My first wheelset build here. I am following Sheldon and this guy. They both stress very much to tighten the nipples to an equal length, for example just as the spoke threads stop showing, and the even more carefully, do equal number of turns on each nipple, in small increments.
Building the front wheel I followed this advice and the result was several very tight spokes and a wheel out of true. My next step was basically to make the tension on all spokes equal, and then true the wheel.
The wheel is true now and looks ready for use (dishing error, vertical and horizontal mis-alignment are small).
So why equal number of turns, if in the end equal tension is the desired result? Or did I do something wrong?
On another note, the rim freshly-purchased, should be true (looks true, and carrying the two rims next to each other, there were no gaps between them, meaning at least sideways being true). So it makes sense to tighten the spokes with equal tension, to avoid twisting the rim, right?
PS: I triple checked that the nipples are well seated into the eyelets and that the lacing pattern is equal everywhere and the same as on an another wheel.
