New here, just bought a house last year and have been doing repairs ever since, and its great.
Problem: I want to cut a 1 1/4" galvanized steel pipe used for steam heating. The reason is because I need to move a radiator. Normally, I would use a sawzall with a metal cutting blade, but I need cut the pipe square in order to thread it and attach an extension. The pipe is running parallel to the floor joists and is quite close the bottom of the first floor. I don't have enough room to use a pipe cutter.
Question: How should I cut the pipe and keep the cut square enough to thread the galvanized steel pipe?
