Simple Working Models Of Historic Machines
"The pages present succinct descriptions, drawings and photographs of about three dozen marvelous gadgets from the heroic history of technology, all realized as working models. There is no attempt to follow scale, materials or finish in authentic detail; the aim is to abstract and exhibit the 'particular go' of each machine. Most of the devices are to be made at the woodworker's bench, with some sheet-metal, plastic, rope, or hardboard parts. A number call for machined metal gearing that is beyond amateur skills; one can criticize the absense of much effort here to help young people take advantage of the rich marketplace of manufactured parts in our technological era. The book is nonetheless a pleasure and a challenge. Who would not like to see working models of the device used to generate screw threads without copying any existing thread; of the Chinese spoon-tile hammer, an automatic water-power scheme still familiar in Japanese gardens, or of the Cornish man-engine, a vertical moving belt of miners, forerunner of the mine hoist?"
"This book will be a delight for anyone who is interested in the history of science and is mechincally curious. Isometric and a few oblique drawings are presented for working models of 35 machines.... The model maker is allowed sufficient leeway for his own improvisation."
