Introduction: Super Easy Cyclone!

This is the simplest cyclone I could come up with.

Step 1: You Will Need

To complete this project, you will need a car cleaning nozzle and hose from your shop vac. A large bucket with a tight fitting cover. A straight coupling to attach your shop vac hose.

Step 2: Mark Placement

Mark the placement for your nozzle by tracing the nozzle. Mine measured about 3 1/2" long and was the same width as the nozzle.

Step 3: Cut Out the Spot for the Nozzle

Using a vibrating saw, cut out 3 sides.

Step 4: Glue in the Nozzle

Put the nozzle in it's place. Using a hot glue gun, glue the nozzle from the inside. Then, still using the hot glue gun, go around all the seams from the outside to insure an air tight fit.

Step 5: Install Top Coupling

Lastly, drill a hole in the cover. Be sure to make the hole the same size as the shop vac coupling. Placed the coupling in the hole. Using a hot glue gun, glue the coupling in place.

    It says to place the coupling in the hole in the top. But it does not have a picture from the inside. What I need to know is how far into the bucket does the top coupling go down?

    Is it only just enough?

    If it is lower than the inlet pipe is that better?

    very nicely done, this is the simplest one i have ever seen

    thanks godbless

    If you don't know by the name of it before opening the instructable you don't need it and have no need for it. No need to hate the author for your not knowing. Great simple little separator.

    i don't fully understand what it does and how it does it.

    Nice job!

    I made a similar one a year or two ago for my radial arm saw by stacking two spackle buckets. It does help keep bigger stuff like tiny wood chips out of the shopVac but not dust. After intermittent use over months, when I check the shopVac filter it contains dust like talcum powder, stuff that floats in still air. I stretched panty hose over the filter and that gets a caked on coating of slightly larger dust than the filter catches.

    I considered pulling the cycloned air through water like a water pipe, but I don't need it that clean. I have also considered removing the filter and venting the cycloned air outside.

    The best practical thing would be to make something that bangs the filter a few minutes after shutting down the shopVac. That way dust caught by the filter would fall away and have a chance to settle in the shopVac before the next use.

    Now you have me thinking ...

    Commercial systems use a blast of compressed air blasted into the filter (from the inside - i.e. reverse normal flow) - this shakes the dust off the outside. Have a look here: https://en.wikipedia.org/wiki/Baghouse

    Interesting. I'll probably start with an old baseball bat next to the shopVac to give it a few taps after it winds down.

    It's a nice idea, but is it really worth all the trouble ?

    It does not look like it would have the capacity to hold much refuse. I have mine hooked up to a 2 1/2 inch hose and its appropriately sized shopVac. If this had larger hose ports one could cut out its bottom and mount it on the top of a larger container. It would be nice to see if it has cyclone guts. Ash can be so fine I wonder how well it works.

    OK, here is a thought for you. The line going to the vacuum should be attached to the angled car attachment, not the other way around. When you have it the way you do, the vacuum is pulling the air straight up canceling out any cyclone effect you would get. If you hook the vacuum up the the angled car piece, it will create a cyclone & not be canceled out, and the air coming from the hose coming from the dust will be pulled into the cyclone effect.
