mini cyclone

Yes I used it to vac the floor and made a bunch of cuts on the bt3100. It works very good. im sure improvements are going to happened soon!! Thats what I like to do...lol

My Shop-Vac Cyclone is still in service, although the drum is on it's last legs. I agree that a center location for the outlet (i.e., to the Shop-Vac) would be more effective.Some things I have learned:

Don't suck up handplane shavings. . . they muck up the cyclone action.

When the drum (or, in your case, the tube) gets to about 1/2-full, chips and dust make their way into the Shop-Vac. I put some coarse window screen over the outlet (i.e., to the Shop-Vac) and that helps. It does, however, reduce air flow a bit.

I use drywall bags in the Shop-Vac cannister; that helps keep fine dust contained.

Good job!

Thanks I'll give that a try. I downloaded the excel sheet to make Bill's cyclone. I think im going to make one of the to put ontop of the tube.

So many projects, so little time...lol[B)]

Regarding the loss of air pressure: cyclone separator will reduce air pressure somewhat compared to a shopvac without separator when shopvac is completely empty. However, as the shopvac gets full and clogged, the air pressure in a shopvac will drop. Separator prevents shopvac from getting clogged and allows you to have decent air pressure longer. Unless you empty your shopvac religiously often - separator will benefit the air pressure.

Is there a reason to use the concrete tube?? Would this work with either a round plastic or metal trash can using the lid as the...lid?? Just trying to capitalize on the cheap and easy method of dust collection.

Thanks

A plastic or metal trash can isn't strong enough to stand up to the vacuum. They're designed to be strong against outward pressure, but not inward. If you provide the slightest resistance to the intake it'll start to collapse. DAMHIKT
