  • Ever seen a vibratory tumbler/polisher in OZ?

    Our American friends use vibratory tumblers (commonly used to clean and polish ammunition cases) to polish their ramps and pinballs.

    I found such a device for sale in Adelaide, but does anyone know where I can get one in Sydney or Brisbane?

    Thanks.

    I heard the Gun shop on George St [Sydney] down near Central sells them, at a pretty penny though. Im also interested in a tumbler at the right price....

      I've been there and done that. You've got a couple of choices:

      1. Order the Berrys tumbler from Pinrestore.com. Expect to pay around $US35 freight, for a landed cost of around $130 - $140.
      2. 17ackley sells them on Ebay. See here. Budget $15 for freight, so don't go over $125. He has them on all the time, and I've seen them go for $110 up to $170 - don't be afraid to skip an auction and wait for another. I waited for about 4 auctions before I got mine for $118. These tumblers are exactly the same as the Berrys ones. They even come with a Berrys compliance sheet. Berrys license them to Graf, 17ackley buys them from Graf.
      3. Make your own. A friend of mine did that and it's a superior tumbler to the Berrys. Made the bowl out of fibreglass etc. When I costed it (given I didn't have the various things on hand that he did), it turned out pretty close to buying a Berrys tumbler.

      Hope this helps.

        I have been looking for one to at the right price too. I was also told to try jewellry/gemstone people as they sometimes use them.
        Can you get the walnut shells and polishing compound locally?
        And is it possible to polish things like ramps etc I would of thought these would be too big?

          I understand that the rotational tumblers used for gemstones etc generally don't give as good a finish as the vibratory ones, although I don't have the practical experience to say. I use crushed walnut shells for media. You can get this from a decent size pet store (forget the ones in shopping centres - you're wasting your time with them as they're only good for selling cats and rabbits).

          A tumbler won't get ball trails out of metal ramps. You need to sand them out. I remove the mounting pins (that go through the playfield), then hit them with my proprietary upside-down-belt-sander-mounted-with-ubolts-on-the-bench tool. I then re-rivet the mounting pins back on, and we're ready to go. Mind you, for all this effort, it doesn't take long for the trails to come back but it makes the machine look spectacular in the mean time.

          For plastic ramps, flame polishing is the way to go, but my balls aren't big enough yet to try it

            Gemstone polishers work well. Leave the buggers running for ages.the longer they run.the better the polish.
            they are easy to make. i remember giving my dad a hand build one when i was a kid.im sure if you go googling you will find examples of diy polishers

              Thanks for the info Dialogpimp, i may look at option 2 for a tumbler.

              Wheres the best place to buy the media locally ? And which media is the best? Walnut ?

              Get into the flame polishing, the ramps come up like glass as im sure youve seen and they take alot more heat than you'd think. You dont need one of the huge **** off blowtorches like in TOP either i used the torch bit that game with my butane soldering iron. The results were AMAZING

                Just do a search on tumbler and you'll get a dozen or so options. I dropped in to their new store whilst I was up there and it's pretty big.

                    Im thinking more along the lines of dumping all the metal posts, screws, ramp guards etc into a tumbler during a restore i wonder how much fits in one load i usually replace the balls

                    Mark, What kind of tumbler and media do you use ?

                      I use crushed walnut media in mine with some Brasso and a squirt or three of Novus 2 in the mix. The media I use is Desert Blend Lizard Litter from a pet shop (Kellyville Pets, in Sydney). Some people use corncob media but I've not tried that myself.

                      Vibratory tumblers are excellent on metal posts, balls, screws, etc. Flat pieces tend to take longer.

                      Also, don't mix a bunch of posts and screws when you're polishing balls or flat sided parts as you'll create tiny "pits" in the ball surface from the other parts in the tumbler. Just do them separately.

                      As mentioned before, here's the one I made;

                        they sell them at Mick Smith's gun shop in sydney - near central - about $190 i think (when I investigated about 18 months ago)

                        remember if you buy from USA you will need a step down transformer unless it has a 240V setting - something with a mototr like that will have high wattage = expensive step down transformer.
