I'm just working on my first wheel build, and it appears that I completely messed up the spoke calculator when I ordered the parts. It looks like be the time I tension everything up, the spokes will be sticking several mm past their nipples on the inside.

Now, it's a double walled rim, so everything is recessed...I'm thinking that once I put in the rim tape, nothing will be in contact with these overlong spokes. Is this a reasonable assumption? Can I keep building the wheel, or should I pull all the spokes out and order shorter ones?

I don't really want to take it apart, but it's for my winter bike, so I've lost of time to get it finished if I really have to.
