Hi Ice,

FWIW:

1. In first taking into serious consideration that inflated rubber tires can flex slightly, if one's outer rims are bent in or out, false readings may be obtained.

2. One better way of checking Model A wheel lateral run out, (wobble), is to verify if wobbling is occurring "near" the "center" of the wheel and tire as opposed to what is happening on the possibly bent protruding outer rim which is, in many cases formerly damaged after 80+ years of service.

3. Rather than set up a fixed jig "only: on the most outer side of the rotating rim, set up a jig either:

A. On the metal surface of the rotating wheel, i.e., closer to the center of the tire recess, near where the spokes penetrate the wheel; and again, closer to the center of the wheel; or,

B. On the front or rear of the rotating rim; i.e., closer to the center of the rotating wheel between the inner and outer wheel perimeter rim where the tube fits in the wheel.

4. No doubt many Model A wheels were discarded simply because one found wheels with only the outer rim damaged and bent in or out more than 1/8" ..... however, if the center of the wheel would have been checked, these wheels would be within the 1/8" limits.
