Dimensions

The dimensions given in the list below are those which should be used in place of the corresponding reference numbers in the text. All dimensions might have been omitted both from the text and the appendix; in that case the worker would have been obliged to study the working drawings to determine the dimensions. This method was not followed for fear some beginners might become discouraged before acquiring ability to read the working drawings. If all the dimensions had been given in the text, the worker would not have been encouraged to study the working drawings at all. This would have been equally undesirable. It is expected that a worker will refer to this list only when unable to determine the dimension from the- working drawing or when he wishes to see if he has determined the correct dimension.
