Folks -
I am the new owner a Clearvue Mini CV 06 (similar in overall design to an Oneida Dust Deputy). It is paired with a brand new Ridgid 11 amp shop vacuum. Mods to the vacuum include:
1) drain outlet cap threads sealed with plumber's tape;
2) weather stripping added to top of shop vac bin for a better seal (substantial improvement in suction);
3) Ridgid diffuser/muffler added, stuffed with stel wool.
4) HEPA filter.
The run from the cyclone to the vacuum inlet is extremely short, less than a foot. The vacuum pulls like a freight train.
My problem is that the suction is so great the container beneath the cyclone collapses. My first container attempt was a Rubbermaid Brute 20 gallon trash container. The top is fabricated from 3/4" cabinet grade birch plywood, router grooved and weather stripped on the underside for a tight seal to the trash can. The cyclone is attached to the top with carriage bolts, and sealed with silicone caulk.
Even at steady state, no load running, the trash can will slightly collapse. Add a hose full of sawdust, and the can all but implodes (see attached pics).
So, I scrapped the Rubbermaid trashcan, and tried a 20 gallon, "heavy duty" galvanized steel trashcan. I fabricated a second top for that, and fired it up. Same bad result. Any suction load, and the can would resoundingly collapse. Noisier than the Rubbermaid, too.
So, then I e-mailed Bill Pentz. (God bless him and his free sharing of expertise.) He suggested an internal bracing system comprised of circular disks with vertical dowels running through them. I think that would work, but I think it will complicate emptying the container.
I also posted on the Clearvue site, and another gentleman suggested stave type bracing. That might also work, but even with superior grade adhesive, that barrel will contract under load, and I am concerned that just about any glue would fail over time. After work, a buddy dropped off a used fiber drum with a lever lock lid. I can cave in the sides of that drum with medium heavy hand pressure, so I doubt that will work without bracing, and I haven't built it up as a prototype.
Now, I see why Oneida sells their Dust Deputy with a steel drum!!
Can anyone make some recommendations on a container solution?
1- a five gallon bucket is too small.
2- I don't have an old shop vac canister to cannabilize.
3- McMaster has a 20 gallon steel drum with no bung openings and a lever lock closing ring for $82, plus shipping. I'd prefer not to spend that much, if I can help it....
Also, as can be seen from the attached pics, I have already made up a rolling cart for the cyclone and vacuum, and would like to stick to something that will fit the cart and the hose runs, around 23" high.
Any input would be most appreciated.
