 Another way to do the same thing is to import the bit map into a CAD program
 (most support this) and then trace the rotor housing and ports over it,
 scaling the whole thing to a know dimension. If you then print out to scale
 on an A3 (2xUS Letter is??) lasar printer, you should have a paper template
 accurate to within a mm or less.

It did not work for me, but I would really like to receive a cad file
of the rotor housing if you got the time.      Jerry
