1966 BMW R69S Restoration: October 1999
1999 October 23 (Saturday)
The restoration effort ground to a near halt the last month. I spent some time playing with the wheels, but not really making any progress.
Borrowed stand
I swapped my home made stand for a borrowed truing stand (actually a wheel balancer) that was a bit more stable. The third picture shows the home made tool I used to get the wheel close to true before breaking out the dial indicator.
Once things were close I checked and adjusted radial and lateral run-out. I was told that once the rim is true the key was to keep it true as the spokes are tightened. This assumes the edges of the rim are parallel to each other. Not true on one of my rims. When runout on one side was within the .008 in spec the other side of the same wheel was out by over a millimeter.
Also, my check for out-of-round was being measured at the wrong place. I should be measuring where the tire bead sits.
