    Its a purpose-built unit, designed and constructed in-house (the 'main man' on the shop side is a co-owner and wizard who designed and built many of the daily-use machines). It has run for thousands of hours. The soap/rinse cycles are programed on an ordinary sprinkler timer! The Oil-Eater and water are fed and drained automatically, just load it and leave it. In that tumbler we use cylindrical ceramic media. The 304 bars, after forming are soft-soldered and silver-brazed per application.

    Oh, and its used on 304ss rounds from 1/8 - 9/16. A lot of them!

    After searching for something like this and finding nothing, I began to design one in my head.

    It would be fun to construct, but not practical in my current situation. I bet it gets lots of love in your shop.

    I'll ask the boss. Most of the machinery is proprietary and visitors are generally not allowed but he'll probably be ok with that tumbler. Might be a few days, I got a new shoulder last week, not all that limber yet.

    OK, boss says I can share whatever anyone wants to see about the long tumbler. I'll start with a couple of overview pics, then answer questions if there are any.

    But... the doc won't let me drive yet, I hope maybe in a week. If I haven't posted the pics here within 10 days or so and anyone is still interested, please remind me.

    I'm thinking that maybe you just need a different supplier for your SS?

    I kan't think of ever seeing greasy SS at all, let alone to the extent that you are talking!

    I have only seen it on 303 not 304 or ever on 316.

    I did just get set up with Swiss Steel yesterday and they are going to start supplying UGIMA for me. I havent been able to find a steady supplier for Improved Machinability stainless. in the sizes I run.

    The last batch for this job was from EMJ.

    The contamination doesn't look too bad at a glance, but if you handle a bunch of it you'll have filthy hands. It must be removed before soldering, brazing or tigging.

    Well I have no idea why 303 and not 304?
    They are both "18-8" and neither is going to rust anytime soon.

    ???

    Sorry it took so long. The OAL of this machine is just over 13'. the tumbler trough is made from steel pipe and is covered with commercial truck-bed coating. The stationary 6" PVC trough is a manual pre-wash, only used if we get a particularly dirty batch of rounds. The trough slopes down to the right where the drain is, the de-greaser and rinse piccolo tubes are leveled for even 'dribble'. The effluent dumps into the blue cascade settling tank. The machine is powered by a 3hp motor. The vibes cause a perfect movement of the stock through the media, resembling the rotary motion of a gatling gun barrel.

    Lacquer thinner would clean all the junk. A soak in a vat for a short period. You could reclaim the thinner if you let it sit for a little while.
    Last week the price was $22 at Home Depot. Price has jumped over $20 recently, wonder why... I know why.
