Hi, got a question about my shop vac, I can find no specs on it must be discontinued sears don’t list it any more and can’t find one on ebay either. I have a Craftsman 8 gal shop vac, I did find it is a 9 amp and 3.5 HP. 1 1/4 inch hose. I want to build a dust collector for it.

will it have enough power for a dust collector to work, I noticed on the utubes they all use at least 2” hose. will my vac work with 2” hose or will it cut down on the suction. a larger vac is not in the cards. I don’t expect an increase in efficiency but it will make emptying the vac less messy. Thanks Mike

It all depends on what you want to use it for. For example, it’d work for a pad sander. For things like table saws, it would help, but would only reduce the dust being kicked off.

ok, It works for my Table saw ok, keeps a good amount of the dust down. Im not asking a lot. I will only use it for my BS TS maybe lathe, one at a time not on a system

I believe that vac came with a 1.25” hose with a 2” end fitting, so the vac inlet will take a 2” hose; correct? Should do fine using it on one tool at a time with the 2” hose. Just don’t go overboard on the size of the collector relative to the size of the vac.

My dust collection ‘system’ is very basic and consists of a similar Craftsman 3.5 hp / 8 gallon shop vac that I attached to a Dust Deputy connected to a five gallon bucket. While I would like a bigger and better dust collector, my budget priorities have been focused on obtaining the other items in my workshop and with the hope of finding a good buy on a canister filter cyclone collector.

I presently use my ‘system’ on a Laguna 18BX bandsaw and a Grizzly G0490 Jointer with a 4” flexible hose that adapts down to 2” and into the Dust Deputy; a Ridgid belt/spindle sander, scroll saw and router table that I run into the Dust Deputy via a 2” hose; and I use the smaller hose on various handheld power tools as well as for general shop cleanup and floor vacuuming which also flow through the Dust Deputy.

It is amazing the difference the Dust Deputy makes and on my last clean-out, there was perhaps a handfull of stuff in the shop vac (much of which I think was there before I hooked up the DD), while the 5 gallon bucket was mostly full – and the filter itself was remarkably clean with just a little accumulation that I blew out with an air hose. I noticed very little, if any diminished flow with the vac, whereas prior to the Dust Deputy, the filter would clog quickly and result in much less power.

While my system is far from perfect, it does a really good job collecting from each of my machines (there is very little accumulation in each) and I am getting by quite well until the time comes that I can afford something more.

(Sorry for the sidways photo and it shows up okay on my laptop, but got itself twisted somewhere in cyberspace.)\

2” hose will work fine and will actually make it easier to suck up larger chips and such without getting stuck in the hose. The dust separator will reduce the suction (20%?) but the added convenience of having most of the dust in the external bin rather than the vac and filter will be worth it, IMO. Are you going to buy a cyclone separator or just make one like some of the Youtubers do out of buckets?

BTW, I highly recommend a Cleanstream filter for your vac. It is more expensive than the standard ones but because you can clean and reuse it dozens of times it will save you money. Get the wet/dry version so that you can wash the filter. I bought mine at HD a about 4 years ago and it is still going strong. I only clean the filter about every 4 or 5 times I empty the dust 5 gallon separator bucket.

Hi thanks for the suggestions, its is good to hear from somebody who has the same vac as I do. I like the separator I dea. would, it work with my 1.25 hose. I would rather do that because I would only need to buy one hose. your set up looks good thanks mike

I was going to make a cyclone from a bucket. Thanks for the filter suggestion. I saw a cloth filter bag for shop vacs that looks good, it goes over the filter to keep the dust from clogging the filter. But I can’t remember where i saw it

I bought a Paint Shaver Pro for a paint job I did on the oldest Queen Ann in Olympia, Washington. It required a vacuum to keep it cool. Of course, the dust it kicked off needed to be tended too.

I ran it on my 16 gallon Craftsman and would get less than five minutes run time, until the fine dust clogged the filter and it had to be cleaned. I knew that wasn’t going to work, so I found 30 gallon plastic drum and made it into a Rainbow vacuum type separator.

The barrel was about 18” across and it was about three feet tall. I built a sealed lid for it and placed the inlet and outlet pipes in it. The one from the pick-up nozzle went to about 1-1/2” off the bottom and the other, ended just past the top.

I used a 3-M scrub pad for a floor polisher to make a baffle (a hole in it for the single pipe to the bottom). It floated on top about 10” of water.

Everything drawn in had to go through the water, past the baffle and over to the vac.

It worked great. It extended run time to about a half hour. However, the contraption would foam like a banshee and the sludge was a mess to get rid of.

I found some weird thing called a Dust Deputy [cyclone] and figured if the hype had any merit, $200.00 for the metal version would be cheap. I got it, it worked and I’ve never looked back.

The Dust Deputy works so well I was able to drop to a five gallon, “7 horse” Ridged vac and the sixteen waits around to pretend it’s an electric leaf blower.

Because of the efficiency of the Dust Deputy, I bought a 3 horse (240 VAC) Dust Gorilla and a Super Dust Deputy [SDD]. The SDD wheels out to the yard with a Harbor Freight collector I bought for that purpose and cleans up pine cones and leaves. I’m also thinking of a SDD XL for the four bagger lacking one.

I used to use a cloth bag filter for years before the pleated filters became common. The problem is that they clog quickly and they have less surface area than the pleated ones so I think they need to be cleaned more frequently. My 2 cents.

true but you only have to shake them out, pleated filters you have to shake and beat till you get the dust out very messy

Not the ones from Cleanstream. Because of the Gore material they are made from, much of the dust will come off just by tapping or bouncing the vac, even without opening the vact to remove the filter from the vac, especially when they are new. After about the 10th cleaning, the dust does not tap off as easily so I just rinse them off with water which eliminates the dust completely. After seeing how well they work, I will never buy a traditional pleated filter again, much less a cloth one.

I have an almost identical setup to what BattleRidge showed (‘kept my vac is a ‘70’s craftsman).
It does work well with the DD, getting nearly zero dust into the vacs tub (used for a ROS so really fine dust).

There are a number of cyclones out there from expensive stuff like the dust deputies to cheaper separator trash can lids, do a search on various reviews. The goal is to keep the sawdust away from the vacs filter so you are not cleaning it constantly.
