Thanks for the help. A customer wanted me to install a shower valve and I was so confused looking at this thing. The instructions say to sweat it to a copper pipe- but theres an O-ring on the inside! Instructions didn't even mention the set screw. Appreciate the guide.

fc im loving it thanks

Yikes you make this look difficult. 😮

You should always go in 1 direction when using this pipe cutter, not seesawing back and forth. The blade always follow the rollers, so the rollers will lead the way, and that should tell you which way to rotate it (depending on how you've put the cutter onto the pipe). Showing otherwise is NOT good.
