Glenn just incase Ron doesn't have it, you can do the math yourself but the charts would probably be a great help. You take what ever your reading is on the dial indicator and multiply that amount by the segment of the circle or if you have the amount you sweep the sylist on the prop ie: 45 degrees, 45 degrees equals 1/8 of 360 degrees, so if during that sweep you move .125" you would multiply .125 x 8 = 1.00" of pitch. The first pitch gauge I built (mid in the 1960's) for full size props, would only move the prop 45 degrees and didn't have a dial indicator but used 2 pointers and a 6 inch machinist scale. When I started running toy boats I replicated the same thing but used a 1 inch stroke dial indicator. Later I added a protractor that would allow measurement in all areas of the blade from leading edge to trailing edge.
Thanks, John
