Many years ago I recall reading a layout tour article published in Model Railroader (back in early 80's before CTT was out) that described a 3 Rail tinplate layout built using simple homemade switches. (before they published CTT, they would include the odd 3 rail layout during the Christmas season in Model Railroader)
I recall trying to figure out from the pictures how they were made, I remember them looking like they were cobbled up from a few pieces of tubular track with some form of swivel frog in the middle. I think they were just manually thrown.
At the cost of new switches today, I have often thought it would be nice to simply "kit bash" them using some left over track parts. Has anyone ever tried this? Would anyone have a design for such an item? Switches have always been an expensive item and I would not be surprised that even in the 1950's people were trying to build their own.
