I use a brobo coldsaw
http://www.brobo.com.au/coldsaws02.html at work which cuts tube perfectly and clean, so if you had to do it again just yell out to your local small metal supplier who will probably do it for $5 if not free lol. God do i need a lathe to, but money holds me back
Good work with the drem, lol i hate using the things for cutting because of disc breaking and flying miles.
