• Hope you get it sorted mate, i started building my own wheels not too long ago and with a bit of patience its no biggie.

    As for this statement;

    "the Edd calculator above says "ERD is Mavic's Nipple Seat Dia + 3mm for nipples"

    be wary as i had a smilar statement pop up on the spoke calc when i built some rigida DP18's and bought 280mm spokes (as the spoke calc told me to) and found they were too long and ended up using 278mm's instead. I think this statement means you should subtract the 3mm off the answer? It should/could/would be nice if it was incorporated into the final equation but it obviously wasn't when i used it.

    If anyone could give a definitive answer on this i'd appreciate it - i've built several wheels since and not had any problems with the calculated spoke length but all these more recent wheels have not had the statement above attached to the rim info.

    I noticed your in Peckham - i live in Canada water and have 3 wheels to build up this weekend if you want to sit in for a bit to see whats involved?
