Yes, two cuts run the length on one side edge.

That might let me swing the tile table around! Must clear the Y motor.

Circular interpolation would be fine, if I could swing all the way
around the part! 2 or 3" throat/travel is quite limiting! Oh for a 2X
Sherline Mill! Thought about the EMCO FB-2, that would REALLY kill my
budget! And a Myford-7 and a...

I thought about milling the entire part, certainly could. Partly to
test theory of bolting larger stock to lathe spindle. And after boring
the .375" hole, might be a little better balance to flywheel?
