Home made cyclone for MINI

[Wim]

Partly to save on bags and partly to see if I could make a cyclone, I collected some scrap multiply and started the designing process.
I mainly used 1/2" ply and made an octagonal bucket with a bottom that fits on the MINI and a lid for the hose connections. Below the lid are two 90 degree bends pointing in opposite directions.
I did a few tests and almost no sawdust ended up in the bag.

Pretty cool. So just a pair of 90s pointed in opposite directions inside? No actual "cyclone" shape funnel deal? Got a pic of that?

You might consider the just-received "Tools & Shops" issue of FWW (Winter. #223; p. 71) which includes a review of six vacuums including Fein and Festool CT26. Notwithstanding any of their conclusions or models selected, they have some thought provoking ideas on compact dust separation methods as key to any successful system.  [popcorn]

P.S. You might also see SCOTT W's apparently similar/duplicate effort below.

HANG ON -  [dead horse] I just noticed an ad in FWW from Oneida (Tools and Shops Issue, page 93) selling an Oneida D.I.Y. Dust Deputy as a retrofit for all vacs,  illustrated on top of a Festool vac, for $40.  [blink]  For that price, why bother with the effort to make an imitation?

Here is the lid of the contraption.

After some routing, planing and sawing I collected a 1/4 container full of sawdust and the bag has collected less than a teaspoon of wooddust. The mount of sawdust in the container showed a ridge on top in a circular form and the sawdust was only in one corner of the container so for me it proof that there is a cyclone-like air-movement in the container. For me it works perfectly and I'm very satisfied with the results.

very interesting , indeed. That idea certainly opens up additional building options.

I'm thinking of building one.  How tall did you build yours would you go higher or lower if you where to do it again?

 

[Wim]

I made mine 40 cm high, almost 16". Material is 1/2" plywood. The PVC pipe en 90 degree bends are 1 1/2" and I glued reducers in the top bend to enable the insertion of the rubber part that normally goes into the tool. The baseplate has the same width en depth as a systainer. The teeth for the clips are not difficult to make. As long as the clips will go over the teeth, you are good. The clamping force is from grooves in the sides of the pockets on the systainer. You can make the container a little bigger when you put the sides against the edge of the base plate.
I don't think I would change the height because it is working as is. Going lower could make it less effective.
If you like I could send you more pictures with details.

Perhaps we are not looking at the same thing, but it appears the Dust Deputy on top of the Festool vac is $289.95.  Are we looking at different items or am I not finding the $40 top-of-Festool variant?  Please see this website:

The $40 Dust Deputy is the basic model. It is just the cyclone unit by itself. No hoses, no buckets. It's intended to connect to your own containers.

The Ultimate Dust Deputy is the full boat setup, with a 9 gallon container and all the connections needed to put it on top of a CT. Oneida Air's web site says it's on sale for $199. (Regular price is $299.)
