How many of us have purchased a cyclone pre cleaner for our shop vacs? What a pain in the butt right. The cyclone keeps falling over...... I have a very simple solution: 1) Take the wheels off of both the shop vac and the cyclone. 2) Cut a piece of 1/2" plywood large enough to hold the shop vac and cyclone. 3) Find a nice 5 gal. pail, one that the cyclone will drop into. 4) Screw both the shop Vac and pail to the plywood. 5) Put at least 3 wheels from the cyclone on the bottom of the plywood. 6) Drop the cyclone in the bucket, hook up the hoses. Now you have a very mobile unit that will not tip over and the cyclone is very easy to clean out. Enjoy.... I've add some pics, you can see the working model as well as the parts that are involved. The caster came off the Tornado bucket. With the hoses on the Tornado bucket it barely could stand up on it's own.
