I figure every one of these satellite threads needs a before after of my shop from chaos to order :)

The cleaned up shop has been in need of a basic dust management system for some time. The space is small, and needs to be multi-functional, so this system reflects those needs. I started with a 2 1/2 kit from Lee Valley tools. As you might guess, I only used part of the kit..the rest will go to my business shop.

After doing a 4" system at the office shop, I realized velocity would be much better with a 2 1/2" system powered by my Rigid vac at 179 CFM. To that kit, we add the Dust deputy. Trying things out on my table saw, I figure I should have sorted dust management out a long time ago. The dust deputy seems to end up taking 99% of the sawdust, meaning the vacuum suction stays much higher with a clean filter.

We have two of these Rigid 14 gallon vacs in two locations over the last 2-3 yrs, easily my favourite shop vac ever. They are relatively quiet, and move a ton of air. Looking over a few web reviews, they also seem to end up on top most of the time.

I wanted to keep things as simple, clean and compact as possible. The shop vac can be pulled out in seconds for use off-site, and the hose/attachments can be attached to any of the blast gates.

The Dust Deputy is tucked in behind the drill press. Hose is all 2 1/2". I bought a 50 ft roll, for both the home and business shop.

The vacuum ends up sucking up almost nothing:

The cyclone bucket though is pretty full:

Analog Vaccum Controller

If you want an effective vacuum control using two circuits, this works well: http://ivacswitch.com/ivac-switch/ You plug the tool into this box, and when powered, it fires up the vacuum. It delays the vacuum power off by about 5 seconds to clear the lines. It can draw power from one or two 110V circuits...two being the preferred set up if you're drawing more than 15 amps for the vacuum and tools.

Fancy pants Automation Control of Vacuum

I decided to try my hand at writing a Smart App, and using automation to run the vacuum. If you're interested in setting this up for yourself, I posted the code, and instructions over at the SmartThings forum. You'd need a Smarthings Hub (about $100), the app I wrote, and a few smart plugs to make this work. Being that I already have the garage automated, the incremental cost was low.

Using this type of control, you don't need to run extension cords from a device like the iVac switch for each tool. You can also have more than just one device controlled using the Smart app..and you can set the turn off delay to whatever you like.

This Zwave receptacle can be controlled via Zwave wireless. The automation hub communicates with the controlled half of the receptacle, and switches it on and off based on what the Smart App I wrote tells it to do. The Rigid vacuum is connected to the controlled receptacle.

This Aeon-Labs-DSC06106 Smart Energy Switch reports energy use to the automation hub. So if a tool is connected to it, and powered up, the switch communicates the power increase to the hub (via zWave wireless) which in turn powers on/off the vacuum. This means you can plug any tool into any circuit, and the vacuum will turn on/off automatically. The downside to using this app is that there is a bit more delay than when using the iVac switch.

A close look.

looks cool. I'm big into automation, but I probably would have left the vacuum controlled by 1 or 2 switches for simplicity.

JG, I'd agree. The iVac solution is pretty much instantaneous on, so a better choice for tools like the chop saw which are on/off in some cases for only a few seconds.

Smarthings does some select local processing, but custom apps and device drivers etc. run in the cloud. So while the learning process on the automation side was fun, the KISS rule generally prevails :) I also use a Vera hub in a different location, which would likely be much faster with this application...however it doesn't support Zigbee.

One nice thing about automation in the shop, (other than the security side of things) is that my house routines also power off all switches etc at night. I've made the mistake of leaving lights and/or heat on in the shop before (sometimes for a day or two), so this "master off switch" is where the automation bits are most useful IMHO. I've also had the roll up door reverse on me after leaving, so the open door scenario prompted integrating the shop.

I have about 30-50 programs running on a ISY controller for insteon devices. I run a 2am "all lights" off program for the same reason.

Jg, I'm using SmartThings at home, and Vera Edge at the office. The market is ripe for an approach like SmartThings with a developer community firing up simple apps (with a sophisticated web based IDE) but using a controller with 100% local processing. Cloud based processing seems like a rather large violation of the KISS rule :)

Last I looked no one was able to get the energy reports to work with the Aeon outlets through SmartThings. Did something recently change?

How big have your pressure drops been? Mine have just about made my vac useless and has me wanting to just get a real dust collector. Here's the results I was getting

Love the shop and your ideas. But that much draw between the tool and the vacuum is hard on both tools because of the voltage drop. I have to assume there is a delay for starting the slave receptacle but if not that start up current is going to lesson the tool life of both.

I could however see a great solution with that program and the devices if the control scheme can be easily programmed. That being the tool on a dedicated circuit and the vac on another, is that possible with that system?

Thanks, Cam


Maybe I should have read the operating description before I asked. Looks like it has the start delay, but regardless it's made for lower horsepower connected loads. Still a cool idea.

Oh one more question. With the KW monitoring can you isolate the actual voltage and current reading through the Zware software?

Cam, thanks for the kind words.

There are 20 amp zwave switches out there..and an lfm-20 zwave relay is good to 20 amps at 220V. Both vacuum and table saw max out at 12 amps at 110V currently.

The automation delays the power-on by virtue of latency (1 to 2 seconds)...and I'm using all the devices in separate circuits, albeit all at 110V. It would be easy to program more of a delay, but I'm guessing the automation latency is enough. The iVac switch is ok for 30 amps via two circuits at 110V... about .5s delay there.

There are a few different device drivers you could use for the AEON, however all of them display watts. They obviously need amps and volts to calculate wattage, so my guess is that you could uncover these via device code tweaks.

Thanks for the post....I'm just about ready to do something like that in my garage....the sawdust is out of control.

The wife for Xmas bought me the Rockler dust buddy can. I'm about to build a new base for my table saw and make that a part of it.

Hence, I'm thinking of using the table saw as the main dust collector...and when I use the radial arm saw....run a hose over to it.

But....that is subject to change. I'll have to look at the big picture

Nice set up! I'd like to add a suggestion that long term you switch to a small wall mounted dust collector for that system. Very compact and moves a ton more air than any shop vac. About 90% quieter too! I have this wall mount shop fox system and it works great! With the two micron bag you can eliminate the dust deputy and get the whole thing up high and out of the way.

Crooklyn, copy away :)

LX, you're quite welcome.

John, good luck with your system. Just remember the KISS rule :)

John, thanks! I did look over that unit and checked the reviews. I was very tempted to give it a try, but just figured I'd try the Rigid as it was matched (if anything a bit too powerful) for the standard DD. Can you comment on what you like/dislike about it the Shop Fox unit? Feel free to post pics here if you'd like. My system at work might be a good candidate.

I've had zero issues with the Shop Fox wall mount unit. I have it mounted high up on my 9' garage walls with a 20' Rockler expandable "dust right" hose. I use it mainly to capture dust and shavings from my pen making mini lathe, but I also use it on a band saw, table saw, and 12" disk sander; all with Rockler dust right hook ups. The Rockler system also has a nice floor sweep and bench brush to make clean up easy.

The only issue I've had stems from when I turn acrylic encased carbon fiber pen bodies. The endless ribbons of acrylic shavings sometimes bunch up in the 4" inlet to the collector. This requires removing the hose and manually cleaning out a ball of shavings. All other wood shavings pass right through. I'll try to post up some pictures of my set up later. I have a wireless remote (xmas light kit) to remotely turn on the DC.

Edit: here are some pics.

Here is the wall mount and remote switch. Ignore the large conduit, that's a 220v line going to my Jacuzzi.
