Minimag, another way to get your ignition sorted.

Forgive me if I stray a little from the thread subject.

Roughly 25 years ago I worked repairing all kinds of small and industrial engines. Most of the 4 and 6 cylinder engines (at that time) as well some of the 1 and 2 cylinder engines used magneto ignition. When I say magneto, I mean magneto like the original one on the ground in the Lister engine video Bogs posted.
I remember how much the customers hated those magnetos because they were not familiar with them. I also remember the very robust and reliable spark they produced. I alway admired how well they worked.
I think the minimag kit is perfect for homemade IC engines! It bring back fond memories of the Fairbanks Morse magneto.

Thanks for that Russel.
That is the sort of era I am looking at, where everything had to be, basically, portable and self sufficient.
Can you imagine having to tell a farmer back in those days that he had to recharge a battery. All he was interested in was that when he dug it out from under piles of junk, it would start.

The genius of the FM mag was the impulse coupling that would deliver as robust a spark at cranking speeds as when running at 1000 RPM.

Hi John, after watching the Lister video, I am definitely going to model a magneto for my radial engine. Like so many others who have posted here, I've used magnetos all my life, since a boy with my first Briggs and Strattton, having to remove the flywheel to set the points and clean them, and setting timing as well. To Joe 75 plus, I actually had to go out and charge the battery of my 53 farmall cub, because my charging system only sort of works, and it gets charged about twice a year, when it won't hand crank start. The impulse coupling is indeed true genius, magnetos have been put on Harleys "because they're cool" for all the four decades I've worked on them, but only in the seventies were impulse coupled mags available, and they were advertised as auto-advance magnetos, and substantially ease starting. The "Scintilla" design magneto makes it easier to have the single coil magneto, firing multiple cylinders and enables magnetos for odd number of cylinders. I'm really looking forward to seeing how this build rolls out. :beer: cheers, mad jack

John,
I have to admit this mag would be a fine unit for a larger engine. The key here is 'larger engine' I followed your original posting on HMEM and went to the website to gain more information about the mag. I feel it would be quite a nice addition on some engines.
Now to your sour grapes attitude about the other forum. Why didn't you just say there didn't seem to be much interest and leave it at that. Having followed this and the other forum for some time I find there are a great bunch of talented people on both but not many people build 'large engines'. I just finished a 1/3 Galloway engine and the mag would probably look just about right on something that size, (10.25 flywheels) but in the modeling community not everyone has the tooling or abilities to build something that large. Most builders work in the smaller sizes because it's much easier. I'm sure Lou Chenot (Deusenberg fame) would take great umbrage that working small is not acceptable.
One last thing, could you point out where the 'dogs' were posting. I must have missed that.
