Hello, Tomk at al,

I've worked out a test that bypasses what everyone thought they were doing
and gets to what they actually were doing.  No time to check it at the
moment, but I'll report once I've done the necessaries at this end.

Hi Steve:

I think the definitive way to answer this would be to look at schematics of
the early cutting equipment. Have you checked the Sooey brothers' journals
at the Sarnoff archive website? Perhaps they discuss this matter?
