There are generally recognized hazards in every pursuit of machinery operation, construction and repair. And in this project you will be exposed to the dangers of electricity as well. There is a possibility for fatal electrical shock, fire or other injury and property damage when working with electrical current available at ordinary household outlets.

If you are not knowledgeable and skilled in working with electricity you should find professional help for that portion of this project. And you should check local electrical codes and insurance underwriters rules before plugging in a home built electrical device. Bear in mind that the author is not a scientist or engineer and that no amount of professional engineering has been applied.

This book is intended to describe the author's experience and discoveries for the benefit of others interested in a similar pursuit. While the intention is to present a safe project, no attempt has been made to discover and reveal all hazards. You are entirely responsible for your own safety and the safety of others who might come in contact with equipment you build and operate.

This is another offering in a series of HOW-TO manuals intended to provide basic information to individuals working at home. Most of the information gathered for these projects is taken from out-of- print material and may be considered obsolete in the modern world of high technology.

However, our pursuits in the home shop are usually for pleasure rather than profit. And the efficiency and economy that might be possible with modern methods is not a vital consideration in a non-commercial project. We can be content to have achieved our end by simple means since modern methods may very well be beyond us technically, even if we could justify the cost. And it may even add to the personal satisfaction if we are able to achieve by simple means that which others can only stand in awe of.

And it is never done single-handed. So here I offer thanks to the many friends and readers who offer suggestions and encouragement. And special thanks to two major contributors to this project:. Don Cokley, who worked dilligently on the research and every detail in building the prototypes. Al Shepard, who did some of the machine work. There are few mechanisms more fascinating than old internal combustion engines. And equally fascinating are the ignition systems that enabled them to run.

While countless thousands of the old engines have been broken up and melted down to be resurrected as more modern machinery, it would seem that they might easily have run forever had it not been for some mysterious failure in the ignition or fuel system. In fact today many of the relics are being rescued from the scrap heap, and determined people are restoring them to running condition.

Fuel systems are generally easy to troubleshoot and restore by simple cleaning and perhaps making a small part or two. Battery ignition systems, too, are straight forward, and any able mechanic can determine by simple tests whether the coil and condenser are good and if the points make and break properly.

But if the engine is equipped with a magneto the challenge becomes greater and it will be necessary to delve a little deeper. It is the purpose of this book to reveal a few clues to aid in solving the mystery of those. Like all mechanisms, a magneto is designed to do a specific. It would require a large book indeed to describe and fully illustrate the various types of magnetos. But I will have to leave that book for others to publish.

The main intent here is to detail construction of the equipment for restoring the vitality of the magnets. But a few broad and general tips will be offered to guide those who are completely in the dark about magneto ignition devices.

In all of this discussion it is assumed that you are working with old engine magnetos that will seem rather complex. But they do not differ in principle with modern magnetos as found on the usual engines of lawn mowers, garden.

However while. And so also is it difficult to find specifications and service data for old machines. So then it becomes necessary to be very cautious and observant so that.

Even though the magnetizer is the main offering in this book. However magnets do lose their magnetism for various reasons and in that event it will be absolutely necessary to re-magnetize them.

There is nothing at all new or original in the design of the magnetizing device detailed later in the book. In fact a very similar device was most likely used when your magneto was originally manufactured.

The only significant difference would be the modern solid-state power supply. Since the pole pieces of the magnetizer are adjustable the device can be adapted to nearly any ordinary magneto or magnet. Further, specially shaped poles can be installed and adjusted to adapt to many other designs including flywheel magnets and bar magnets. And of course it can be adapted for experimental use or for production of many permanent magnets for a wide variety of purposes.

A magneto. Then they conceal its true identity with code numbers and letters that would stump agent , and then proceed to design a replacement that will obsolete the newest thing developed even before it hits the market.

The things are designed to self-destruct if you apply a test meter to try and figure out if they are any good. If you break them open there will probably be nothing recognizable inside. And if you brought one to the feet of the Oracle at Delphi in the hope of learning something about it he would probably shrug his shoulders and advise you to devote your time to something more worthwhile. But you can understand and repair engine magnetos. Magneto ignition systems are actually not greatly different from battery systems so basic troubleshooting is much the same.

Such are modern computerized systems. Or at least that is the claim of those who build them and foist them upon us. A computer would prove of little value in diagnosing magneto troubles.

But everything you need to know can be quickly learned by- simple tests. And when these simple tests indicate that all. But bear in. And, more. In fact you can lose a significant amount of magnetic strength by simply removing the magnets improperly.

And reinstalling them backwards can get you into some very serious trouble. Dropping a magnet or striking it with a hammer can also effect its strength.

And excessive heating, as with a torch, can completely demagnetize the magnets. The discussion on basic trouble- shooting and repairs will be general and brief but you will get full details on building and using the magnetizer a bit later.

The best rule to follow is to always leave the magnets undisturbed until you have thoroughly considered every other possible cause for. A magneto is essentially a. As the name implies,. Magnetism is. While its actions can be compared with those of electrical currents there are distinct differences that have challenged great minds for centuries. The first natural magnets are said to have been discovered in Magnesia, a small country in Asia Minor, around B. Knowing the origin and date of discovery helps not in the least except that we can impress people who did not know that already.

And knowing the origin of the name frees the mind to look for more valuable information since we don't have to wonder why it's called magnetism. A great deal has been learned about magnetism in the past centuries but much remains to be discovered. It is theorized that molecules are aligned within the body of magnetized materials so that the attracting and repulsing forces of the electrons are concentrated and polarized.

Nothing can be gained from a discussion of theory except that we might finally agree that one expression of theory seems more plausible than others. But while little is known or understood about what magnetism is and how it works, a great deal is known about its effects.

That knowledge is useful in a study of magnetos. Very rich. Early sailors discovered that an elongated piece of it hung from a cord or floating on a block of wood in a pan of water would always orient itself with one end pointing north and the other south and thus the first magnetic compass was invented.

They called it a "Lodestone", which means "Leading Stone". And the same law applies. Understanding these laws is vital to an understanding of induction. Modern manufactured magnets are many times stronger than natural magnets and they are made in an infinite variety of shapes and sizes. Many other uses have since been found for magnets and a large proportion are used in electrical and electronic devices. Just as an electrical current is induced when a conductor cuts a magnetic field, so is a magnetic field induced each time an electrical current passes through a conductor.

Generators and transformers function on these very basic principles. And a magneto is really a generator to supply a.

A typical magneto has a set of. Of particular interest to us is the fact that when a magnetic field is cut by a conductor an electrical current is induced. You can prove that yourself by winding a small coil of about 10 turns of insulated wire and connecting its ends to a very sensitive milliamp meter.

Then pass a strong permanent magnet back and forth over the coil or through its center and watch the meter needle deflect. Actually the magneto is more precisely an alternator that produces an alternating current at low voltage to be built up to a voltage high enough to discharge a spark. It is the rapidly changing magnetic field that induces the current. And the greater the number of turns in the coil the higher the voltage. So also, the faster the magneto spins, the higher the voltage.

The rotor is wound with a coil of wire that represents the primary of a transformer. As it rotates. The magnetic polarity of the magnet has a.

Magneto Magnetizer

The cores of the electromagnet are made of soft bar steel one inch in diameter and three inches long. All contacting surfaces should be absolutely flat and square so that there will be good metalic contact over the entire surfaces. Before the wire is wound on them, the magnet cores must be insulated. A spool may be formed by placing fiber or cardboard washers around each end of the magnet cores and then wrapping the magnet cores themselves with several layers of electricians tape.
