Lathe - Power Supply Q?

[EngineeringTatty]

Had the lathe running on the bench today, it has a one of these on/off switches with the big red stop knerb....Sorry dont know its correct name.


It ran fine when I bought it, now the power to turn the chuck over is intermittent, motor gets warm/hot to the touch. IE it runs , glitches, slow runs,glitches, hics , runs a bit etc. Sometimes doesnt fire up at all. When I whipped the switch cover off and worked the switch manually it generally worked.


I ran the motor off the lathe with a plug on, and it threw my garage trip. However it ran smoothly and quietly prior to clicking the trip. So rather than go for a dodgy on/off switch I have stripped and cleaned the motor. Brushless type, and all appeared well other than being grubby.


Ive just noticed the lathe headstock bearings were dry (now oiled) , could it be a "tight" lathe causing the hot motor and the trip dropping out ? It was reasonably tight to turn over by hand...?

Bearings need greasing not oiling.

Did you check for correct belt tightness if its belt driven?
What make of Lathe by the way?

Some headstocks need oiling, some greasing.

Its an Ideal Machine Tool Co lathe as ID by GeorgiePorgie recently.


Pinch bearings with a neat little oil cap ontop, so no nipples....


Belt seemed fine, was actually tight to spin over by hand prior to the motor coming off, I put this down to not knowing the machine. But noticed the tightness once the motor was off, where I wouldnt expect a lot of resistance.

must be losing me marbles?

Take the belt of,does the chuck spin easily? has the machine got a clutch? something might be binding?

No clutch - It spins over now Ive eased the pinch bolts x2 and dribbled some oil onto the bearings.

Prior to that it was tight to hand spin.

Dear Lord don't let Brightspark see that wiring

Poor old stud gear looks a little sorry for itself - or is it the camera angle?

The whole thing needs a good clean up, the gear teeth are fine its the picture.

Its had years of oil krud build up, and no cleaning.


Wiring - Also falls within the tidy it up jobs. Not about to go anal with the wiring, no chafing, no exposed wires, covers off to clean it. But it will get a tidy up and some insulation added.
