Lee Valley offers 6 reprinted volumes of vintage Bull of the Woods cartoons. Drawn by J.R. Williams, the cartoons come from his real-life experiences working in an Ohio machine shop (several cartoons are shown in that link to a Popular Mechanics article). The cartoons highlight the hazing, injuries, management issues and other day-to-day hilarity found in the early 20th century machine shop. It’s excellent reading at the end of the day or while sneaking a rest behind the planer. The books serves as a history of sorts as well, showing machines that no longer exist in most machine shops and practices that only the most experienced old timer machinists know.
