Multi - pitch props?
 

I measured a Dynathrust 18 X 8 with my prop pitch gage and here's what it measured at these diameters. Notice how the pitch is a little off in the 9" - 12" stations. But what I really wanted to know, has anyone measured the pitch stations along a 18 X 6-10?

D X P
14 8 This is as big my Prather gauge would measure
13 8
12 8-1/8
11 8-1/4 Notice the burbble along here?
10 8-1/2
9 8-3/8
8 8
7 7-5/8
6 7-1/4 Notice how the pitch decreases towards hub.
5 6-1/2
4 5-3/8
