Scott 16 bail a matic coils

[Kimmer64]

Hi all,

I am trying to refurbish a 1956 Scott Atwater bail-a-matic. I have fire in one coil, but not the other. I saw on http://www.oddjobmotors.com/tt1_replacewico_coil.htm that he was using omc coils to repair these old coils.
He stated that the laminate must be 7/16" square, for this to work.The laminates for my coils are about 9/16" square.
The question I have is would it be possible the machine my laminates down to 7/16" square, and make this repair work. I have a friend who is one hell of a machinist. I have no doubt he could physically make it work. What I am wondering is would it change the electromagnetic properties of the magneto?
I can get replacement coils to fit what I have currently, but they go for about $50.00 each. I can get the omc coils on ebay 2 for $20.00. I am all about saving $80.00, but if I ruin my laminates, there will be no going back.

Thanks
Kimmer

All I can tell you is the reason for the cores being laminated. It is to prevent eddy currents in the induced magnetism. The individual laminated plates are coated with an insulating material to separate them. Cutting them may burr the edges of them over so they contact each other and short them out. How much difference will it actually make??? Durned if I know.

Re: Scott 16 bail a matic coils

Thanks for the info. I decided to bite the bullet and order the proper coils. Found them for $40.00 each.
While I am at it, I am going to order new impellars too. They are $40 each. So for less than $200.00 I should have a pretty good running little motor. This is my Dad's old motor, and hasn't been run in close to 30 years.
I do have one more question. Most of the Scott motors I have seen, of this vintage, are green and gold. Mine is the orangish red color, white on the bottom. When did Scott/ McCulloch switch the color scheme?

I believe somewhere around 1957-ish. I am now looking at a 1957 parts book for the 40hp that shows a choice of white, blue, grey, red, or brown hoods.

I've got a 56 bail-o-matic 10hp, and its now using merc impellers (as you know theres two on the bailers), and they only cost me I think it was $7 each.
