Most of the home built variable pitch propellers that you will run across will have a .75 inch hub. others will have some kind of external pitch control linkage. all of them have some kind of variable length internal, or dual piece propeller shaft to contol the blade pitch. here is an old diagram from 1964 typical of the genre. Virtually all controllable pitch propellers make use of a hollow shaft that contains a concentric push rod which moves forward and aft over a certain range. via an eccentric in the propeller hub attached to the blades and to the push rod, the pitch of the blades is accurately controlled.. A variable-pitch propeller or controllable-pitch propeller (cpp) is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. a hamilton standard variable-pitch propeller on a 1943 model stinson v77 reliant..
