I have cut rolls before with a bandsaw. I taped around the end of the roll several times to create a shield. After cutting, I sanded the end on a 12" stationary disc sander to get a smooth surface. Had to air gun off everything when finished. The only tricky thing is that the roll wants to "roll" during the cut - best to cut a wedge to keep it from turning. Also, it's a good idea to keep it in a plastic bag during cutting - eliminating some of the mess. If you don't have a bandsaw and a stationary sander, find a local woodworker in your area. Look up a local chapter of the AAW (American Association of Woodturners). There's a lot of those guys out there and most of them have bandsaws and know how to cut round tubular objects on their bandsaws (they cut a lot of limbs and logs that way), and most of them have stationary disc sanders too. They're a very friendly bunch - would likely not charge much if at all. This method works well - I've done it many times.
