    I tore down the top side of my Harlem Globetrotters and threw all of the metal parts in the tumbler. Last night it had been running for about 48 hours and I took a look at the parts. The hardware is not shining up much if any at all but all of the other metal parts look great! I'm using walnut shell media and added some Flitz to it before I started the tumbling process.

    So, my question is, is there a plating on the hardware that is gone and no amount of polishing will make it shiny again or maybe am I using the wrong type of media?

    How long has the current media been in service? After a while it can lose it's potency.

    When you say hardware are you talking about the bolts and screws? If so, I always found I had to buff those on a wheel one at a time. Tumbler did not always get the heads of screws very well especially if they where really funky.

    i run walnut with novus2 for 3 days, then corn cob with metal polish for 1 day.

    I think I've only used it on one tumble job before this so 2 to 3 days max.

    Yes, the bolts and screws. They weren't real nasty going in just kind of dull. I never thought about buffing but currenlty don't have a bench grinder setup. Is it pretty quick, just a quick buff or do you have to work at them for a while?

    What do you use for a polishing compound?

    does this method make screw and bolt heads shine like new?

    These came out of walnut media with mothers mag wheel polish after 72 hours....

    I was getting mediocre results until I added the polish...also, you need to change the media when the particles start to loose their edge

    Wow! Everything except for my hardware (screws, bolts, nuts) looks close to that shiny. Is the mothers mag wheel polish that much better than Flitz I guess?

    it does a very good job for me, but does depend on the condition of the parts before. I have noticed the tumbler does a very good job if they are like oxidized or corroded or just very dirty BUT if they are extreamly rusty or lost there plating they really need to be replated

    This last batch of parts was just oxidized. I turned it off last night after 72 hours and about everything polished up great except for the hardware is still dull looking. I'm going to probably try a few on the buffing wheel to see what happens. Next time I run parts through the tumbler I'm going to have to try to add the mag polish. Is this what you guys are using and if so how much would I want to add for one of the large tumblers?

    I stick screws & bolts into my drill and spin on a cloth with Mother's Mag. Shines up in a few seconds and no walnut to pick out.

    I have started to polish exposed screws (ie ones in which the heads are clearly visible in the game - on ramps, tops of posts, etc) by hand with a metal polish. The tumbler works too - I used Novus 3 with walnut media, but I usually reserve that for real big jobs

    Damn that’s a good idea

    I use Never dull polishing wad, and get good results Sometimes you have to try a few compounds and some elbow grease lol

    #17 3 months ago

    Last night after work I picked up some Mothers Mag & Wheel Polish. The day before I bought a buffing wheel from Harbor Freight which I mounted on my bench grinder; it spit strings everywhere for about the first 45 minutes, but that's another story. Anyway, I lightly locked each piece of hardware in my vice grips, dipped the head in the Mothers polish, hit it on the buffing wheel for a few seconds while turning it and the results speak for themselves- before and after picture.

    I would like to try adding the Mothers to my tumbler for some other hardware and maybe some old balls I have sitting around. I have one of the large size tumblers. Does anyone know about how much polishing compound I would add to my media? Not sure if it would matter or not but my media has Flitz in it from the last 2 tumbling sessions.

    think ya forgot the photos if this method works well ill start polishing my screws rather then sticking in tumbler, advantage of tumbler is it does all the work

    #19 3 months ago

    SimiChrome Polish also works wonders on screws.

    #20 3 months ago

    I drill multiple holes in a piece of wood, screw the screws on the holes, and then run them all under the buffing wheel.

    It is easy, fast, and safe.

    I never use a tumbler.
    I examine and polish every part (even screws and washers) individually, and after that I ziploc bag every part by assembly number.
    For small metallic parts like washers, I usually use my dremmel tool with an appropriate shaped cloth or wool wheel and polishing compounds (usually brown and then blue or red).
    For small plastic parts I use such polishing micro-wheels (usually foam) with meguiars or novus polishers.
    Before I polish I run every part one or two times in the ultrasonic cleaner.
