Dust Collection Upgrade

Oneida - Super Dust Deputy (Rating: 5)

I have wanted a two-stage dust collection system for some time, so decided to take the leap and order an Oneida Super Dust Deputy.

The Super Dust Deputy (SDD) was well packed and everything (SDD, installation bolts, foam gasket, and the 5"-to-4" and 6"-to-4" reducers) was packed in a single box surrounded by plastic and foam. Because of the lid I opted for, I substituted the bolts Oneida provided with 1/4" x 20 tpi x 2 1/2" that I had on hand in the shop.

Oneida offers a barrel that is made for the SDD, but I opted for a home-spun solution. I laminated two 20" x 20" x 3/4" sheets of MDF together, and used my circle jig to route a 3/8" groove that matched the inside diameter of a 20-gallon garbage can. I installed a 3/8" wide by 1/4" thick strip of foam insulation in the bottom of the groove.

To make it mobile (I still like pretty much everything on wheels in my shop), I made a base out of scrap lumber and attached casters to it.

The lid fits snug on the can, but for extra security, I installed eye-hooks on top of the lid and on the base for a set of bungee cords.

I turned some scrap stock on the lathe and made a pretty good-sized pile of shavings which I then sucked up with the dust collector. Nothing detectable would up in the bag, and the pile was relocated to the bottom of the can.

I don't have any empirical data, and it does seem that I have a little less suction, but I think that is to be expected, particularly when using reducers to accommodate 4" hoses. I think the loss in suction is offset by getting less in the filter and not having to empty the DC bag quite so often.

BTW, the dust collector shown is a Jet DC650A that I picked up on CraigsList for $50. I added the PSI canister filter (~$130) last year, and bought the Super Dust Deputy and reducers for the SDD inlet and outlet for ~$220 plus S&H. My total investment, including hoses, fittings, etc. is in the $460 range.

Down the road, I will probably replace the dust collector with a more powerful unit, but for now, I am pretty happy with it. And my future plans include moving the SDD to whatever new configuration I come up with.

I have been thinking about the wok mod … maybe I'll do that next.

I just ran a bunch of stock on the tablesaw and cut a batch of pen blanks on the bandsaw … nothing in the bag at all. When the DC is running, I'm not seeing the familiar tornado in the bag.

About 1 year ago, I upgraded my DC to include a SDD separator (and you will loose some suction, simply because you've placed something else into the air stream), and I can say it is one of the best investments I've made. I've also added a Wynn Environmental HEPA canister onto the 1.5hp Delta. I have a HD trash can sitting below the SDD, and it accumulates the vast majority of the debris and fines.

I fully recommend this upgrade.

Gerry, I am thinking of doing the very same thing. I have a jet 1.5hp DC, and have been thinking of selling it and getting the well reviewed Harbor Freight 2hp (should be ~even exchange). The thing that I noticed in your setup that may be causing a decrease in suction is the piping. If you decided to leave the DC in one place, then you could use the slick metal pipe. This way you may be able to gain some of the suction loss back from "simply having something else in the air stream". Just a thought; it might work.

Nikki-Actually, you are right. I didn't think it would make sense to use piping on a 650cfm dust collector … I just drag the hose from machine to machine. If/when I upgrade to a more powerful DC, I will probably run PVC lines to them.

Joe-I also have a plastic Dust Deputy that I use with my shop vacuum … been using it for about 3 years. I have been really happy with the products I purchased from Oneida.

I built a Thein set-up (http://www.jpthien.com/cy.htm) to attach to my HF dust collection. I've used it for over two years. It does a great job but I get a lot of caked dust in the canister filter and it is difficult to remove the trash can holding the dust.

Can you compare the Super Dust Deputy to the Thein design? Is the suction about the same? Do both remove the same amount of dust?

Thanks in advance. Good review.

Nice job Dane!

I added the Wynn filter and SDD to my HF unit at the same time and noticed an increase in air flow. I've heard before that the SDD will decrease air flow and the Winn filter will increase air flow over a bag (more sq. feet.) So in my experience the increase from the Winn filter change more than offset the decrease from the SDD.

I have made quite a bit of saw dust and chips this week, including some plywood and MDF, and still nothing in the bag. Looks like the SDD is doing a good job. There is a slight loss of suction (I notice it most in the overarm guard on my SawStop), but I can live with that. Contrary to some of the opinions voiced above, there is no way I will consider replacing the hose with piping so long as I am working with a 1hp / 650cfm dust collector.

I wish Wynn made a MERV 15 filter that would fit my dust collector. The Jet DC650A is much smaller in circumference than the HF (and most other) dust collectors.

The only filter I could find that was close (without having to cobble up adapters) was the PSI 1 Micron model.

Still better than the 30 micron cloth bag!

The plastic version wasn't available yet … they introduced it a few weeks after I bought the steel SDD.

Had the plastic been available, I think I would have opted for the steel anyway. Down the road, I would like to mount a more powerful blower (like the PSI 2hp blower) on top and I think the steel SDD might be a better fit.
