i'm embarking upon a first time wheel building project. i've measured all my parts to calculate my needed spoke length, and came up with front(L/R): 296.4mm, rear(L): 296.5mm, rear(R): 294.8mm
i'm just curious how much play is in the calculated spoke length? are the lengths determined so they end up with the end of the spoke in the middle of the nipple, or closer to the outside end of the nipple?
my curiosity is driven by wanting to just get a box of spokes at the same length since they seem really close to me (but then again, this is my first time). can i get away with using 296mm spokes for all? or will the 1/2mm short on the fronts and on the rear-lefts make them too short? will i have to grind down the extra on all the rear right ones?
thanks for any help.
