I need some wheel building advice please.
I have built lots of wheels and never encountered this problem before.
New rim (TT 32hole), new spokes (180mm non drive side, 177mm drive side), New hub (TT SL M30), Old nipples (Red).
3 cross pattern used
Each nipple has been turned 9 full rotations. (18 half turns)
And I come across this problem where some spokes are tight and others are loose. Some are so tight, I don't want to continue turning these, the loose ones will reach tension eventually, but the spoke head is quire exposed.
I then noticed that the pattern is cyclic.
All the spokes that are closer to the wheel centre for the first two crosses are tight
All the spokes that are further to the wheel centre for the first two crosses are loose.
The only thing I can think is that the spokes a not cut to the correct lengths, annoyingly, I didn't check this pre build and I really don't want to have to delace the wheel to measure them unnecessarily. However the spokes that were left over (x2 of Each) look correct.
The other thing I was thinking is that perhaps this hub has a weird hole offset, but I doubt this would account for millimeters of difference at the nipple.
I initially only bought the hub (TT) and spokes as I had a spare TT rim, found this problem, blamed the rim as it was bent already without any spokes. Bought a new rim and have the same problem.
