Got an old 2" cast iron drain pipe that has cracked lengthwise about 2'. I've temporary repaired it with plumber's epoxy but I will eventually have to cut out the section and replace with PVC. I tried cutting it with my reciprocating saw today but it just shined up the surface. What's the best way to cut it? It's in the basement and up near the ceiling so I can't get a full turn on a pipe cutter. I'm also a little concerned about about crushing the pipe with a cutter. I need to leave stubs intact on either end so I can use rubber fittings to join the PVC to the cast. There's only about 5" of uncracked pipe at one end. Ideas?
