Using a rotary table to cut an approximate ellipse?
If you tilt the blank up at an angle a long vertical endmill will cut
a mathematically correct ellipse. The major axis ends will be beveled
so the thinner the stock the better it works.
....
Glad I got a CNC so I just put in the Gcode and cut.
"I THINK" if you also tilted the head, the above suggestion would give you
an elipse with square sides.
