tu58 - reading off end of reel?

Speaking of which.... I have two TU58 drives, both have a bad set of rollers. One is built into the 11/44 cabinet, one is a standalone desktop version. I decided to follow the "tygon tubing solution", but haven't actually done it yet. I have two questions: 1) What is the best way to cut the tubing to get nice clean round edges? I tried to make a slice, but the tube gets bent/flattened due to the pressing down of the blade so the resulting cut is "oval". Some kind of hot wire/knife maybe? Gently sawing would leave jagged edges... ideas? 2) The old gummy roller comes off, but there is still some gunk left on the metal capstan center. I could put the tube over this, but it may slip a bit perhaps. Is there a good way to get the final remaining goo off the capstan? I'm afraid to scrub it or anything for fear of damaging the tachometer hub. Oh, and also, anyone have a good source for blank media for the TU58? Thanks!
