The OP video is not mine, I don't speak German, Stefan Gotteswinter does!
I bought these:

Mine tumbler is cheaper and the movement is a little different. There is that circulation that turns media/parts up to bottom, but the media also "walks" inside the tumbler in clockwise direction. I noticed that polishing works better when media density is close to part density. I am not sure if this is a general thing or just experience. Also the "cutting oil" seems to help and prevent post polishing rust, but it is hard to put number on it.

Pekka,
Thanks for the info. It sounds like your media motion is similar to mine. Mine has a bowl with vertical ribs in it, which must hinder the rotating media. If I can get a Leyman bowl of similar size I would be interested to see if there was a difference.
Sorry about the mix up with whose video it was.
This morning I added some detergent and water in the same quantities as in Stefan's video and although it has not been running that long yet it does seem to be working better. That is with the plastic/abrasive media of the same shape and size as in the video.
Mine has a 2 pole motor in it so it spins at just under 3000 rpm @ 50 Hz, although made for the US 60 Hz which would be 3600 rpm. I expect that with a 4 pole motor and half the rpm the magnitude of the drum motion would be greater but whether that would clean/deburr/polish any better is anyone's guess.

Not sure if this is any help
The uk aquarium gravel is most lilky pea shingle that helps keep the white hard water line around the top of your aquarium tank also helps to kill your plants by rasing the water hardness and ph not so good for all the fish
However some peple use german quartz gravel as its inert

Here is a link to a 20 second video of mine working (or not working) with two different media loads.

Compare to the first 10 seconds of Stefan's video. It is not hard to see why mine is a disappointment.
PekkaNF:
Mine is something in between. I noticed that total weight of the "load" is a factor. My brother has a Lyman case tumbler, that circulates mead a little faster with brass cases and corn cob or walnut. I don't know how much these are optimized (or marginal design). Mine is that loud that I put always lid and leave it running on garage floor (no way of running of the table or scuffing something).
