I built those wheels on rock and roll

Yes, to the sounds of the Pet Shop Boys, the Pixies, Peter Tosh, Pedro the Lion, and some other stuff under "P" on iTunes. Wheel-building is an art. You gotta practice.

Rims: I picked up supplies at Rose Bike Shop in Orono, ME. Some old double wall rims that were on closeout. Jim sold them for 5 bucks a piece! sweet! Best deal yet, considering what I paid for the frame and hub set. Spokes and brass nipples and it was a go. Here's the specs for a cross 3 pattern:

Front Hub
flange diameter 62mm
hub center to hub flange center 33mm
spoke number 32
effective rim diameter (ERD) 610
SPOKE LENGTH: 294

Rear Hub
flange diameter 62mm
hub center to hub flange center 28mm
ERD 601
SPOKE LENGTH: 290

So, I picked up 32 x 1.8mm spokes of each size and the corresponding brass nipples, laced 'em and trued 'em. Ghetto DIY truing "stand" using zip ties on the fork and seat stays was a great start. Heck, it's starting to look like a bike.
