no previous part Part 1 of Dust Collection - Table Saw and Router Table series Part 2: Vacuum Valve »

Two of the biggest sawdust creators in the shop – tablesaw and router. I have dust collection of a sorts for both of them, but it is primitive. I have a small length of 2 1/2” hose that moves from one tool to the other and no autoswitch. So, first I move the hose connection, then I turn on the vacuum, then I can run the tool. The only filtering is is that inside the shopvac and those suckers are $14 each! I need a better solution.

I have been reading about vortex dust separators for a while. Of the mini separators, the Dust Deputy is the cheapest but gets consistently high marks in shootouts with the others. I ordered one.

A friend of mine gave me three of these barrels:

It looks like they originally held 100 lbs of powdered hand soap. Very sturdy, cardboard construction (important because I want to add some sensing to tell me when the container is full), and did I mention sturdy. I have seen reviews where they actually collapsed 5 gallon buckets with the suction from a shopvac. I use two of these for waste buckets around the shop.

The metal ring that originally sealed the top keeps the garbage bag from collapsing into the bucket.

I took one of the metal lids, cut and drilled mounting holes and mounted the Dust Deputy:

The lid is heavy enough that I didn’t need to add any support. Some posts on the Webb using 5 gallon buckets had to add a plywood circle to support the Dust Deputy. I don’t think it will be necessary in this case but I still haven’t put any vacuum on it.

So here’s what I have so far:

And, of course, I ran into my first problem: the Dust Deputy is designed for 2” hose. All the hose I have and every shopvac I have are 2 1/2”. I’ll have to find a way to adapt the Dust Deputy to 2 1/2”.

I have big plans for this. I want to automate the dust collection as much as possible. That will involve making an autoswitch that will turn the vacuum if either the tablesaw or the router is turned on and some kind of diverter valve that will automatically switch from one tool to the other. I also want to add a sawdust sensor to tell me when the dust collection bin is full.

Stay tuned!

you can purchase adapters to fix your hose to deputy, I just cut down a vacuum ‘wand’ it had a taper to it and….well it worked. If you search this site you can find ‘blast gates’ to isolate your machines. All the major WW supply places carry them as well as the remote switch. The dust deputy really does do what it was designed to do, and does it well.

I have used a shop vac and separator for years and have been very happy with it.
I ran a hose from the separator to the shop vac like everyone else does. Then for the intake side of the separator, I ran a line to a manifold made up of 5 Y’s, each with a blast gate, and ran hoses to each tool and one hose coiled up for shop cleanup.
I just open the (one) blast gate and I’m ready to make dust on that line. I did put labels on the gates (‘cause I confuse easily).
my new shop (under construction) will have 4” ducts and a for-real dust collector using a very similar set up.

I’d like to add my two cents (with today’s inflation. I’m sure it’s worth almost nothing!) I’ve had my dust deputy for about a month now and I still can’t understand how something that simple works so well. All the reviews you’ve probably read were absolutely true. This thing is amazing. The biggest problem with mine was that it was always falling over. I cured that problem by making a cart for my shop vac/dust deputy.

Of course, you won’t have that problem with that big honking drum! My shop vac has a 2 1/2 inch hose also, but it can connect to the dust deputy just fine. If you notice the input and output are both tapered so that they can adapt to more than one size hose. As I bought mine as a complete kit, mine actually had an o ring that would help seal the 2 1/2 inch hose, you might want to try that.

As for the auto switch, I’d like to have one too but they are a little pricey. Have you considered trying a remote control outlet adapter? You can get one pretty cheap and while it’s not an auto switch by any means you could still turn your vac on and off remotely.

Well, that’s the next thing: test it! I’ll try and cobble something together by this weekend. It is nothing that a hundred others out their on the web haven’t done, but I gotta see it for myself.

As for the auto switch, I’d like to have one too but they are a little pricey.

I designed my own working on dust collection for the miter saw. There’s some discussion of it over here

I will probably use two copies of the same design on this.

EE, +1 on Jimbo’s suggestion of the remote switch. I’ve been using the X10 20 amp remote switch for my 2hp HF DC for over a year, and it works fine. These are available on eBay as well, very reasonably priced. Each switch has a unique address and the remote controller can select the address/device to turn on or off.

Naaaw, you just don’t understand. The more difficult it is to use dust collection, the less likely I am to use it.

My goal is that I walk up to the machine, turn it on, and whatever attendant dust collection automatically powers up to collect dust. And I am not gonna string 4” or 6” hose all over my shop to get to a central monstrous DC. I am more a fan of small dust collectors attached to each machine individually (see my miter saw dust collection here). I think you lose more efficiency in the long runs of hose – in fact, I’ll have to look it up: how much loss do you get in a 20 foot section of 4” pipe versus a 3 foot section of 2 1/2” pipe?

At any rate, my goal here is a simple two-machine (table saw and router table) dust collection system. When it is done I expect it to:
1. switch on automatically whenever either of the two tools is powered on
2. detect which tool has been powered and direct the dust collection to that tool

And, incidentally, I want it to tell me when the drum is full and needs to be emptied. Everything else I have figured out, this one is a little tougher. I work for a sensor company and have several capacitive sensors – something we sell to people who need to detect sawdust. But I have to play with it a while – I don’t know whether I can reliably detect sawdust through the cardboard drum. I know damned well it wouldn’t work through a metal drum but I am pretty certain it would work through plastic buckets. While I am bringing this design up I will test it all.

OK, sounds like you have the requirements nailed, so I’ll watch with interest to see what you come up with!
