"Cranky Machines" explores the fascinating world of aging mechanical systems and their enduring relevance in modern industry, challenging the common assumption that newer equipment is always better. The book presents a compelling analysis of how legacy machines, some dating back to the early 20th century, continue to play vital roles in contemporary manufacturing and industrial processes.

Through detailed case studies and technical analyses, it demonstrates how certain vintage equipment often represents optimal solutions for specific industrial applications, supported by empirical data on reliability and cost-effectiveness. The narrative unfolds across three main themes: the engineering principles behind long-lasting mechanical systems, the economic factors supporting their continued operation, and the maintenance strategies ensuring their longevity.

Drawing from previously unpublished maintenance records and expert interviews, the book provides valuable insights into successful preservation techniques and retrofit planning. Particularly noteworthy are examples like textile mills operating century-old looms and power plants running generators from the 1950s, illustrating the remarkable durability and adaptability of well-maintained mechanical systems.

Written in an accessible yet technically precise style, the book progresses from fundamental mechanical engineering principles to practical maintenance strategies and modern control system integration. It serves as both a technical reference and strategic guide, offering frameworks for evaluating equipment replacement decisions and maintaining aging infrastructure. The work uniquely bridges mechanical engineering with economics and environmental sustainability, making it invaluable for professionals managing industrial equipment and students studying mechanical engineering.
