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 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. |

My lessons: do the lacing first (obviously), get the radial (which you call vertical) correct as possible next, and then Hm, I did try getting the vertical/radical first and it makes it a bit easier and the wheel is now a bit rounder. Trying to get the radial right after lateral and dishing sounds like a nightmare. You are not wrong there. If it's not a new rim, it may have issues. I think I have issues PS: Four hours?

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 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? |

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 BTW, what tension release do people use whilst building?
