You and Eddy Merckx.
Bet it takes a while to build a wheel.
Hope your roads are good. Around here, you'd need a chiropractor by the time you rode thirty miles.
I was in the business from the mid-70's until the early 90's, and wheel building was my specialty. Probably did 200 pairs a year at the peak, so I could lace, tension and true in 15 minutes. I cut and threaded my own spokes with one of the Phil Wood machines, buying blank DT's in the 312mm length. Tying and soldering did take time though.
