    Default Noisy lathe at startup.

    Hi all, my recently acquired Sheraton Conquest 10 sounds like it isn't happy on startup. I've attached a brrief vid. sometimes it goesd on for longer, but of course, everytime I went to record, it only groaned briefly.
    Any thoughts would be appreciated. (Starter condensor?)
    Is it something I need to fix in a hurry?
    Thanks

    Hi Vic,

    Have you checked the gearbox oil recently ? It sounds like dry gears until they get splashed with lube.
    Best Regards:

    Thanks. The headstock reservoir oil has been changed and is at the proper level.
    As far as I know the quick change gearbox gears get lubricated but don't have a reservoir.
    In person, the sound seems to come from the rear, around the motor area.

    Single or three phase.

    If its single it could be a loose centrifugal switch?

    If its single I would be checking that out before running it again. If it comes off that can make a real mess,

    Default Update

    I had an electrical guy have a look and he cleaned it up and found part of the inside casing rubbing against the rotor. Sorted that and it runs smooth as silk now!
