Second Course of Orthographic Projection

The Second Course of Orthographic Projection, by William S. Binns, is a detailed exploration of mechanical and engineering drawing techniques as they were understood in the 19th century. This volume serves as a continuation of Binns's new method for teaching the science, delving into more advanced topics. It offers practical insights into the intricacies of drawing, with specific attention to the creation of accurate and informative technical illustrations.

The book features comprehensive instructions on the projection of shadows and the principles of shading, crucial elements for creating realistic and visually clear drawings. Additionally, it provides specific guidance on the design and representation of the teeth of wheels, an essential component in many mechanical systems. This historical text offers modern readers a glimpse into the engineering practices of the past and remains valuable for those interested in the history of technical drawing and engineering education.
