Sometimes, even a mini cutter is too fat for the gap. You look at the space, and it’s narrower than a politician’s promise. In that case, you bring out the hacksaw blade—just the blade, no frame, because the frame is a useless piece of metal art in this situation.
Wrap one end of the blade in duct tape to make a handle, or just grip it with a towel if you’re feeling brave. Taking a hacksaw blade to a copper pipe is slow, messy, and humbling. You’ll make a dozen tiny strokes, each one feeling like you’re fighting a tiny, angry sawmill.
Be prepared to create a snowstorm of copper dust that will get into your nose, your hair, and your soul. But hey, it gets the job done, and you’ll emerge looking like a deranged elf who’s been mining for gold.
The Deburring Drama (Don’t Skip It!)
Congratulations, you’ve cut the pipe! Now, do not skip the deburring step. That sharp, jagged edge is waiting to slice your O-ring, your fitting, or your finger when you least expect it. Use the deburring tool on your cutter, or a simple file, to smooth the inside and outside of the pipe.
