Giorgio, I look forward to one day being able to add a Fiat 600 with tracks and a Fiat 600 with wheels to the collection,.,

Here’s a little about magnetos for you, Giorgio, i belive it was in this thread we talked about magneto ignition?
This is an old “Wizard” low tension magneto, i have refreshed the horseshoe magnets before, but i wanted to try this, to modernize it some, by “transplanting” neodymium magnets in them.
Cutting and grinding away a piece to give room for the small magnets, this is really hard, a file or hacksaw just slips.
Six cheap neodymium magnets. This needs eight of them, two horseshoes, two magnets on each leg.
Two in place. It’s important to keep in mind the polarity of the magnets, they should be in series with the horseshoe. A compass and a marking pen is good help, but be careful, use a compass you don’t trust in the wild, they can become pretty messed up from these strong magnets.
First horseshoe in place.
Magneto assembled and tested, the good news is my magnet experiment works good, feel really strong force in the armature, bad news is the springs seems to lost their “springyness” and just become hard, i’ve heard this happens to old springs, and these are 100 years old…

thanks dr. göran, for showing the always interesting things you do!!!
how you have suggested, i looked for another reserve magneto for my fiat crawler, and my son found the same model in internet what i have bought…
but this is , from my sight, differnt to yours in construction, i see no horse-shoe magnet, but inside ( the darker rectangular opening) a packet of metal sheets…
is this model brushless?
and has the magnet on the turning axle?
on the designs here seems your model with horseshoe magnet…
can you help me clearing up a bit the fog in my knowledge, before working on it , it is always good to get some knowledge more…
thanks giorgio

Hi Giorgio, yes your magneto probably have rotatating magnets, more modern magnetos have that. The discovery of small and strong magnets made this possible, for example the AlNiCo magnets.
The old horseshoe magnets was very big, and sensitive to rotating forces (cracks or loses magnetizm).
Those magnetos made it possible to use a static high tension coil (could be made bigger, better insulated, and no centrifugal force try to break the windings) and: as you say, no need for brushes, only for distribution.

And more good things: the smaller modern magnets don’t lose their magnetizm over time, holds up very vell.
The old horseshoe magnets loose their magnetizm over time, or when being dropped, or when heated up, or from vibrations, or when storing them without a piece of iron shorting them.

You have officially blown my mind Goran.

göran, thanks for clearing the fog…in summer probably i will begin the work with the crawler,
stainless pieces just found…but now have preference preparing the garden, and than the motorcultivator needs his gasifier…
ciao giorgio

I like that “Dr” part, Giorgio! If we all meet next summer we should get Göran one of those tall hats 
Göran, you really have in depth knowlidge in many areas. I’m impressed.

Hi Giorgio, i just wanted to thank you for this great tractor pictures, it’s your son thats collect them if i understand correctly? Thank to him also.
And a question: i got a lot of woodgas tractor pic’s in my old books, are you interested in me posting them here? Or do i “hijack” your thread?

Some more.
Gasifier conversion at dealerships shop.
Munktells ad.
Oliver tractor powering a towed thresher/harvester, observe that it’s used as a stationary thresher, probably due to lack of power.
Bolinders gasifier ad.
Ford gasifier tractors, at a big farm in southern Sweden.
Detail of start-up blower, the round container in front of steering wheel is gasoline tank, for easier starting, and to inject some “extra boost” when needed.

Some new’er tractors.
Bolinder-Munktell 35 or 36, converted to woodgas as preparedness for emergency fuel-crisis, diesel engine, diesel fuel pilot ignition, 1950-60s somewhere.
Volvo BM 650 converted by SMP in the -70s, diesel fuel pilot ignition.
Observe the cloth hot-filter, made from a semi-truck air-cleaner.
