A. R. switch dimensions and scale them down to 1%4\" scale. Naturally he gets some mighty small fractions, as the original switch starts with measurements to fractions of an inch. The typical model rail will carry the switch lead computations out to the nearest 64th of an inch. Now the lead of an 0 gauge switch runs around one foot or more, and the nearest it can be measured is to the 16th of an inch, so why bother to compute any closer?
