I built my first wheel from scratch last night
Nothing fancy - a cheap on-one 135mm fixed-fixed hub (reduced to a tenner in their sale!), DT-Swiss DB spokes onto a used but hardly worn Alex ACE-19 rim from my pile of "that'll come in useful one day" bits.
Also trued/retensioned the twisted wheels i built on the fixie as it was getting a bit noisy. I thought it might as the twisted spokes settles down. They don't tell you that in any of the how too guides.
I bult using the Roger Musdson e-book. It tells you how to check for this as the wheel tightens ("flags" of tape on the spokes), and that one of the stress relieving methods (pushing the rim) can sort it out.
We'll see how well I did on the build once I've put it on a bike and ridden it for a bit - which involves stripping all the gear stuff off first.
