Did this video a couple of years back. My wedge drivers have evolved for sure. The Jonsered 80 STILL runs and gets used from time to time. BUT the section in the second half of this video NEEDS to be reviewed from time to time. I've seen a lot of commentary on this. Usually folks go back to the basics shown here over time. AND these technics have been with me since literally the 1970's when I built my own race bikes. Same show different stage. So if you plan to replace bearings, assemble cases etc. The second half of this video might be a nice "review"
