Yes...yes I do know.You certainly have to know of the old rock tumblers that came long before the vibratory cleaners and were adopted by reloaders to "tumble" their brass instead of rocks.
Which came first really has nothing to do with the definition of the word "tumble". If you look at the definition of the word, both mechanisms fit. One rolls, one vibrates, and either way the cases are tumbled through the media. I would submit that the word "tumble" has been around longer than either of the polishing mechanisms.I maintain that its use is actually a misnomer since the term "tumble" first came to use with the cannister type tumblers which did "tumble," and it does not accurately describe the action of the vibratory cleaners.
For that matter, if you look at the source of the word "tumble"
I'd say that favors the vibratory tumblers[Middle English tumblen, frequentative of tumben, to dance about, from Old English tumbian.]
