I have a 3’ long, 3" diameter copper pipe that is 14gauge. I secured
it in my vice with a piece of wood inside surrounded by a towel to
help keep it from collapsing (although it would take quite a bit of
force to collapse this). The pipe was part of a steam pipe used in
an electric plant that was replaced.
I used a punch to create a few holes and tried with my hack saw to
saw through this. It scratched the surface literally but didn’t make
any progress. Without having to buy a special cutter for $150 to use
one or two times, is there something else I can use, maybe a special
blade for my circular saw, machine shop?
Wondering if anyone else has found an answer for cutting large
