Amateur work, illustrated
Amateur work, illustrated is a 1881 handicraft manual published in London and New York by Ward, Lock & Co., aimed at home hobbyists making things with their own hands. Its pictures are plain line diagrams of machines and parts, including an end view of a planer, optical lens sections, a slotted lever on a slide rest, and a stacked wooden block, showing how mechanical assemblies are drawn in cross-section and elevation for a designer studying technical line drawing.
