So, I planned on surviving a while with the Dust Deputy, and my huge Genie shop vac for a while. I thought I would continue to make my little baby cyclone anyway and perhaps run them in series. This seemed like a reasonable idea, and eventually some day I would get a stand alone blower and build a full size Cyclone or Thien or whatever.

Knock-Knock… Who’s there… Opportunity….

So tomorrow morning I am going to speak with a man who wants to sell me:

1 – belt drive blower (with metal impeller rather than squirrel cage)
1 – 1hp. single ph. motor
1 – belt
5 – 4” slide gates new
5 – 4”clamps new
20’ – 4” flex hose new
4” PVC fittings never used
transition etc. Add to or build your own system.

So, he was looking to build up a system, but one of the ‘special kids’ that came to the shop, loved to sweep, and he could not bring himself to install the system (this is his story). Anyway, the shop is not going to be there anymore so all the parts other than the motor and blower are brand new. I just can’t see how I could pass this up for $50.

Tiny shop that I have, 12×16 I would think this should be sufficient or close to it. It is pretty much all setup for 4” but as I understand the Dust Deputy is somewhere close to 2”. Will I be able to use this with it somehow? Short of that, I guess I will build a Thien separator of some design because they seem quick and easy, compared to all the fiddly work I have been trying with the cyclone (still fooling with poster board and haven’t put snips to sheet metal yet. ) There is no bag or filter with this system, so the initial throught is simply to vent it outside until other arrangements can be made.

Is there any simpler design of a drop box that I could quickly incorporate?

Go to and get the idea of what a Thein separator is all about. Depending on what size impeller you have, a Thien separator will give you a big start on dust collection. One hp is not enough to run a distributed system, but should be fine one tool at a time. Venting outside is OK until you start venting warm air in the winter. One more site to check is They sell excellent cartridge filters.

I use mine on a 2hp HF dc on a planer, table saw, and mitersaw one at a time. My shop is small too so I need only 10 ft of hose. Works fine. Spend some time on that site. Lots of different adaptations, lots of info. For $50.00 you done good.

So, why do some people always start their sentences with so?

So, do they talk like that in real life?

I really want to know.

Oh no. Say it aint so.

It’s getting late, and I better go.

Sorry, I get a little goofy this time, 3 am, of morning.

‘So’, ‘Well’, ‘Y’know’, ‘Okay’ as well as ‘Ummm’ are vocalized pauses. They are poor form at best, and probably show their habitual use, which is not good for public speakers. I tend to use them, when posting, in absence of an individual recipient. It is a bad habit, and usually I am able to find the back space key before I hit send. But I was so happy about this deal that I simply hit send before doing the proper copy-editing.

Sorry if I have offended any wanna-be grammar faeries or spelling faeries, as that was not my intent. I will try harder next time. On the other hand, I believe I am in the midst of a poet.. Let’s see,”There was a woodworker named crank…” Just kidding, :)

Got it home, and laid out nicely. Here are some shots of it with descriptions

It is a big heavy beast. Looks like a nice starting point.

I was looking through the pieces and parts at Lowes and noticed the vent caps. I was wondering if they would work inverted as a baffle for a Thein separator. It would be conical, but pointing down. I would think it would force heavier things back into the cyclonic fray as it came up the angular slopes. Just a thought, haven’t figured out how to test the theory but it sounded good in my head.

I was thinking if I took an 8” one and attached it to the top of the lid pointing down, then put a 4” or even 6” pipe in the center of it, with the infeed anuthing lower than the rim of it … it might just work.


I still have my little DD on the way, it didn’t get here yet. But already I am planning on a decent sized cyclone or drop box or Thein separator. I assume I will be able to use the DD with my vacuum until I figure out how to plumb and run lines to/from this thing anyway.

Still open to suggestions.

New information… The label is not obliterated, but appears to be painted over. I scraped it off and find that this is

Kelco Corporation
Baltimore 24, Maryland
Ser No. 803 Size 10 Type 3

Does that mean anything to anyone?

I called Kelco in MD and from the serial they told me it is rated for up to 4500 rpm and would normally be run with a 2.5 HP motor. Furthermore the blades are shaped like they are to chop and pass materials. The impelled is a bronze aluminum alloy to prevent sparking. It was built in 1957 and originally sold to Chenoweth Rubber just down the street from them.

Other than the specs none of this matters except that it is interesting.
