Query: serious pipe cutter!

I love Lenox. When they make a cutting tool, they don't mess around. This pipe cutter is rock-solid. I've used it on 1/2" to 2-1/2" pipe--cuts everything well. This is the tube cutter you want for a lifetime. My yet unborn grandchildren are likely to be using it.One concern I had was using it with thin-walled PVC pipe of large diameter. This kind of pipe will tend to deform as you tighten the tool. It works fairly well when you are cutting from the middle of the pipe, but the deformation is too much at the end. But I found if I stuck a ring of pipe inside the pipe you were cutting, it would give it the extra support so that you could even clean cut the ends. To do this, take a scrap piece of pipe of the same diameter you are cutting, and then snip out a longitudinal section with a pair of good scissors or tin snips. Then it will squeeze into the pipe you need to cut, and give you the extra support you need.A fast, mean clean cutting machine.
