    Default is it possible?

    Is it possible to have a nut with both left and right hand threads
    on the same nut?
    Is this rocket science or can it really be done?

    Sure - that is very similar to a self-leveling fishing reel mechanism.

    The screw thread will follow the path that matches it.

    The thread on the nut will be interrupted twice per turn, I think, so it will not be as strong as a conventional thread.

    The double thread nut would just need to be tapped twice. You can do the same with a screw.

    Would you be able to use a double threaded screw in a double threaded nut? I'm having problems envisioning the engagement.

    Measure twice. Cut once. Weld. Repeat.
    ( Welding solves many problems.)

    Yes. I have the guts at least, if not the whole thing, of what was called a Yankee screwdriver. It has a rod threaded both left and right. The nut was switchable to left or right hand for either driving the screw in or removing it.

    Default I can understand that.

    I can see that on small stuff.
    But I'm talking a 1"x 8 tpi lathe face plate.
    will it be strong enough to take the tork
    of rotational force?

    ...please don't try and double thread your faceplate and lathe to keep it from spining off when you go backwards!

    Might this be for a wood turning lathe, that has a spindle nose on both ends of the mandrel?

    All of the gear, no idea...
