not exactly like that one, but close. I have some questions;
-at what diameter do you measure the pitch?
The scale on mine has 12" scribed in at 45deg, which is only true at a diameter of 1.92". Maybe close for a 7" prop, but what is the accepted protocol ?
-my scale is linear, from 6" to 18",
ie; 6" at 22.5 deg
12" at 45deg
18" at 67.5deg.
High school trig tells me that pitch, ie; rise over run,
is a function of the tangent of the angle,
so the scale should not be linear.
Are your scales linear, and at what diameter does it indicate true pitch?Brian Hendrick, #66 F
