A while back I posted about being stuck on truing an aluminum A rim on an F rear hub. The spokes had gotten way too tight and I was chasing my tail trying to get it right. (didn't find that post)
Anyway, as suggested by you guys, I walked away for a while. This week I returned to the project, removed each spoke one at a time and put anti seize on the threads and washer. I got the wobble close, then the hop and re-checked the wobble. Last I checked for any spokes not tight enough.
It went well and was worth the effort. As always, thanks for the good advise.
