Bill and Paul:

Here are the chord numbers for the Hartzel copy.  I used Bill's
airfoils with only the following modifications:  at station
30 changed from 16-209 to 16-208, at station 33 changed from
16-208 to 16-207.  This made the plot of blade thickness vs.
blade station smoother (took out a little bump).

I have all the airfoils entered in VCADD, scaled for chord.
Once I have them rotated I'm going to DXF export, and a guy
here at work is going to do some Solidworks magic to make
it 3D for Joa.
