Take a look at this, which is the one I have.

You can use two separate circuits, so you have less likelihood of an overload.

Per Jakkarth, Bench vice... first thing that came to mind. maybe a bench grinder. Does he have a good shop vac? Dust extractor? Maybe this w/ a shop vac.

Hi there, I’m not a tradesman, but could this be the device you are searching for?

I love mine too. Here's the link for anyone who is interested.

Holy crap, I never saw either of the mods you linked (probably a good thing) since I don't have the space to do all that. Good idea to go with the clean out ports. I wish I had considered that. I probably made a bunch of mistakes in mine, but it's a work in progress (that's my excuse anyway). I have everything pretty tight, as in close together. Small drill press, router table / table saw combo ala Incra, disk/belt sander, small Rikon bandsaw in the non-laundry room part of the basement.

I have 9' x 12' wall to wall space to work with so when at the table saw, my HF workbench is less than 2' behind me so I really only need to turn around for that. The router, table saw, sander, and band aw are each on their own 2" PVC drop with blast gates at each. 1st mistake was the 2" PVC. I should have never done less than 3" and wish I had more. I was getting a shitload of dust with the smaller HF DC, but I'm getting much less now.

I bought a WEN air cleaner and love it. I really recommend you consider it. It's really kept the small stuff from getting everywhere. Since that fine dust everywhere was a big issue for the spouse, it was an easily rationalized purchase. Noise is the big issue now. As I said, I have the exhaust ported out a basement window like a dryer vent into a window well. Not optimal, but serviceable. As you can see here, I have the new louder DC under the table where the sander and bandsaw are sitting. I'm looking at 'boxing' it in with something, but not sure what I'll try 1st. I wonder if active noise cancellation would help.

As to auto switch, I thought about it, but everything is so close I can almost reach the remote switched outlet for the DC from anywhere, but it had me looking and the iVac was about all I saw commercially. I did see some DIY breadboard builds though. Thanks for the write up. (*Edit) There seem to be a lot of videos on modding the HF model, but that Rikon impeller is not cheap if you can find one.

Using this strategy, you can probably put this together with off-the-shelf components. These type of relays are common for dust collectors for saws (i.e. turning on a central vacuum whenever the saw is turned on).

Something like this:

They undoubtedly make them for higher amperage saws as well. Looks like OP's machine might be a 20 or 30 amp plug.

Plug the machine into the "saw" socket, plug a lamp with whatever color bulb into the "vacuum" socket, all set.
