Just learned the
GOLDEN RULE of wheelbuilding ..... again.
NEVER trust the dimensions supplied by others
The dimensions given from the Hunt website were as follows with (actual in brackets)
NDS Flange dia - 43mm (53mm)
DS Flange dia - 34 (44mm)
NDS Flange Dist - 33.75mm (34.5mm)
DS Flange Dist - 17.55mm (16.45mm)
Spoke length - Rear NDS - 292mm (287mm)
Spoke length - Rear DS - 290mm (284mm)
Plumbing the measured numbers in the DT Swiss calc yields calculated spoke lengths of 287.6 for NDS, and 285.2 for DS, so have some faith in my measurements of the hub, but will double check again over the weekend.
So they were close .....
