I bought a computer monitor stand which is essentially a stainless steel pipe mounted vertically (clamped to the desk) with a metal fitting which is mounted on this pipe and slides up and down, on which you attach your monitors. The metal mount doesn't touch the pipe directly, inside is a simple plastic collar which allows you to tighten things up with a screw - the screw pushes the collar up against the pipe.
Anyway, at one end of the pipe the bracket moves very easily, but at the other it is rather tight. I have loosened the screw-tightening thing fully I am guessing the pipe is just a fraction thicker or has minuscule bend at one end, nothing is visible to the naked eye and running my hand along it detects no difference in feel.
Is it feasible to simply sand the pipe? I have no idea how much I need to wear off, if it's something a quick sand would achieve or if that would take hours. Also, is roughening the pipe by sanding going to make things worse?
Perhaps sanding the inside of the plastic fitting would be better, but since the tightness varies along the metal pipe it seems the pipe is to blame to me.
