Building wheels...

Just hoping someone has some knowledge with building wheels, have been given some dt swiss 4.2d rims and some Nukeproof Generator hubs (2012), using what I have found on the internet with spoke calculators and so on, I'm not even sure I'm using them right but it's coming up with the following for the spoke sizes, being a complete numtpy when it comes to building wheels, will be getting a mate to do it for me but I'd just like some clarification for myself really whether or not these are right...
Front left 262.5mm
Front rear 261.9mm
Rear left 265.5mm
Rear right 263.2mm
Cheers for any help/suggestions

The Rims have an ERD of 544mm
Have put all the info into several websites now and some are really really off but there are two which are extremely close, wheel pro and spocalc, each are within 0.3mm of each other...

Thanks again, time to order some spokes!
For information, I've built many wheels using the spokecalc and never had a problem yet

I built the wheels on the singlespeed (DT PG Spokes), a couple of ultegra/CXP 33 wheelsets (DT DB Spokes) and a power tap/CXP 33 (DT Aerolite and a 2x/3x mixed) and also rebuilt a couple of mountain bike wheels. Roger Musson's book is worth the money and then some!
If you can't get the spoke length you are after, it's better to go slightly (1-2 mm) longer rather than shorter as building wheels with short spokes can be hard work!
I was assuming 12 mm nipples as it's pretty much the standard length that gets delivered with the spokes. As supersonic says...with 14 mm nipples = spoke length - 1 mm.
