First wheel Build

Finally. This afternoon, I laced a Shimano 6400 UG hub onto an Araya VX 300 rim, using the original spokes(It came with Exage, which needs to be re-built). I used Robert Musson's book as a guide, and the process was straightforward and quite pleasant. It brought back memories of just how much I enjoy truing wheels, a thing I haven't done much of in 30 years. It took quite a bit of tweaking, which leads me to wonder if it will continue to need tweaking. Time will tell. Tonally, the spokes all ring true, and all the same, side to side.
A side question, which I probably know the answer to but will ask anyway. A rounded nipple or two in there. Can I just release tension on those spokes and put a new one on, or do I have to release the whole thing?

Wooo Hooo! Show us pictures. I built my first pair this summer and they're awesome...Shimano 600 hubs and Ambrosio rims. I too, had a few rounded nipples, but they're staying true. I'll cross that bridge when I come to it, though I don't see an risk to just replacing the nipples one at a time like fixing a broken spoke.

In the days of light rims unscrewing a single nipple could cause all sorts of grief. However today's rims are very rigid (and heavier) so it's relatively safe to remove and replace a single nipple or spoke in a new wheel. Obviously you want to do these one at a time, and re-establish a fairly true wheel before doing the next one. Perfect alignment and tension isn't necessary between each replacement.

Here's are tricks that'll both help replace these nipples, and prevent the problem next time.

1- too late now, but next time lace the wheel slightly too far to the right, align and true it and bring it up to something short of final tension. Now dish the wheel to center tightening the left spokes only, which will bring the wheel to final tension while moving the rim to center. The advantage is that you're not working the tightest spokes as much, if at all.

2- buy or scavange a broom handle or a similar 2' piece of wood. When you have to work very tight spokes, use the broom handle against the hub to lever the rim across a bit toward the spoke, and take some load off it.

Thanks, FB.
I did wait too long to dish it, as all the spokes were the same length, so it didn't just dish itself. I went around twice, loosening the non drive side, and that did the trick. I look forward to the next one.

if it was me, and the wheel was true or true enough to start with i would 1) unthread ONE of the stripped nipples all the way and dispose of it. 2) thread on the new nipple and tighten it, and ONLY it, until the wheel was back to it's original true state. 3) repeat until all stripped nipples are replaced.

note: don't worry about the fact that the wheel will be untrue, temporarily, while each nipple is replaced.

good luck and enjoy yourself.

One last hint, I forgot to mention. As the wheel gets tight, switch to a 3 or 4 corner (box) spoke wrench to reduce rounding off nipples, and be sure to push it down and engage the full length of the flats. Box spoke wrenches are slower to use, so stay with the classic open end spoke wrench as long as you can then switch.

I'd love some advice on favorite spoke wrenches --and where to find box spoke wrenches.

Other than one I've had for decades for the old DT nipples, I use Pedros wrenches now. They are slot on one side, box on the other.
Park now also has box types, and there are always Spokeys which lots of folks like. Also even though the keys are sized differently always use the tightest fitting one.


BTW- I have a bunch of new Pedros spoke keys in stock, in the three sizes, Black, red, green, same color code as Park. I can give you a geed deal. Email me using the link on the chain-L site if you're interested.
