    I know it’s probably on the site somewhere but the search feature isn’t that great. How do I remove metal oxidation? I have a manual ball loading rod from the 1960’s that I want to shine up. Simple polishing compounds don’t work.

    Probably need an abrasive first, then finer polish after. Have you tried a polishing wheel and the black (abrasive) rouge? I'd put this in a cordless drill running against the rotation of the polishing wheel and use a bunch of black rouge on the polishing wheel to grind off the oxidation.

    If that doesn't work, fine grit sandpaper by hand, then the wheel with black rouge, then red, then white.

    A dremel and a polishing wheel work great. You could also just buy another one. Marco usually has them.

    I like the big polishing wheels because it covers more area faster. The Dremel wheels are so small...

    Vibratory tumbler should take care of the oxidation but that won't do anything for the pitting. Walnut shell media does a good job with polishing compound but there are other media available.

    I would just buy a new one but I couldn’t find them anywhere. I can’t find them on Marco’s site. I know PBR doesn’t have the Gottlieb ones at least either. Although this is a Williams so I suppose I could check.

    Chuck it in a drill press (or hand drill) and spin it between progressively finer grit paper. Then polish the same way.

    Have u tried evaporust? Hft cheapest

    #9 4 years ago

    I found an old horseshoe on the farm, prob 80 to 100 yrs old, put in evaporust for 2 days, all rust pretty much gone. Still needed to be brushed hard, but was amazing what it takes off. Filtered it, and reusing

    48 hours in evaporust didn’t do much on the handle end. It did help on the shooter tip end. It polished up pretty decent which you can’t tell in the pictures. Wherever this machine was kept made the door skin and the shooter rod and ball lift rod rust heavily but oddly enough nothing else. Inside of the door and machine are fine. I think they painted the front of the machine to match the rust? The whole front is painted an even maroon/red color

    Pictures? All we have is the ugly "before" ones.

    I’m going to regrain them one more time. I need to pick up some finer grit paper. I think I used 220 because that’s what I had laying around. I’m only doing again because I’m picky about things. I’ll post some pictures when I get a chance.
