yes- use a file, not sandpaper. MUCH more better.MR_GRUMPY said:After the cut, it might be wise to bevel the end a little, with a file.
This won't work very well. I had an old junk seatpost laying around that I was messing with one day and decided to cut off the scarred up end so that I could use the good tube for some project. I used a tube cutter to score the aluminum then decided to cut it through. First of all, it would have been a lot less work using a hacksaw to cut it. Second, the tube cutter works by displacing the material, basically pushing it aside. When the roller wheels on the other side roll over the displaced aluminum, it flattens it. What happens is that you will end up with a raised but of aluminum at the cut that you will need to grind down with a file or something. Not only that but when the tube finally breaks it leaves a really jagged edge on both sides that requires a lot of attention with a file in order to prevent you cutting your hands open on them. Use a hacksaw instead.DieselDan said:Use a tube cutter.

I'd guess that you could treat it like an aluminum/steel fork steerer and use one of these fancy things if you were truly picky.
