Ok, Perry

    I found a diagram with how pitch is measured.  It looks like its
measured from a surface parallel to the face of the propeller to the

chord

of the blade at each station point.  I will take those measurements at

3"

stations out from the hub center line.

     Hi, Ed.....I have a gauge made for measuring prop pitch made by Warp
Drive.  It is approximately 10 inches square with a large graduated circular
protactor gauge in the middle with a level.  I use it to set the pitch of
the prop on my Air Command gyro. It has provisions for clamping it onto the
prop with the attached wing nuts, and you can measure prop pitch, then put
it on the opposite blade and repeat. It is quite accurate. You can move it
up and down the blade, of course to obtain measurements at different points
on the prop.  Just be sure to have it positioned an equal amount of distance
from the prop tip on each blade, of course.  I can send it to you if you
desire to use it.  Paul Conner, Mobile, AL>
