Ash-Kennard Posted May 25, 2016 Report Share Posted May 25, 2016 (edited) Hello All, 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. Help Please! Cheers, Ash Edited May 25, 2016 by Ash-Kennard Quote Link to comment Share on other sites More sharing options...
ooo Posted May 25, 2016 Report Share Posted May 25, 2016 Yeah I'm pretty sure you have just turned the hub the wrong way for the spoke direction, the holes are offset slightly. you need to spin the hub the other way to lace it, if that makes sense. i've done it loads of times lol.

ooo Posted May 25, 2016 Report Share Posted May 25, 2016 that diagram is lush by the way. Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted May 25, 2016 Author Report Share Posted May 25, 2016 Thanks, I like to be clear... What exactly have I done wrong? What is the fix? Quote Link to comment Share on other sites More sharing options...
Ali C Posted May 25, 2016 Report Share Posted May 25, 2016 you've got the wrong hole The yellow is where you've got it but the green is where it should be I think that's right anyay, I find it hard to mentally build a wheel rather than having a physical thing, definitely not a spoke length issue, it happens to the best of us at times.

Ash-Kennard Posted May 25, 2016 Author Report Share Posted May 25, 2016 Ahh thank you! I also like the diagram. I'll try that now. Quote Link to comment Share on other sites More sharing options...

I've done it a couple times, when I do it means that every two spokes on the rim are loose/stick out, next two are tight, next two stick out etc... Fairly easy fix though.

forteh Posted May 26, 2016 Report Share Posted May 26, 2016 Agree with what ali says, when lacing a wheel I only lace up one direction on one side at first, then fully rotate the hub to pull the spoke tension up and then lace up the opposite direction on the opposite side. All things being right you should have the wheel with all spokes at even tension and the hub centralised (nominally) on the rim. If that makes any sense Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted May 26, 2016 Author Report Share Posted May 26, 2016 Cheers guys, all sorted now 2 Quote Link to comment Share on other sites More sharing options...
