Introduction: Cyclone Vacuum Add on for Shopvac Updated

About: I have always like building... now I have the skills and equipment to do some really cool stuff.

Update: I am working on using three cones to see if I can use a bigger motor.

I should have done this sooner... been thinking about it for years. You can purchase all different kinds of attachments for all kinds of vacuums... but I wanted one for my shopvac. Being able to keep my vacuum sucking at it's best by keeping the filter clean... it's a no brainer.

So I needed a cone. I was driving around and trying to figure out how I was going to roll a piece of plastic and seal it off when I saw... a street cone. I know everyone describes these by saying... it's like using your vacuum attached to a street cone. Well I did it.

Street Cone (Big) $2 at Re-store
Various bits of wood $0
Drywall screws
Liquid nails or some other sticky gluey stuff (Silicone will work)
Shop vac
Shop vac hose
Shop vac extension tubes

First I needed some way to set the cone upright on my bucket, so I made this kinda box around it *(I was going to use milk crates because they are just cool... but didn't)

1. Cut two pieces of plywood the same size as the base of the cone
2. Cut Shop vac tube into one 11" piece and one 8" piece *(Approximate) The end of the tube with the flared end, the one that hooks to the hose went in the side.
3. Cut football shaped hole toward bottom of cone just big enough to shove tube in and have it not fall out. End of tube on inside needs to be close to the wall so the junk will slide around and then down.
4. Cut hole in the center of plywood pieces 2.5" for tube (top) and a 3.5" one for the bottom (outlet for junk into bucket)
5. On some cones there are little feet that keep it off the ground an inch or two. I cut these off.
6. Put a ring of liquid nails or something like it around the base of the cone and then screw it to the wood base with the 2.5" hole.
7. The other end of cone poked through the other plywood bit and I cut slits in the end, more liquid nails, then screwed it. (See image)
8. Made the outside wood supports and then went a little nuts with the miter saw.
9. Glue the longer bit of tube in the hole on the top... this tube has to go down farther than the side tube... it's a math thing.

Hook tube from vacuum to top tube and then another hose to the one on the side... Wallah

Overall this project was really easy and could be upscaled or downscaled for your needs. I will make some cart for the vac and the cone and I am done. Tested this and works really well *(See pic) I can use any bucket that is less than 14" across. I am wondering why vacuum companies don't do this with all their vacuums? Especially shop vacs that need the suction and keep the filter pretty clean.

Update: 4/2016
Still using and it works great. I am working on making it more powerful with more street cones and a bigger motor... maybe. Might just leave good things alone.
