Is there a systematic way to balance a prop

SamSam, truly appreciate your replies. It took me an half hour to make the first one (see photo) and it works like a dream. To be honest I never would have thought up, something like using earth magnets, as ball bearing. I used normal small ball bearings. With earth magnets, the sensitivity is much better. Please no critic on my propeller design, I am not finished with the bending and angles. Thanks SamSam.

 

SamSam, You really made my day. I was not only able to balance the propellers quite easy, but also was able to adjust the Pitch ratio (like Gonzo suggested) with a variable angle measuring tool. Time will learn how well they perform on the motors, in the water. Bert
