I'd like to try my first crack at wheel building. I'm ok with the lacing, truing, dishing, etc, but the spoke length calculation is sort of concerning me.
I've gone over several sites showing how to measure the hub to get the various dimenions required for the spoke length formula, and I'm sure once I pick up a cheap caliper, I could probably pull it off.
The thing is.. I want to build this wheel with some heavy duty DT Swiss Alpine III spokes, and if I get the measurement wrong I could end up wasting a chunk of change on the spokes.
I have the factory measurements for the rim's ERD (Sun Rim Rhyno Lite), but unfortunately I can't seem to find the measurements for the hub.
It's a Shimano FH-M475 (pulled off of the stock rear wheel of the 2007 KHS Alite 3000).
Both the rim and hub are just spare parts I have kicking around.
I'm not sure if any of you pro mechs have access to any info that's not available to the public.. if anyone could tell me the proper measurements for this hub to calculate spoke length, I'd appreciate it.
