Ok, I think I've got it. Can someone check out my math and make sure it's ok?

The Hub's specs are:
OLN 135 mm
Spoke Hole Diameter 2.9 mm
Left Flange Diameter 93 mm
Right Flange Diameter 93 mm
Left Flange Offset 29.5 mm
Right Flange Offset 24 mm
Weight 1600 g

A diagram of its measurements can be found here: http://www.kstoerz.com/freespoke/img...f=29.5&rctf=24

The rim's ERD is 599

So on the socalc calculator, I entered:

N, total number of spokes: 32
ERD, effective rim diameter: 599
OSB, offset spoke bed: 0 (******************************?)
WL, width from center to left flange: 29.5
WR, width from center to right flange: 24
dL, left flange diameter: 99
dR, right flange diameter: 99
S, spoke hole diameter: 2.9
X, cross number (decimal allowed)(optional): 3

For 3-cross, this gives me:
Left: 284.3
Right: 283.8

Does this make sense? Did I enter everything correctly? And what the heck is an OSB?
