I just built 8 wheels last week and have built about 6 dozen by now. I was taught by a pro wheel builder but, I have the memory of a dog a times so I often refer to this when my brain starts skipping. Tensiometer is pretty clutch until your skills get good enough to do by feel. When I build for someone else I do it by the book to tension and double check uniformity, I don't want any complaints or problems later on. Lack of tension can cause big issues down the line.

Check this guy out ... good wheel resource
