Reading and hearing all the cautions about breathing grinding dust, I set up a mini-grinding station. There's an 8" coarse and fine grinder, a 6" set up with a 3M deburring wheel and a silicon carbide wheel, and a recent addition, a Deckel clone cutter grinder. There's a pretty good learning curve on that machine, and a million mistakes one could make, but wow, what precision!
So I have basically mocked up a vacuum system plumbed for convenience, with cut-off stubs for flow control. The vacuum motor will be on the other side of the wall for sound reduction. I think the precision work with the cutter grinder is incompatible with roaring vacuum noises. I used some 2' square aluminum tiubing, rough miters at the corners and currently held together with electrical tape. There are sheet metal clips that slip over the tubing and block unused ports, and also for fun and evaluation a rotating flap with external control and indicator. I machined a block of Delrin for the main vacuum port, waiting only for a choice of vacuums and hoses.
I don't expect the Nobel Prize in Vacuum Technology, but if it picks up a fairly high percentage of the grind, I'll be happy.
