there is no complete data base of hub and rim dimensions, but i have found that
damon rinard.com is a fairly comprehensive and accurate source.
wheel building is rad!
good luck!
I agree with you that often the pinging is exactly what you describe, and I concur with your solution (I find a nipple-driver to be the ideal tool), however in my case the pinging was the spokes hitting the derailleur cage, proven by tweaking the adjustment on the RD. Yes, the Damon Rinard information is very good; I have an Excel spreadsheet file which came from that site, it has lots of rim and hub data, and a great spoke-length calculator; a very useful source indeed!
