It looks like all my old images have come back!!!

Here is my nephew working on truing a wheel using the stand that my father made many years ago.



For one reason or another, the stand wasn't designed to be adjustable for wheel width. But, it has enough flex that one can jam front or rear wheels in.

A pen will work as a reference point. Although at one time I found that old BIC razors made the best tone when the wheel hit the reference.

Unfortunately it is very difficult to adjust axial and radial at the same time, so radial accuracy tended to suffer some.
