Once that was done (both times in fact), I hit the cut area with some fine sandpaper very lightly just to smooth out the edges. I also added a bead of superglue on the cut surface to keep all the fibers together and prevent fraying. A new fine tooth hacksaw blade makes short work of a carbon tube. My local shop actually has a high quality mechanic that can do this work, but following Rule 58, I prefer to do all my own work. I buy tubes, bar tape, gel packs and such from those guys.
