'Go Tell the Spartans'

On the occasion of when a small force of Spartan soldiers
halted the advance of the Persian army and in an act of self
sacrifice saved the various states of Ancient Greece.

An example of determination versus overwhelming odds.

No, now you've gone nuts. <G>

A milling machine is still the better choice for shapes of that
complexity. The real virtue of a shaper is the extreme rigidity in the
planes of interest. Adding motorized rotary motion to either the
clapper or the table defeats that somewhat.

Note that stop point and length ARE programmed, by virtue of defining
number of strokes and feed per stroke.

It would be nice, though, to have the machine go back and forth over
the work automatically ... hmm, I'm finding myself thinking about
writing a Gcode-like language for shapers ...
