Comments on: Cyclone Dust Separator for Shop Vac http://www.atterberry.net Having nothing to say has never stopped me before...

Most folks don't understand the physics well enough to get that critical detail right. :-) Yes, intake for the outlet [ie, line to vac] should be anywhere from 1/4 to 1/3 of the way from the top of the cyclone, and shouldn’t be more than 1/3 the dia. of the cyclone at it’s mouth [eg, a 2" dia line to vac inside the cyclone should not extend below a pt. where the ID of the cone is <6".] Kudos on making it clear that the intake line at the top of the cyclone must be tangential!

I don't really know if that's the optimal setup, but it makes sense (not providing a straight path to the vacuum). The only update I have, having used this setup quite a bit, is that the mighty putty is cracking and not holding up very well. I've since braced the inlet tube using a piece of wood run from the top of the cone to the bottom. I resealed that joint with regular silicone caulk. Best of luck!

This way it don't go right into the shop vac. Excellent setup, I love it, you got me building one. I appreciate any feedback, before I throw away to much money.
