Topic tags/keywords: cyclone

I am wanting to upgrade from a baffle type separator to a cyclone for my 2hp Grizzly dc. The problem is that sheet metal and I don’t play well together as I only have access to a stickwelder. So my thinking was that I would use forms and fiberglass mat cloth to make a cyclone (based on Bill Pentz measurements). What I was wondering though is if there would be a specific reason that I should or shouldn’t? I have done some searching and cant find where this has been done so has anybody done one or seen one? I would love to hear Your thoughts.

First off do a search on ebay for cyclone separator. I bought one on there about 5 years ago for $150 and it works fantastic. The same guy is still selling them there. Well worth the money and your 2 HP DC will work just fine with it.
I just upgraded from a 2 HP HF to a 3 HP Grizzly on my system.

Look at the Clear Vue Brand collector. They get by with a poly separator. Buying a separator would be a lot simpler and you should get a proven design.

Well, I forgot to mention that my budget is going to be well below either of those options thinking sub $50.

TJ, you may find that modifying that setup could prove to not be an upgrade. But to your question: fiberglass would probably be a great material for such a thing. You would sure need to get the inards nice and smooth as to not impede the vortex. My only real question to you would be, is there something unsatisfactory about your system that motivates you to do that much work to do the modification ? If its only about tricking it out a little to drop out the big stuff, why not go with a 30 gal. trash can and the seperator lid that just drops right on. They work quite well. JB

I am using a Thien type separator now but I have to empty my can when it is only about half full to keep from passing way too much through to the bag and filter and that is kind of a pain. This idea was brought on after I cleaned my dc filter recently, not a pretty picture. ps. the dc runs about 3-5hrs a day 5 days a week.

I suppose you could e-mail Bill and ask him. How about building one out of metal and solder it? Wood magazine had a plan quite some years back that only used pop rivets to hold the sheet metal, something like that might be another option. I built the Wood design, it was actually fairly easy, but didn’t have the shaped inlet or air ramp that Bill’s design has.
