RE: Balancing Mejzlik Props?
I have the top of my workbench stock vices level, and smooooooth as a baby's butt. Put a 10mm hard tooling ejector pin in the prop hub and let it ride on the vice jaws. I switch sides and rotation direction, and get a good feel of the prop that way. No rocket science, but a snippet of paper of 1/2 square inch will turn a well balanced prop either side.
In addition to the "DOD method", I also check blade track, blade angle and blade geometry to get all dynamic properties balanced. Using Menz-S props forced me to do that, and now the habit sticks.
