What Grandpa Knew — Harold Calloway
A $39 digital trade manual reconstructing the everyday repair and maintenance knowledge once passed down informally.
Field notes
The book is organized as a practical sequence through the bench, hand tools, sharpening, wood, household repairs, leather and cloth, shaving, and basic engine work. Its stated source base includes trade manuals, shop syllabuses, apprentice handbooks, patents, maker catalogues, and household books. The page says each subject receives one page of instruction and an accompanying picture, and explicitly avoids recommending brands so readers can work with tools they already own.
