If anyone can help me out with this I'd be very grateful, I've been trying real hard but am making
no progress whatsoever.
A little while ago I damaged a (newish and machine built) rear wheel. A pannier bag became jammed in
it and slightly bent a couple of spokes, loosening a few others and sending wheel out of true.
Thought this would be a good opportunity to begin learning to repair and eventually build my own
wheels. My attempts so far however, whilst initially seeming promising, are failing as soon as I
ride the bike.
Been getting plenty of advice and tips in uk.rec.cycling but am still failing dismally so thought
I'd summarise efforts so far and crosspost to rec.bicycles.tech in the hope of further help.
I've now trued the wheel 4 times and am pleased with the "workshop" result, but as soon as I ride
the bike the wheel practically disassembles itself within about 10 miles!
As I've practiced (and received helpful advice) I've become more confident in actually working on
the wheel and have been focusing on the following:
Spoke tension, I'm now able to gradually increase tension as I true the wheel to the point where
I can't go any further without rounding the nipples. *Lots* of tension driveside, slightly less
non drive.
Spoke wind up, been working hard to avoid it. I've oiled the nipples and am religiously over winding
spokes and then turning back slightly to release wind up as I tension and true the wheel.I'm getting
better at actually recognising/feeling it as windup releases.
Stress relieving, initially I was probably too timid with this but have been very positive last
couple of attempts. Am using the lever type method described on Sheldons site.
Getting *even* tension around the wheel. Not sure I did a good job of this first couple of times.
Found it a bit hard to gauge with novice fingers. My fourth attempt (finished about an hour ago, not
been out on it yet) I loosened every single spoke in the wheel so I would have a known starting
point to work from. Began tensioning and trueing from threads *just* inside nipples on each spoke.
I've been following the instructions on Sheldons site (thanks to him for great website) and also on
other wheel building pages I can find (Park Tools for example). I'm being as thorough as I can, I
seem to have a fair understanding of the mechanics of the job and the repairs seemingly go well.
However, on riding the bike, within about ten miles several spokes work completely loose, a few so
badly that they are virtually free of the nipples - no tension at all left. Other spokes are not as
bad but still much looser than when I finished the job and others have retained all of their
tension. Obviously the wheel is way out of true at this point. This is the same pattern each time. I
have absolutely no idea what I'm doing wrong or what else to try (if this latest attempt fails).
What am I missing? Stupid mistakes to beware of? Steps not followed correctly?
If anyone has any insights or advice that may help me please post, I really want to make some
progress on this.
(My original plea for help and the following thread in uk.rec.cycling is available here:

Thanks for reading if you made it this far and thanks in advance if you can help.
PS. The front wheel of this pair is doing just fine, no problems with it at all.
