I'm not usually one to make a piece of machinery, tools yes, but
this has some interest.
I've always had space limitations which is why the commercial units
have been my goal and the smaller commercial units are pretty quiet.
I assume that the hand built ones are quite a bit louder? Are they
more powerful? Can you load up a lot more media? What's the limit in
weight and in bowl size for the hand built units?
I recently saw that Gesswein is selling mag. tumblers that utilize
regular ceramic media (in modified bowls). It would seem to me that
the size of the media, stuffed into a small bowl like that wouldn't
be very efficient, but if it works it would be very useful. Do you
think a bowl could be made that could utilize standard ceramic media
in the hand built units, too? I assume that if you could, and if the
unit is generally more powerful than the small commercial units that
you'd probably be able to use a larger bowl. I'd love to see how the
bowl works in the commercial unit, but I've never seen it live.
