How to Build a Magneto Magnetizer Paperback – January 15, 2013

Great book on building a magnetizer. One thing to remember you need to wind both coils in the same directions in order for it to work properly. The book does not tell you this and other designs call for opposite coil winding guess how I know!

If you are rebuilding pre ww2 motors you need this machine and you can't buy a working one that will last (original coils will fail and start a fire or blow your breaker) after ww2 they had permanent magnets and these machines disappeared.

This 38 page booklet begins with a few words of general advice about how to diagnose a faulty magneto. Then it gives a simple magnetizer design complete with measurements and bill of materials. In order to build the magnetizer, coils of wire must be wound. The book prescribes a crude, hand-cranked coil winder design, to be fabricated from wood, cardboard, and common hardware.In case you are wondering, a magneto is a small, mechanical generator of electric sparks that works by exploiting the principles of electromagnetism. In the past, magnetos were employed to fire spark plugs in the cylinders of internal combustion engines.If you've got an antiquated engine and you suspect the magneto might be faulty, but you don't really know what you're doing, then this booklet may provide just the fragments of knowledge you need to accomplish a repair.You'll find it easier to build the magnetizer if you have access to a machine shop. Alternatively, you will need patience and determination with the hacksaw and file.This booklet is a great help to novices who are fumbling with a recalcitrant magneto. Prospective readers who are merely curious about electromagnetism might be better served by other information sources. This is a plain book that offers clues to folks who are trying to solve a very particular problem.

Well written, consise, easy to follow, would like to see an updated version with current suppliers list. Over all very good book for antique engine restoring.

If you work on magnetos and want to do it right you need to be able to re-magnetize the rotors. This book gives you a step by step way to build a low cost tool to keep your magnetos running for years.

This is exactly the information and specifications that I have been searching for. The information is clear and understandable with diagrams and measurments. A great sorce of information. Thank you!

My father in law restores old tractors. He said that this was one of the best books he has read. He has already started building one.

All good. Exactly as expected

its an American publication so if you are elsewhere you need to makes allowances. For example he specifies a six pound reel of wire. Wire in most countries is sold by the kilo. The US mains voltage is 110 volts, here in Europe its 220-240 volts so you will need to update the bridge rectifier and smoothing capacitor to suit. . It's a bit lacking in theory. His design seems to output a quarter of the recommended magnetic field strength to recharge a Lucas magneto magnet. But he says it's more than adequate but doesn't include any calculations to justify his claim.The above points apart I found it quite useful from a constructional point of view.
