The rim I'm using is a
36h 700c Velocity Deep V (ERD is 882). I found this pretty keen spoke length calculator on Mr. Brown's website:
http://www.sheldonbrown.com/rinard/spocalc.htm
It's an Excel spreadsheet works well with the info on the hub that I got and the info on the rim. It have me all the spoke lengths I need: (0) 260.9; (1) 263.5; (2) 270.8; (3)281.3; (4) 293.2; (5) 293.2 (just in case they don't have the right length for the three cross.)
This is the spoke length calculator that I use:
You can change the variables. The only requirement is that your computer (most do) have JAVA installed on it ... if not, you can download it from SUN MICROSYSTEM's website.

However these lengths are calculated on the information found for that particular front hub (
http://www.yogarup.com/wheels/hubs ) (the first one on the top of the list.). I'm not sure if it's this one:

It's off a previous bike I had, a 2006 Bianchi San Jose.
Well, you are going to be very unhappy if you use the ARUP data because those are for
high flange hubs (most track hubs are high flange because the resulting wheel will generally be
laterally stiffer) -- your "Bianchi" hub is a
low flange hub.
You can use the data from almost any low flange hub ... the flange diameter will probably be either
38mm or 39mm, or something in between. The calculated difference in the spoke length is negligible ... when in doubt, round DOWN.
Here's the calculated spoke length data (
presuming an effective rim diameter of 582mm for your Velocity Deep V rim):
283.0mm == 32x3
285.3mm == 36x3
AFTER you decide WHICH spoke holes in the rim you want to skip (none, personally) & I recommend that you lace up hub with either
284mm (or, 285mm) spokes with the presumption that you will need to shorten several of the spokes ... BUT, I have a spoke threader & can shorten & the length of a too-long spoke & add threads as necessary ...
The shorter spokes will probably be ~3mm shorter than the longest spokes, BTW.
