I used the DT Spoke Calculator to determine spoke length for a front wheel build on a Deore disk hub. I used the archived values for the Deore hub from DT's website, which, I realize now, must be for the non-disk version. I spaced, at the time, on the fact that a front disk wheel is not going to be zero dish and will not used the same sized spokes for each side.
So now I have a built up and half tensioned wheel with most of the left (disk mount) side spokes poking through both walls of the rim.
Do I have to totally take apart the wheel and rebuild with spokes 2-4mm shorter for the disk side or is there any way to safely lop off the protruding ends and save myself a bunch of work? Oh well, if I have to re-do it I guess I just get some more practice.
