Hi all. I use a Park TS2 and have the centering tool which helps. But i occasinally have problems w/ drift and so i routinely use a dishing tool as well. I don't have the best eyes and i'm tone deaf so i use a tensionometer to make sure i'm in the ballpark. The main thing that's changed since i started is that i tension the spokes considerably more these days. I'm not a great wheelbuilder but i can turn out a decent wheel because i'm persistent - anal - even. My 2 best teachers are Jobst Brandt's The Bicycle Wheel and Gerd Schraner's The Art of Wheelbuilding w/ a slight preference for Gerd's. Like many skills wheelbuilding improves over time ,but, as was noted, even a beginner can turn out a better wheel than what's available "off the rack." Gretings to all the lovers of vintage bikes.
