Had this “Military” specs Scintilla type coil in the cabinet for a rainy day…… or
a 37 degree sunny day, in this case. It’s the same diameter as the original
Johnson coil, and close to the same length.
Removing the laminate core from the Military specs coil fought me the whole way.
I had to cut off some of the laminate pieces on one end, then start driving them
out with a punch. The punch kept binding up. I ended up switching to using
the tang of a small flat file, which I had to grind down some to make the tang longer.
I finally got the core out, and the coil still test okay on the ohm meter!
I was hoping to be able to use the laminates out of this coil, and just add the
center piece from the original coil, that has the mounting holes for the mag plate,
but that option went out the door when I got out the hack saw. I’ll have to grind
down the original coil laminates to fit, but I had enough fun for today!
Prepare to be boarded!
