Replacement coil for 1924 Elto Ruddertwin

[Tubs]

When questions come up whether something will work
or not, my approach is to try it. The experience can
produce an alternative and may reveal inaccuracies
in what are often commonly held beliefs.
The knowledge from the experience, no mater the result,
is well worth the investment to me.
As you have access to a shear, there most likely is some
scrap steel plate close by that would be suitable to
experiment with. Other than time there wouldn’t be any
investment. No telling what you may learn.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

Thanks Tubs for your reply suggesting trying various ideas. You certainly got me thinking. I Googled “using steel instead of iron” and  made an interesting discovery. Steel will work , but the magnetic field created will not collapse as it does with using iron, resulting in a heat build up that will destroy the coil.

I have found that wire ties used in setting up reinforcing steel are iron, so I will get some and see what happens.

Thanks again for your help.

Part of one of my first jobs was using the hook and double loop
tie wires to tie up 50 lbs. bags of coal. That was many decades ago.
This is the wire I have using to hang parts for painting. I didn’t
know it was iron. Searching iron wire found its also available in
smaller diameters which may be more suitable for what you
have planed if you can find it where your at.

Thanks Tubs for your reply. It looks like were onto something with the iron wire……….I wonder what the effect would be using thin over thick wire? I have just been talking to a friend of mine and he suggested waxing the the wire to stop it rusting.

After doing a bit more investigating, it would appear that it’s important to not have the iron core in on piece, as this avoids what’s called “eddying,” so wire sounds the way to go.  I will get some builders iron ties and see what happens.

Thanks again.

The magneto I put the OMC coils in needs this
tube in the center for a bolt that holds the coil
in the shoes.
I cant say what the tube was made of, or the bolt.
I checked and this is all the leftovers I have.
If you substitute something in the center for the
tube and bolt I believe it should work.
I could slip what I have into and envelope and send
them to you if you want to give it a try.

Sorry Tubs for the delay in replying and thanks once again for your ideas and the excellent photos. Thanks too for the offer of sending the bits in an envelope, but I thinks we will be able deal with that problem should it occure. Unfortunately life has been a bit hectic, what with being down country at Easter and then a dose of bugs and my friend being away still, so I’m not sure when we will be back on the job. In the meantime I hope to do a bit of experimenting with some iron wire

Will keep you posted on progress

Thanks again
