Wheel tension
A friend of mine has given me a wheel to retrue. It had a fairly big ripple in it. I'm getting a cake for providing this service, so as you can see, the stakes are high.
Trouble is, I can't get it anywhere near true without wildly differing tensions around the wheel, to the extent that there is a noticeable difference from one pair to another when I squeeze them together . Does this mean I'm working with spokes that have gone into yield? If so, how do I tell which spokes are duff? I fear that if I just true it up as tight as possible, one bash and it'll taco if the tensions are so broadly spread.

I slacken the opposite if I think I am having to apply too much tension, has virtually the same effect as tightening the other side. Just watch the dishing!0

If trying to true a big deflection, I'll wind up the spoke tension to get the rim true and then wind off all the spoke tension - the rim generally stays true - and then retension all the spokes evenly. If left after step 1, the spokes will likely be over-stressed and will fail prematurely.Make mine an Italian, with Campagnolo on the side..0

Cheers mate. Any tips for backing the wheel off once I've got it trued? I guess it's just a case of going round backing them all off the same amount over and over again...- - - - - - - - - -

Yes, go around the wheel winding-off each nipple to the ends of the threadMake mine an Italian, with Campagnolo on the side..0

Remember though, if the rim is bent outta shape because it has been abused, it will be impossible to get both a true wheel and even tension.0
