Now, the pipe is sticking out like a sore thumb, flush against the stud or tile. Your mini cutter will fit, but there’s a trick: you can’t spin it full 360 degrees if the wall is in the way. So, you’ll spin it only as far as you can—say, 270 degrees—then back it off, reposition, and keep going.
Pretend you’re dancing the forbidden tango with a copper snake. You twirl, you back off, you twirl again. After a dozen rotations, you’ll feel the pipe start to yield. Don’t stop until the blade bites through, or until your arm cramps. Then, give the pipe a gentle snap with the tool and it’ll pop off clean.
Surprising fact: copper gets hot from friction. If you go too fast, you could burn your fingers. So slow down, champ. This isn’t a race to the ER.
