Just to clarify, I said 1/8 in an offhanded way but what I really meant was something more like 1/16. As alluded to above, I am starting to lean toward the idea of a very slightly preloaded bearing idea. Also, to advise someone who is working to refine their understanding/technique instead to visit a professional is ridiculous, not to mention antithetical to using this forum.

1/16 of a turn is still 22 degrees of turn, which is a crude coarse adjustment on a headset. This means you are not even beginning to get good adjustment. You're working like a truck mechanic. Try reading the link I gave you previously. It's from Tom Kellogg, whose reputation and experience as a mechanic are pretty well known. And he's a fair writer. When it seems that someone posting here is just not getting the drift and is set on doing things that will damage their bike, and take them in directions they don't want to go, yes, I will recommend using a professional. Antithetical? Sometimes it does seem like the idea here is everyone should learn by destroying fleets of bikes. Preload simply does not work on headsets. If you think it does you have not worked on headsets and are missing the point. Work on a few thousand headsets for a few decades and then inform us of your wisdom regarding preload or other subjects.

Or do it your way and get a bigger hammer.
