So I just put together a new wheel: 1x, undished. all elbows out, alternating "lacing" under/over for trailing/leading spoke.
As a starting point all spokes are adjusted with one or two threads showing. However, the funny thing is that some are completely slack while others are very tight. Specifically all the trailing spokes on the drive side and all the leading spokes on the NDS are slack (all others are tight). This forms a pattern at the rim where every other pair of spokes is slack (slack, slack, tight tight, slack, slack, etc). There are no other apparent patterns or rhyme to the slackness (for example, no consistency with under/over "lacing").
I don't want to waste my time finishing the wheel if something is wrong. What gives?
