The milling attachment and stead/follow rests came with the 1938 Clausing
I had. I don't know if they're that old, but they look it.
The ball turner, I made recently.
Used a rusty, pitted piece of 2-3/4" stock turned to 2.650"
Didn't get rid of all the crud. Patina? Character?
I silver braze my own carbide tipped tools
Got the bottom plate from the scrap yard.
It works.
