I recently acquired a “new” ShopSmith – a 1960s-era model that was in rough shape, and more or less “totalled” in terms of how many obscure parts needed replacing. However, it made an excellent donor machine and upgraded or replaced some key parts of my own 1950s-era ShopSmith.
The most useful thing about the old machine was the hinged piece at the end of the stand. I was able to use it to build a motor-servicing stand: a wooden frame to help slide the headstock onto the stand, which would then hold the motor tray. The stand itself allows the headstock casting to be held vertically for easy access to dis-assembly and cleaning.
