Didn't read your follow up after I was done double checking work. From scratch. Started over by re-cutting spokes from method #1 and wound up averaging published numbers for both rims. Spokes ordered..

(I got the 1/8 diameter rod and will prove the work for grins.)

Moving on to finalizing drive train - 52/42 with 13-26 wont get it done for where this will be ridden. The FD has a 14t max ring, RD has 28 max chain wrap and 28t max cog. I want to push both by getting a 13-30 with 48/34. Not worried about the chain wrap as much as getting the 30t to fit. No harm no foul for trying, right.

(This all started out by cleaning the chain. It quickly became a long over-due overhaul. So far there are new/NOS: bars, Brooks, stems and posts, rd/fd, brakes, cranks, hubs and wheels, and a new chain. Most fun you can have with your clothes on!)
