    Although it's been many years since I was trained in cast iron, I was taught to break the pipe down to the flange with a crescent wrench.

In discussions with older plumbers, I was sometimes asked if I cut my cast iron pipe with a hammer and chisel, but no, the companies I worked for could afford a cast iron snapper.

    I still use a crescent wrench to trim a piece of cast that didn't cut cleanly. Am I the only one?
    no you're not but there is always a chance that the stress of using a crescent wrench will cause a crack down the bend. in a slab no problem. above ground, good chance of a leak.

    the internal cutter is more of a rolling tubing cutter than a snap cutter. it cuts a grove into the pipe more than just snapping it like a snap cutter. sort of the way we snap old cast with a rolling motion instead of a snap

    a die grinder/ (dremel on steroids) does a much better job from the inside of the bend, than a grinder on the outside. plus most of the dust and fines go into the pipe and not the surrounding area to rust up. you don't need to completely cut through it, just score it 25% or more. then a crescent wrench is safe.

      The crescent wrench trick works when the piece is large.
      Try rotating the snap cutter back and forth as you tighten it, works a small groove into the CI and makes the final cut straight.

        Above post obviously not relative to internal pipe cutting, the most common reason I get ragged cuts is with snap cutters...when I don't rotate it.

          "Something magnetic happened."

          The magnetic bit holder of the screwgun imparted a magnetic imprint on the screw head when it was driven into the rock causing it to become slightly magnetic. Just enough that it can attract fine ferrous particles like your trailings from cutting CI with a grinder.

            Looks like a sure fire way of locating the studs

              LOL, thanks for clearing that up for me, I could tell where every stud was located, great for the customer, she could hang pictures successfully.

              The crescent wrench trick works wonderful by the way

                  we are talking cast iron/ no hub.

                  plastic is a no brainer to cut to the proper height.

                  we don't use a 3'' closet bend out here. we use a 4x3 closet bend and 4'' closet ring.

                  why not just stub your 3'' riser high and cut to the finished height?

                    Off-topic but very interesting method for ABS. Like Rick posted it would be easier just to cut your riser when you set your flange but what do you do about your test plug?

                      I leave a 3" stub dryfitted with a dollar plug in the hub under the stub when not sure of the finish height.
                      100% guarantee the tile guy will go as close as possible...hammer drill for flange screws.
                      When I know the height, I use 1/2" strapping under the flange on the sub-floor.
