I tried it once, didn't like it. With the availability of spare tubes already cut to length, I just keep some extra on hand for the kits I routinely make. When I did cut them, I used my chop saw, I know not the best way to do it, but it got the job done. Also with buying them already cut, you don't have to worry about getting the lenght just right. I do know that PSI sells tubes in certain diameters that you can cut yourself.
