viva la v-brakes!
So I'm lacing up a new wheel and for some reason most (but not all) of the nipples won't thread in all the way. I back them off and scrub off the spoke prep, thinking that maybe I put too much on and its clogging up the threads. Still no dice. Eventually I realized that most (but not all) of the nipples the shop gave me are for 15 gauge spokes, instead of the 14 gauge spokes I'm using. I pulled just enough new nipples out of my parts bin and I'm back in business. But now I have removed most of the spoke prep from the spoke threads. Do I have to unthread the wheel and re-apply spoke prep? Or is there a shortcut way to do this, maybe dip the tip of the new nipples in spoke prep as I install each one?
