Dynamo!: 2 Books in 1: How to Make a Dynamo for Amateurs & How to Build a 50-Light Dynamo.

This book combines two titles, the first being How to Make a Dynamo by Alfred Crofts, and orginally published in London in 1900. The second is How to Build a Fifty-Light Dynamo by A.E. Watson, published in the U.S.A. in 1895. Crofts' book is considerably the larger and more detailed, and describes the building of a DC dynamo 16 inches wide, and powering about ten 16 candle-power lamps. Mr. Watson's book describes building a big machine with a base around 34 inches long and 20 inches wide. The drawings are better than in the first book, but may have been reduced, as you need a magnifying glass to get some measurements. The drawings in Croft's book are not so clean anyway, and appear to be enlarged, but neither should stop you building the dynamo if you are so minded - and there is also a lot of technical information here. 192 page paperback. 51 drawings.
