Make a cart for your Dust Deputy
I love Oneida’s Dust Deputy, and I said as much 2 years ago in my original review of this mini-cyclone dust separator that attaches to shop vacuums. It keeps the shop vac empty, its filter remarkably clean, and the suction super-strong. But bolted to the side of my vac’s canister, it was an awkward appendage, tipping constantly as I tried to wheel the whole shebang around the shop. I’ve always intended to make a cart that would support both units, and I’ve see a number of designs for those.
But the one I made this weekend is simpler than anything I’ve seen. It took a single scrap of 3/4-in. plywood and a few bolts and screws. So it cost me nothing, and took about an hour to make!
The cart came together after a couple of brainstorms. One is that I could take the wheels off the Shop Vac canister, and simply screw the canister and Dust Deputy to the plywood. That works because the Dust Deputy sits on two 5-gal. buckets: One holds the dust and the second bolts to your shop vacuum and holds the first bucket. And I could screw down the Shop Vac because it stays so darn empty. When I do need to empty it in about a decade or so, I’ll just stick my dust-collector’s hose in there.
My second bit of Yankee ingenuity was re-using the cart-style wheels on the Shop Vac by screwing them to the bottom of the plywood and continuing to use the big handle atop the Shop Vac to control the entire cart!
It works perfectly. If your shop vacuum doesn’t have a big handle on top, you can attach a piece of plywood vertically between the bucket and canister, with a handle cut out at the top, and then use that to wheel the cart around.
By the way, I also put a couple of small sheet-metal screws through the connection between the dust hose and the Dust Deputy’s inlet. That hose always tended to pop off. Now that problem is solved too.
This is my simple but effective cart, just a slab of plywood, with the Shop Vac's wheel set screwed on below. It works like a charm, turning my awkward old setup into one graceful unit.
Since so little dust ends up in the shop vacuum, you can just screw it down to the plywood. Do the same to the bottom bucket under the Dust Deputy.
To get the two units closer together on my plywood cart, I rotated the Shop Vac a bit so its hose cleared the Dust Deputy bucket. This meant I had to reposition the Shop Vac's handle. I plugged the unused bolt hole with a flat-head screw, driven into a little piece of wood inside.
I cut the Shop Vac's wheel assembly apart, and found a way to bolt and screw it to the bottom of the plywood. Nothing wasted, no money spent!
I used to have the Dust Deputy bolted on in the standard way. But even after I attached a little foot to the plastic bucket, the whole thing was so tippy I just left it in one place in my shop.
