I am using just your basic 3 inch diameter PVC pipe. My problem is it ROLLS like there's no tommarow. I tried putting stoppers, towels, anythign i could to get it to not roll. I'm thinking that i should just cut the PVC pipe directly in half so i have two ten foot half circles that wont' roll. Do you think 1.5 inches up is enough to grind on without having ur foot hit the floor?
