Ok, so I got a new set of wheels that were badly out of true. I took this as an opportunity to really learn about wheel building. I laterally trued, radially trued, rechecked lateral true, then checked dish...and repeated (about 50 times). I didn't have a tension meter so i just kind of guess as to what I thought the spokes tension should be. I've realized that this isn't a good method for a newbie so I got me a park TM.
My question, how far in the truing process do I go while trying to keep spoke tension even? I've heard that in a perfect world with perfect rims/spokes/hubs I'd be able to build a true wheel that has perfect tension. But since the rim/spoke/hubs aren't perfect, in order to get a true wheel my spoke tension will vary a little.
Do you check spoke tension while truing? after truing? or only before truing and then let the rim decide how the spokes should be tightened?
How much deviation between the spokes do you guys allow for? (i.e. one spoke measures 23 on the Park TM, is it ok if the next one is 25?)
Also, is there any place that shows how much difference there is in tension between drive and NDS? How to disc brakes affect DS and NDS tension differences?
