Paul,
I was just thinking about my earlier msg and realized that I didn't say
exactly what I meant.  Bill's design appears to use dynamic tuning
between the rotors, but what I meant to say is that wouldn't it be
better to match the inside ports into one chamber and the outside ports
into another chamber - I think that this is how Tracy does it and that
is how I interpreted the earlier posts here.  What does everyone think?

  Bruce T. said to match ports to the chambers, not to
the size of the ports.  It makes sense.

Actually Tracy and Bruce did the design.  I talked to the machinist.
