Core area must be large enough to saturate the magneto core without becoming saturated itself. Many many years ago I worked at a shop that built these as well as just about magnetic device you coud want. What Dave has done is show you how to build a proven device from currently available materials, and at low cost. If an ammeter is used, it should be placed away from the coils so the magnetic field won’t affect meter accuracy.

Webster Tri Polar Oscillator in position for charging. Description The charger described here is designed to operate from a volt automotive battery, has a core area of seven square inches and provides 20, ampere turns of energy. Note the automobile battery for power and a compass for checking magneto polarity before charging. John using the charger at a local New England engine show. No idea if this of any use to anyone or even if it works but when I came across the link by chance I thought I should pass it along to those REAL DIY’ers out there that tinker with the real magical parts!

Maybe you can magnetize that bolt in your neck so you can attract beautiful women.

The windings will heat up quickly when in use; therefore, the switch should be closed for only a few minutes at a time. As everyone knows, opposite magnetic poles attract while like poles repel. Alternator diodes will work fine if the ones listed aren’t available.


Order a copy today. I believe that there are forum rules prohibiting this kind of advertizing so maybe a note to the moderator to get this removed would be in order Construction of magneto chargers is not a new subject for GEM.

We bought the book, did research and actually built one. Mark the poles with the letters N and S to indicate their polarity. If you have a source of scrap iron, machine shop facilities and can come up with some surplus magnet wire, the costs can be drastically reduced. Mark the north pole ‘N’. Inspiring New Engine Collectors.

How to Build and Use a Magneto Magnet Charger

Build a Magneto Magnetizer Many people collect and restore old engines and in the process discover that the old iron magnets in the magneto have lost most or all of their magnetism. With the price magnettizer copper wire, it is not cheap. Check out British motorcycles for sale: Chargers have been described in the following issues: Size and expense make the charger most practical for club or group use.

Once the magneto is positioned, charging is accomplished by closing the switch and letting the current build to a maximum as indicated on the ammeter. Note the position of the magnetiizer pole pieces when charging this magneto. Final assembly Now things start to get heavy, so it’s good to build the charger onto a two wheel hand truck or other cart. The coils are connected in parallel and protected with diode arc suppressors.

These are epoxied to each pole piece. Magneto’s are something dear to me but this smacks of SPAM or at least underhanded advertizing As winding progresses, it will be more and more difficult to prevent the winding from becoming scrambled.


Building a heavy duty magnet charger

After most of the 20 pounds is wound, the winding should be planned so the wire will end magento the terminal end of the coil. The main base is attached to the hand truck using the two pieces of steel angle cut from bed rails.

maagnetizer The ammeter is connected in series with the switch and mounted to the wood base attached to the hand truck. The figures show optimal pole piece placement for charging most popular magnetos. Print Thread Switch to Threaded Mode. Blueprints for an Ironwood Engine. Show All Member Profiles. Note location of auxiliary pole pieces.

Great for engine restorers, science experimenters, or even as a science fair project. An auxiliary set of pole pieces in conjunction with the first set is used in most charging applications and is essential for magnetos such as the Bosch AB and AB This article has drawings and instructions for making and using that charger. Knife switch The choice of a knife switch has one big advantage. We did it because of the challange.

The exact number of turns is not important so don’t bother counting turns, just wind until 20 pounds of wire is on each coil.

Wind the coils on a lathe using back gears and clutching.
