    I can see that you are a tinkerer and builder for building sake, like me.

    Don't ask me how I know. You can guess.

    Re: Hoss's G0704

    I used a square nut on my 0704, but I don't remember what size. It was rather large.

    I chucked the nuts in the lathe and turned then down until they fit in the bottom of the slot.
