  • Cleaning/restoring a chuck

    I recently picked up a six-jaw bezel chuck for a watchmakers lathe. It has some surface corrosion/discoloration. I am going to clean it up and lubricate it, and was thinking of polishing off some of this discoloration. I haven't checked the runout yet, and I don't want to make it any worse than it is, of course.

    Obviously I will need to use something mild as to not affect it dimensionally. I use a product called Simichrome by Happich for general polishing around the workshop, I am thinking it is mild enough to polish without damage.
    I read through another thread on this forum about polishing machines, a product called Knorrostol was mentioned, I imagine it is quite similar to Simichrome. There was also mention of a hydrochloric acid wash and polish, and recommendations to leave it alone since it doesn't help and could possibly hurt.
    Any other thoughts, or does the same apply to this chuck?

    Thanks,
    Phil

    try pickling it in a vinegar and water solution over night and then use a buffing wheel with jewelers rouge...........
    But that's just me.

      I think I would resist the urge to make it shiny. Just clean and lube, and let it go at that.
