    I know that stuff pretty well. Back in the earlier days when they started offering the thread rolls, early 1990's, I knocked horns with them for nearly ten years over the problem of the 8 and 10...

    Contour sawing goes way back earlier than the 1940's. I have a DoAll book on contour sawing that came out in the 1930's, so it's at least that old.
