    Yeah….that video was suggested in an earlier thread, and I’m going to give it a try tonight. That guy has a website where you can dump in the numbers and it gives you the pitch. Oddly enough, though, you enter the diameter in inches, everything else in millimeters. Strange.

    Bottom line: Looks like some pretty easy trigonometry; I’ll just do the calcs myself. Of course, this will be AFTER I scrub these props & look for stamped numbers!
