The common car alternator can be modified very successfully to produce large amounts of power. This booklet is just 16 pages, but they are jammed full with modifications you can make, and what you can produce.

Learn how you can make almost any ordinary induction motor (like an old washing machine motor) put out 120 volts at 60 cycles without rewinding or internal rewiring. These secrets are worth the price of the booklet alone

Forensic Engineering Investigation provides analyses and methods for determining how something was damaged and when the damage may have legal consequences. It covers 21 of the more common types of failures, catastrophic events, and losses that a forensic engineer may be called upon to assess. Each chapter is self-contained, highly specific, and succinct.

Yes! You can run three-phase motors on single-phase power using any one of three excellent methods in use since the turn of the last century. First, lathes, drill presses, and other machine tool motors can be run with the capacitor method. Second, the autoformer method (a technique you should buy rather than build) is useful for motors running under continuous full load. And finally you can run a whole shop full of three-phase motors from a simple, easy to build dynamic converter! No rewinding is necessary. These methods are good to at least 150 hp and 220 volts! Low starting currents and excellent power factor are possible. This is book is from the USA.

Basic three-phase and induction motor theory is included. This booklet and some experimentation can have you up & running.

Great bargain book of 50 “designs” showing uses for car dynamos and batteries. Make spot welders, electric fences, electric scooters, bench drills, wind generators etc. Whilst the electrical parts of the design are specific, the rest is conceptual, and you will have to use your imagination. Useful and fun! 45 pages.

There is a huge amount of information on all aspects of the early development of the petrol-driven car up to 1909 in the 23 pages of this booklet. Amongst others you get information on the chassis, steering, wheels, transmissions, ignition, motors, and their balancing, all extracted from A Text-Book of Mechanical Engineering, published in London in 1909 although the contents cover British, European and American developments. 35 drawings and diagrams.

Written by Paul Hasluck this book was published in 1907. The book has been re-published from the original and contains the whole script, diagrams and formulas. The book has been reformatted to help reading on the kindle and is not just a scanned copy of the original The formal title is Pumps and Hydraulic Rams with numerous engravings and diagrams.

During the 1960's this book was pulled from all public libraries and banned for sale by the government. The reason was the experiments and information contained were considered too dangerous for the general public, especially young children. The hard copy of The Golden Book of Chemistry Experiments is extremely rare and very expensive if your lucky enough to find a copy for sale.

This educational and fun book shows you how to set up a home laboratory and how to conduct over 200 simple experiments. It is ideal for anyone who wants to learn more about this fascinating subject or for parents who want to broaden their child’s understanding of science.

This great book describes what chemistry is and covers the equipment required, the words used by chemists with meanings and allows you to conduct your own experiments and learn. Each experiment is set out in simple easy to follow steps and tells you what materials you will need and how to do it.

Slightly amended second edition. Nikola Tesla is famous for the Tesla Coil, but another of his inventions is the subject of this book and had nothing to do with electricity, other than as a possible means of generating it. This was his Disc Turbine for which a British Patent, which also covered a compressor variant, was granted in 1910. Unlike a conventional turbine, in which the rotor consists of bladed segments, in Tesla’s machine these were replaced by discs, working on the concept of flowing media being converted to rotary motion by friction working on the discs. Tesla claimed that a very small, but extremely powerful machine was possible using this principle - his aim was to produce a 25 hp machine that would fit inside a bowler hat. Here W. Cairns describes in detail the concept, and the history, of the original engines. He then proposes a number of uses for such turbines, including car and light aircraft use, all of which illustrate the extraordinary versatility of Tesla’s engine. Finally he provides the design and building instructions for a small Tesla turbine which any model engineer should be able to build. Not only does a Tesla Turbine provide a very high power to size ratio, it can be used as a compressor or pump. Tesla used steam on his test machines, and the model featured here would probably be run on compressed air, but the gas turbine principle can also be used; this really is a remarkably versatile machine. This versatility means that ninety four years after the original Patents were granted there are signs of re-awakened interest in Tesla’s machine, as many of the original problems can be overcome with modern materials. What is really exciting is that any revival can be boosted by individual experimenters- here is the place to start! High quality. 34 A4 format pages. Numerous drawings and sketches, including 6 pages of drawings specifically for a small Tesla turbine you can build.
