Working drawings were used to take notations before the master drawings were modified and re-issued.
Parts Detail with notations
In the parts drawing, the two notations on the lower right can each be enlarged to be read. They note various changes made by A. T. Bacon, Charles Vander Woerd and Duane H. Church. You can click on the drawing in any other spot to enlarge the entire drawing. Drawings show the three steps of finishing each part shown.
Early Automatic Lathe Drawings
The automatic lathe drawings are on paper rather than on linen and are from a much earlier time. You can click on the upper right drawing to make it larger, or you can click anywhere else on the set of drawings to enlarge the entire set.
