Chip, I have cut up to 12 inch pipe a couple of different ways. The most
important thing is to carefully and accurately mark a line all the way
around the pipe. The best way is if you happen to have a plastic collar
that fits the pipe, but we never have one of those :( I use a tape measure
and put a series of dots around the pipe. Next, I take a flexible plastic
ruler that actually wraps around the curve of the pipe and I connect the
dots with a marker pen. I ususally drill a 1/4 inch starter hole then use a
reciprocating sabre saw to cut along the line. The second faster way is to
use a circular saw with carbide teeth (use a blade designed for fine cuts).
It helps to have someone help turn the pipe as you saw. Watch out for
fingers! I have had excellent results making cuts both ways. You can take
very course sandpaper or emery cloth and staple it to a piece of plywood on
the floor. Stand your pipe on the sandpaper and rotate the pipe; you can
make the end of the pipe extremely flat if you are a perfectionist.
