Hi Cliff,
Many thanks for the information.
I would have taken over the production of the minimag, as I was about to start making a four cylinder that I was going to fit one to, but due to an accident at work (not my fault) I am left without most of the use of my right arm, and can only just manage to operate my lathe and miller (it now takes 3 or 4 times as long), so I don't think I have the dexterity to make them. It is a shame really to lose such an unique item for such a small amount of cash, which I am sure in the right hands could recoup the outlay and maybe make a small profit, Jim Shelly did for many years, he also designed and marketed a fairly large horizontal twin, I think it was called the 'Maltese Falcon'.
So it looks like you will be making your own magneto.
John

I gave Jim Shelley in the UK a ring and came up with an answer to my question about availability of the MiniMag kits. It seems Mr. Shelley had all the equipment to make the MiniMag disconnected and is attempting to sell the business outright. He has no stock of ready kits, in fact is out of stock of cores, but has plenty of laminations and rotors. The equipment consists of everything needed to make the kit...coil winder, lamination press, vacumn pot, and I'm sure a couple more items I forgot...basically everything needed to make the MiniMag kits. Mr. Shelley's cited his health as the reason for discontinuing production, and he hopes someone will come along to take over the business. He is selling it whole for offers around 5K pounds Sterling.

Hi Cliff,
Jim Shelly who produces the minimag kit was trying to sell it as a going concern about a year ago.
I don't know if he did sell it but it would be worth a call or writing him and get the information.
I have posted his contact (the last ones I know) further down this page.
My email is now john@maljohn.plus.com.

John

Is anybody aware of recent developments of building a magneto to use on multi cylinder engines?

Also, is the MiniMag kit still available?

hi all..
as some may know, we have been looking into and experimenting with magnetos for about 5 years, to do with an I.C project we have been working on. the main parameters are that the ignition system should start an engine at about 500 rpm or less, and work a 2 cylinder engine.this means that the basic minimag magneto really neads modification, jim shelly says that it should be geared up to 2X engine speed to make it run really well. we intend to do this with a 2:1 geared coupling to the engine housing. it also needs a distributor, ad something like edgar westbury's three contact distributor on the back might be good we think. maybe we can put a battery jack in the housing too, and connect a rechargable battery for starting. maybe some sort of spark retard/advance might be a good thing too.. maybe an impulse? Dad is away in sunny queensland for six weeks or so, and we might get into this when he returns.

About the magneto,its finished size as it is designed is about 2.6" high, 1.65"wide, and the shaft 2.5" long. its got a nice ground alcomax IV rotor, and a coil capacitor unit about 1.125 dia. THe laminations are punched,it comes with metric bolts to bolt it all together. bearings, points, springs, insulating material etc is all included.
Jim Shelly is a great guy to deal with, and was pretty quick sending out the kit. i dont know him personally, living so far away, but seems he has a good product going here.

regards, marcus

Hi Marcus,

Can you give us some more info , spec's,etc. on that minimag. It looks very interesting. Maybe I can try it out on some of my spark engine conversions.

We bought a minimag "falcon" machinist kit earlier in the year.. It looks very good, no time to get to putting it together yet though.
Ill post a picture here, some might be interested in what it looks like, as we bought it pretty much in the dark!

regards, Marcus Ritson

Hi Leon,
The information you require is:-

Jim Shelly
Minimag Co.
358 Birmingham Road
Walsall
West Midlands
UK
WS5 3NX
Telephone 0044 1922 628553

He doesn't have an email address or web site but if you write to him he should send you his very informative catalogue.
To run with a magneto the engine needs to be turning at a fair rate initially to produce a good enough spark to sustain ignition, so really an electric starter is required. This is the information Jim told me when I called him about it a few months ago. I am considering fitting one to a 10cc four cylinder engine that I am just about to start to build.
If you cannot get a reply from him send me an email at maljohn@tiscali.co.uk and I will try to get all the information you require.
