So I've dipped my hands into the cool waters of wheelbuilding and to this point, so far so good. By so far, I mean 3x and no dishing, which suits my needs fine, but, I decided recently to spoil myself and build a new front wheel. I thought, hell, radial can't be any harder than 3x can it? I'm very wrong.
3 times now I've built and rebuilt the wheel, each time the wheel isn't round. I've threaded all the nipples to the same spot, tightened them all the same amount then done the trueing, and still, no dice. There's always a skip to it. And now this most recent rebuild I fear I may have over-tightened some of the spokes in order to compensate.
So I'm all out of options, I feel as if I've followed the most appropriate technique to building a wheel, but at the same time, it never really comes out round. I had all the spokes cut and milled at a LBS, and as much as I trust them I somewhat have the impression they may have been slightly different lengths. Would this effect the outcome?
Finally, after the last reconstruction of this hellish circle I've noticed some stress marks on the rim itself. They aren't cracks or other such physically noticeable blemishes, but rather under certain light areas by where the nipple extends through the rim the light reflects differently, as if the metal has been slightly stretched.
Oh, and it's a Velocity AeroHead rim (700c) laced with cut and milled single butted spokes to a Miche Primato high flange hub. Any suggestions as to what's best to do in this situation would be greatly appreciated, as for I am wholly stumped.
