Radial tires again

[JRHASZARD]

On my Cessna 180, a conventional gear airplane, toe in is critical. I have four 12"X12" steel plates. I place two under each wheel with grease between each set of plates. This relieves the strain from the tires and the spring steel gear legs. Then the toe in is measured with two framing squares as described by Ak Sourdough. I have done this on the Model A also with good results. I believe it gives a more accurate measurement.
