Emptying my shop vac was a chore I hated, and so I didnít use it much. I saw on you tube some one used a traffic cone to make a cyclone. I bummed a mikes hard lemonade traffic cone from a friend and made one. I didnít have much faith it would work untill I tried it. I cleaned the whole garage and it worked like a champ. I had made six bowls last week and tons of shavings. I am well pleased with it and now my shop should be cleaner.
