auction sites.

The switch box is super clean and all the connections look solid. I need to dig out my multimeter and check whether there is any issues with the switches though. There is a centrifugal switch but it looks OK with no marks or charring on it. The motor itself looks really dirty though with a lot of wood dust inside the casing, I haven't tried to take it apart yet but will try to vacuum it out as best I can, as I'm not sure how easy it will be to take the whole thing to pieces.

Don't really want to spend money on an electrician until I've tried everything I can.

This sounds to me that it is the starter capacitor which is probably not working. this is a tubular unit usually bolted to the outside of the motor. You might also try spinning the job in your lathe by hand & then press your starter while it is rotating. If the motor then runs it is definitely the capacitor.
