Yeah, you can actually cut through the lines really well with a dremel. Sounds like taking a boy to do a man's job, which it is to and extent, but it cuts like nothing is there. The bad part is the little discs are fragile. And of course there is dust. But that is where the snips are good, they cut without any of those problems, though I have no idea what they would be like on some of the upper end tubes, works great on 4130.

Oh yeah, at one point I was looking for some info on grinder wheel explosions, the big vitrious wheels, for a safety demo. By the way, you can grind tubing out on those also. Anyway, despite all the nagging about how unsafe those wheels can be I didn't find much in the way of information, though I did find some accidental death stats. What I did find was photos of the most gruesome imaginable accidents with cut-off wheels. Heavens! If you are into that kind of thing, what a rich resource.
