A die filer I built for my lathe starting from a Martin and Morrison casting set and customizing it a bit. The back end is a Morse Taper 2 arbor held in the Tailstock of a 9" SouthBend. In the chuck is a roller bearing crank acting on a scotch yoke. I also added an over arm support and a part hold down arm. Works a treat and it keeps my bench free of machines I don't use often and the motors and belts associated with them. I attached a video link to it running...
Glad to be here.
