I was using spocalc but its given me some odd measurements.
ERD, effective rim diameter 561.4
OSB, offset spoke bed 0.0
WL, width from center to left flange 33.7
WR, width from center to right flange 19.8
dL, left flange diameter 58.3
dR, right flange diameter 58.3
So it gave me:
3cross 302.5 301.3.
Turns out its closer to 260 so what went wrong?!
Can send the file if needs be as im sure its a rookie error yet its worked perfectly the previous tomes i have used it.
