Thread: Shop Vac cyclone

  1. #1

    Shop Vac cyclone

    Here is thr mini cyclone I just built from scrap lying around for the top of my Ridgid shop vac. It's built the same way as the cyclone I just made so I didn't feel he need to repost them again.

    I'm using the motor mount plate to rout a groove for the filter to sit in. The piece on the bottom is what the filter will mount to.

    Here are some pictures of the assembled top for the shop vac. I still need to attach the pvc pipe from the top of the cyclone to the filter box, rout a groove for some weather strip to seal the top to the bottom of the vac and make a transition on the input to connect the hose to.

    Very cool Alan. Is it the filter rod that hold the vac motor on? Very compact little unit.

    Glen the motor is held in by these 2 tabs that fit into the groove I cut in the top and a swivel lock I still need to make and install.When the unit is running the suction holds everything tight.

    Here is a shot of the inside and how the filter is held on.

    I also made my own fittings from some pvc pipe I had laying around I brought home from a job.

    This is how I did the seal for the lid. It is 1/2" backer rod I had laying around. I used a 1/2" cove cut bit in my router with a circle cutting jig. The ends are glued together with contact cement and it is a friction fit in the groove.

    I tested it with some red mulch since I only have a used filter right now. The mulch was in the container and no signs of it were in the filter housing.

    It might not look very pretty but it works and I made it without buying anything which was my real goal.

    Rennie, You thinking what I'm thinking? Of using this with the dust deputy?

    Can't wait till mine gets here.

    Thanks for the awesome photos Alan!

    Looks like you nailed it Alan, great build!

    Now you got my gears churning, Alan. My Shop Vac brand vacuum has a pull-out mini-vac...it's essentially the big motor with a smaller filter and small (2 1/2 gallon) bucket. I'll have to study things and see if it could be modified to do something similar to yours when I get the Dust Deputy. I like the idea of a more compact form factor like yours.

    Well I was going to leave it alone but this little vioce in my head said to go out this morning and finish the job right. So I went and rounded of the corners and sanded everything flush and applied 2 coats of lacquer. The cyclone I sprayed with flat black primer. Sure makes a difference and looks a little more professional now.

    To keep the hose from falling of I folded a piece of metal in half and soldered it to the transition I fabricated to give the catch on the hose a place to grab.

    This picture will give you an idea of the finished height of mine. the nice thing about it is it doesn't take up any additional floor space and converting it back to a wet vac is as simple as removing one top and reinstalling the other.

    That is just so cool. I am definitely going to work something like that up when my mini cyclone arrives...
