Hmmmm! I may have to look into that. Your comment, "All that fine dust is ejected before settling on my machine equipment" makes me think, "if I built one of those and also used it when using my angle grinders and disk grinder I might keep my shop a lot cleaner." I'm thinking a unit that I could roll to where I do each operation.
Thank you, of course, now my forehead is flat again from slapping myself and saying, "now, why didn't I think of that.:les:
