Found a junked 28" piece of 2" X 3/8" steel flat with 1/4" holes 3/4" apart all along it. Thought to cut it in half and weld a 1 1/4" X 8tpi spindle nut to the center of one half and drill a 60 deg. tail center hole in the other. I figure I can fix two balanced blanks between each half the same no. of holes off center and by turning then rotating 180deg. make 'big fat or flat ovals', plus get two for the price of one. :) IOW, the centers are more offset than the blanks would normally allow. What do I do with two big flat ovals, anyway?
I vaguely remember something like this, but before I fracture my nose and/or put another hole in the ceiling thought I'd better ask rcw if this makes any sense. Been done before? Won't work? Too risky? Why bother? Well, my Harbor Freight auto tail pipe expander does fine as an expansion 'pin' chuck, but somehow I don't seem to use it. :)
I know, I know. "Give it up Arch!, just go turn some bowls like normal turners do".
