Knurling?  Ugh.... let me count the ways I've done it wrong:

- the knurling tool isn't square to the work
- the OD of the work isn't a multiple of the pitch of the knurling wheels and never settles down into a pattern.
- on those cheap-ass 6-wheel/3 pair bump knurl, the axles are undersize, the wheels wobble, and your knurls look like poop.
- on a pinch knurl, you install one wheel of one pitch on the top, get interrupted by a phone call, and install a different pitch on the bottom.  You get an interesting rectangular pattern with that.
- you squeeze the knurl too hard and you get flakes of material coming off the work and the knurls look shaggy.

Here's a neat video on making your own knurl wheels from ClickSpring.
