Wheel truing the Magnum way

[DEFENDER01]

Having never done wheel truing before i was surprised that when you take your time and only do small adjustments at a time its not such a black mysterious art that some people make it out to be.
I found the trick is to loosen the opposite spokes to the ones you are going to tighten.
And this is the bit i liked which involved having to have a nice Magnum to obtain the lolly stick.

Good tip is not to keep the lolly stick when the job is done so next time you need to have another.

Sometimes loosening the spokes on the opposite side it's what is needed but loosening spokes is not the best approach as an ideal method. If loosening is what is needed then so be it but it can be a bit of loosening and tightening or simply tightening.

And yes, it's not so difficult

The problem with loosening the opposite spoke is that the wheel's outside diameter will now show some run-out (a hop, as most people call it) which your magnum stick will not show. Generally, we don't loosen the opposite spoke because spokes don't tighten themselves, only loosen themselves. Therefore, to correct the problem you have to undo changes, which was a nipple that loosened, not make more changes that hide the problem.

Noooo dont tell everyone - how we gonna make a living now!!!

Opposite side is good for getting rid of eggs, but for laterial if one requires 1/2 a turn, you should tighten it only 1/4, then losen the ones each side by 1/8 therefore giving your 1/2 turn equiviallent.

Otherwise you can end up trying to twist the rim between nipples as opposed to letting it be guided by them.

Hmmmmm..... 1/4 plus 1/8th = 1/2?
Twisting the rim between nipples?

I hope you are not making a living from truing wheels or teaching fractions.

1/4 + 1/8 + 1/8 = 1/2

Did say each side, not just one side.

1/4 + 1/8 + 1/8 = 1/2

The word you are looking for then is adjacent. However, we have already discussed why it is not a good idea to loosen spokes in a wheel that was true, but now has a wobble. It is because spokes cannot tighten themselves.

I'll leave it to the experts.

This video show loosening and tightening which is the way mine worked i now have a perfectly true wheel so i guess whatever way works best for you.

Yup, he looks and sounds like a true pro working in a professional workshop. What you and he have achieved, is as impossible as lengthening one side of a triangle without altering any angles or changing other side, yet still end up with a perfect triangle.

It doesn't matter what method you use or what seems to work for you, it is impossible. Your wheel is either not perfectly true in two dimensions or you have defied science. But hey, some people can do that.

I watched the video and I think the method is flawed. Assuming the wheel was true vertically and horizontally before it developed the problem then I would be plucking the spokes on the opposite side to determine what spokes has/have lost tension. That would be my first step, then I would determine if the spoke/s I just tightened are about the same tension of the other spokes on the same side of the wheel, if they are then that's it but if they aren't then I would try to distribute the extra tension amongst neighbouring spokes while keeping the wheel true horizontally and vertically. I admit that I mostly rely on the tone of the spokes and that is what I do, you can use a tension meter if you like.

Working on cars for most of my working life i defy science most days especially on the modern cars.
