I just installed a 1 1/2 hp - cyclonic vac system...

using this piping to run to each machine that makes "dust" or grinds.... using waste gates to maximize vacuum to each tool being used. (I have a couple Burr King grinders)

I built a table a couple years back that I'm now going to make a sheet metal collection area at the base - ala a downdraft table - and plumb a 6" straight to it in an effort to give me a place to grind or buff etc small parts.
Then I got a "big mouth" that I am going to put on flexible tubing -- and move that around to try to contain dust and contaminants as much as possible. And I'm thinking I should order another one and put it behind the buffer to catch all that debris.
