I wanted to share a design for integrating an Oneida Dust Deputy and a shop vacuum.

I got part of this idea from a picture I saw on the Oneida web site a couple of years ago (since taken down). I like it because it is compact and keeps the otherwise unwieldy mess from flopping around.

My big insight is that you don’t actually need a super vac to run the cyclone. Since the cyclone and bucket collect virtually all of the dust, the dust bin on the vacuum itself is almost rendered unnecessary. So why use a 6 or 16 gallon shop vac when the smallest size will do? Also, I knew from experience that my 6 gallon shop vac (3 HP, 143 CFM) was plenty strong enough to run the cyclone.

So I bought a $30 shop vac from Lowes (2.5 gallon, 2.5 HP, 130 CFM) and rigged up this cart, which is made out of a quarter sheet of ½ inch plywood. The vacuum is mounted on its side in order to get a smooth hose run from the intake port to the top of the cyclone. I used screws and nuts to bolt the bottom of the vac to a piece of wood that acts as a cleat to mount it to the cart. Because wet/dry shop vacs have a float that protects the motor from water, I disabled this feature by cutting out the float. Otherwise any slight tilting and the suction could be lost.

The cart is put together with pocket screws, although any type of joinery could be used, and if it was made with ¾ inch plywood the butt joints could be screwed together directly. I used ½ inch ply because it was lighter and cheaper. The casters are just reused from those supplied with the shop vac. I used the ShopVac 3 piece adapter kit to make the transition from the 2.5 inch hose to the 1.5 inch that attaches to the vacuum. I had to soften the larger hose in hot water a bit to get it to stretch over the adapter.

The cyclone assembled this way works great. It has plenty of suction to collect chips and dust from a router, a chop saw, or even a 6 inch jointer. The only thing I don’t like about it is that the on/off switch of the ShopVac is a little difficult to use, but I am in the process of replacing it with a toggle switch.

Hope you find my idea useful.

Nice work, I had built one of these on here a while ago as well. Just out grew it and put in a central dust collection system that is hooked up to all the tools permenatly. Great idea and nice plans. A great post to help the others out there who use this set up!

Great idea, and good instructions. Food for thought for all the workshop owners.

What are your hose size diameters? 2.5 going to a 4? Or, is the 6 hp vac a 1.5 hose going to a 2.5? Kind of hard to tell from photo…

Nice job. I appreciate the plan detail since I have been sketching a couple of concepts for my set up. Can’t complain about Oneida too much… it works for me but it is an unwieldily set up. I leave mine in one spot and use very long hoses… and that is not the bast answer either.

I do have a wireless remote hooked up to it so I don’t have to reach for out of the way switch. That works really great. Found the remote at either HD or Lowes for less than $30 and it is rated for this application.

I love it. I have the Dust Deputy too, but mine is on a big barrel. I should put both of them on a cart like you did. Nice going!!..........Jim

dustyal – The hose from the vac to the adapter is 1.25” and comes with the vacuum. The hose from the reducer to the top of Dust Deputy is 2.5”. The hose coming out of the side of the Dust Deputy is also 2.5”. The 2.5” hose is Item #: 71994 | Model #: 9050311 from Lowes. I agree that a remote start would be helpful. Not so keen about the long hose, though, mainly because I’m afraid that one day I’d trip on it.

Ken90712 – I have an Oneida mini Gorilla that works very well but I haven’t built the piping to distribute the vac to each work station so I just use it for the tools that are near enough to reach with the 5” flex line (TS, router table, planer). My idea with this was to have a couple of inexpensive DD/Shopvacs around the shop to collect from the drill press, miter saw, handheld sander or router, etc. as they are used on an occasional basis. Also, these portable DDs are great for vacuuming up debris from upstairs renovation projects, since for some reason my wife doesn’t like me using the household vacuum cleaner for this!
