This is the easiest, most accurate way I have ever found to roll paper. Ideally, you want the paper rolled so tightly that it must be expanded to achieve the correct diameter. If it is rolled to loosely, the edges may not be truly circular. Of course, if you are using bulkheads, it's a moot point.

Again, using the parts from a printer, or brass tubing as someone else pointed out, wooden dowels...whatever, tape one edge and carefully align it square to the rod. The tape allows you to roll the paper tightly against the rod. Then just roll the rod over the paper. You can roll very small diameters easily and accurately just by using small diameter rod.

I've rolled some parts under 1/8" diameter using regular weight paper. But, I will confess; I wised up. I'm not a purist. Anything that small, I'd rather use rod or wire and paint it!

To keep the tape from being too sticky, afix it to your forehead or cheek first. The natural oils from your skin will decrease the tape's stickiness so that it will not pull ink off the paper and so that it will release easily.
