How to get a straight cut on 2" ID copper pipe?

[toolguy603]

I'm working on changing over some old 2" ID copper pipes, which are leaking, to PVC. I have the correct PVC to Copper Fernco Proflex adapter, but I need to get a nice straight cut of the copper pipe to insert it into it. The space is tight, so I'm having trouble finding a good tool to use to do this.

Earlier today, I was practicing cutting 2" copper pipes with a power multi-tool (with the correct blade to cut metal) and I was having trouble getting a straight cut.

I hope someone here can help me out with some tips or techniques to get this done.

I would use some strong limp string, like fishing line, tight around the pipe. Then use a fine-tip Sharpie to draw a line left and right of the string.
EDIT: the paper is better if you have the room.

A sheet of paper or the like is better, as the edge of the paper is kept straight by the paper itself (if you avoid folds). With string, you need to pull really tight and possibly wiggle the string at various points around the perimeter while pulling tight to ensure you actually find the shortest possible route around the cylinder (which will be the desired circle in a transverse plane).

Thank you all for the helpful responses.

I ended up using a thicker piece of paper to draw a line around the copper pipe with a sharpie. I then used a Husky 2-1/8 in. Quick-Release Tube Cutter to cut around a portion of the copper pipe. Since it's a tight space, I was only able to cut some of the pipe as I could not move the tool completely around the pipe. Then after I had some of the pipe cut, I used a small hand hack saw to finish the job. Now it's a nice straight cut.

Thanks a bunch everyone!
