A customer brought in a rear wheel from a Vision Metron 81 for service.

When people hear "Metron," they probably think of that scene with the chabudai table and the spaceship behind the sliding door... but that's probably not related to this.
As I mentioned before (→here), it finally showed up.

Anyway, the customer had asked a nearby shop to true the wheel,
but they really messed it up, so they want me to fix it.
The lateral runout is actually pretty minimal (though there's still some wobble for work that was supposedly done).



There's definitely serious centering issues.
The non-drive side has lower spoke tension than the drive side,
which would normally make lateral truing easier with just tightening... or so you'd think,
but this rear wheel has a 2:1 spoke pattern, so the tension difference isn't actually that significant.



Fixed.
Most of the work time wasn't spent on centering, but on truing the radial runout.
When hanging vertically, it was bouncing around way more than it should have been,
so this is really (as I always say) the result of focusing hard on lateral truing.

If you can't build a wheel properly, you shouldn't be able to true one properly either,
so please, just don't touch it.
