Wheelbuilding in this case uses "building" to convey the measurement and adjustment required to assemble parts of the wheel. Building from parts, not from scratch materials.
Sheldon Brown was my inspiration for many bike-related endeavours and his website is what drew me to Internet and the WWW in the first place. I used to to into Internet cafés and print out pages from his site – including this very guide. This was what I used for the first few wheels I built. Eventually, I got a copy of The Bicycle Wheel, by Jobst Brandt from my local library.
