That sounds cool I've never heard of that, I'll be sure to have a look. Certainly sounds like a totally alternative method of making bikes
Here's the best article I have found about Schwinn electroforging. It shows the process in pretty sufficient detail:

And here's a video showing a brief view of the process being used to attach chainstays. Around 0:17 to 0:27.
I think the discussion at the end of the Sheldon article is interesting. I wonder if they had just hung on a little longer, if we'd have a competitive high-quality lightweight factory means of producing steel frames. Or would cheap labor nullify any gains that could be made from machines? Who knows.
