Years back, I was doing work on the oldest Queen Ann in Olympia, Washington. One of the projects was cleaning up the cedar siding and shingles in front. To remove the paint, I was using a Paint Shaver Pro, which is like an angle grinder, with which a head that has three triangular carbide teeth that remove up to one square foot of paint in about one minute. Needless to say, the beast throws off a lot of dust and debris.
Initially, I ran a 16 gallon shop vac with a HEPA filter. Run time between filter cleanings was about 5 minutes. Obviously, a pain. More so because you had to be careful with everything, since the place was 80 years old, so most the paint was lead.
On a whim, I build a poor mans Rainbow vacuum using a 30 gallon, plastic drum. The pipe from the Shaver went to the bottom of the drum and the one to the vac stopped just inside the lid. To knock down splash and such, I fit a 3-M floor scrubbing pad in the drum, with a single hole for the pipe running to just off the bottom. I added about five to seven gallons of water and tried the process again. Run time went up to 20 minutes, but what a mucky mess.
I was looking for a better solution and came across a contraption called a Dust Deputy. It sounded good, so I took the two hundred dollar plunge (metal version, for the abuse factor) and have never looked back.
The Dust Deputy also gave me about twenty minutes of run time, but without the muddy mess. Add to that, it kept the efficiency of the vac high enough I was able to drop back to a smaller vac.
The Dust Deputy inspired the purchase of a 3 horse Gorilla for the shop, and Super Dust Deputy for one of the four bag units and another Deputy for the sandblast station.
I had a separator with the 90 degree bends, like the ones in the photos, but was unhappy with the results. That is not to say it didn't help, but the cyclone efficiency spoiled me. That aside, a couple of the other units show do seem to offer promise.
Meanwhile, I love that, whether using the DD, the SDD or other cyclone, I only have to empty out the dust collector collection bags about every five or ten years, though I may have emptied the drum fifty or a hundred times.
The reason I have what you want is, I never lent it out before.
Scraps are a myth.
