How easy is it to build your own wheels?

[minor_LEGEND]

With the right length spokes (correct) & a wheel to copy it's pretty easy.
Strip down & rebuild an existing wheel is how I learnt, at least you know it will go back together correctly. Just note where the valve hole sits in between a pair of spokes - that's a typical rookie mistake. Get a decent spoke key & maybe a nipple driver to speed you along.

I asked because jumping straight in with your dream wheelset might not be the best idea. As Eric has said, learning on a cheap wheel first is what most people do. Maybe build the bike with whichever wheels you have to hand and then build the dream wheels after you have had some practice wheelbuilding

Will give it a go on an old wheel. I have plenty of them lying around! Thanks for the advice, links etc.
