Default Truing a wheel

Apologies for bitching about this again, but you know what it is like -
you know it should work but it doesn't

I have had a problem truing my rear wheel and so I saved up some money
and got myself a truing stand and a dishing tool. Having these tools
will make me an expert wheelbuilder - or so I thought.

I have also "carefully" read Sheldon Brown's tutorial on wheelbuilding
(http://www.sheldonbrown.com/wheelbuild.html), so I am now ready for
ANYTHING.

Having produced wonderful almost egg-shaped wobbly wheels in my previous
attempts by eye, I was certain that my new efforts with my new toys,
eeerrrr.. tools, would give me a precisely round and perfectly straight
wheel.

Now, 4hrs later, I have given up, loosen all my carefully tightened
spokes and my wheel is now ****ed!! DO YOU HEAR ME?? IT IS ****ED!!! HOW
IN THE HELL AM I GONNA GET AROUND TOMORROW, EH??

Sorry for that outburst - it was good to get it off my chest. I know I
just have to start all over again - that's all.

I am no closer to that elusive round and straight wheel

Lateral trueing and eliminating dishing are relatively easy to achieve,
even without the trueing stand and dish tool, but I suspect there must
be some tricks in getting vertical truing but I'll be damned if I knew
what they were.

I am gonna re-read Sheldon Brown's instructions on getting rid of high
spots in lateral trueing, having something to eat, have another beer and
try again.

I have limited experience - ie, have seen it done a couple of times, and
I have backed off and trued a (rear) wheel that was not good but the rim
was not majorly off. My lessons: do the lacing first (obviously), get the
radial (which you call vertical) correct as possible next, and then
dishing+lateral (and minor issues) last - small adjustments and re-checking
the radial pretty often. For lateral, do large sections at a time (could be
8 spokes per side) first before attempting smaller (eg back off 2 spokes
on one side by 1/2 or 1/4 turn, tightening three on the other, recheck
everything and look for the next...

Trying to get the radial right after lateral and dishing sounds like a nightmare.

If it's not a new rim, it may have issues.

T.

PS: Four hours? I probably spent close to that time. Wheel builder was more
like 20 minutes.

It takes a lot of practice. I'm pretty crap at getting the radial
(vertical) aspect right, I usually end up considering getting within 1mm
as being adequate. :-)

Hm, I did try getting the vertical/radical first and it makes it a bit
easier and the wheel is now a bit rounder.

You are not wrong there.

I think I have issues

20mins!! Man, I wish

1mm is damn good! So far, by starting on the vertical and getting it
sorta right, and moving onto the lateral, and rechecking the vertical
has worked for me (kind of), but I am still nowhere near that 1mm I
think I have a flat bit on my rim.

I have tried to build a wheel and failed. I have tried to change all
the nipples, one at a time, and failed.

I can true a wheel and keep the dish correct.

In my case, my failure is primarily in making the wheel round I have
found that egg-shaped wheels CAN actually go around and around but one
needs to get use to the additional ... eeerrr.. stimulation (?) around
the sphincter region from the seat

I can true a wheel and keep the dish correct.


I am reading that as being lateral trueing, right?

Dishing is easy to fix with the -ahem- professional truing stand I now
possess Awright, awright, it looks like a real professional truing
stand , ok?

New materials, yes.
Old materials very, very hard.

BTW, what tension release do people use whilst building?
I grab bunches of four spokes and squeeze.
It get really tedious when you get down to trning the nipples 1/8 of a turn.

I suspect that is my real problem as I have one area on the wheel which
seems flatter - almost as though that section has been bumped real hard

I grab a coupla of spokes on each side and squeeze.

A pair at a time, and make sure each one gets squeezed left and right...
