Suprisingly, in the back of the local big box toy store I'm working at for the holidays, they have a ts-2 truing stand. There's just one problem, the calipers aren't centered. On closer inspection, the knob that makes the fork ends wider or narrower, the fork near the knob doesn't move, only the left one does, which means any axle not obscenely wide will be off center.

Any ideas how to fix it?
