I'm working on building my second set of road bike wheels. Tonight I trued up the rear wheel (36-spoke cross-3 lacing) and got it stress-relieved and trued both radiallly and axially to within less than a half a millimeter, and dished to within about a half- millimeter.

In addition, the spoke tension (by sound) is remarkably consistent, with no spokes significantly tighter or loosed than the rest.

My concern is that I got it to this state relatively quickly, and the spoke tension might be a little low. The wheel is so darned true at this point that I'm afraid if I try to put some more tension on the spokes that I'll lose what I've gained.

The book I'm following (Professional Wheel Building by Roger Musson) and the wheel building class I took last year both were much more concerned about OVER tensioning spokes, so I'm not sure what I'm risking if the spoked are UNDER tensioned.
