You probably have a lot of good technical experience to share as long as you leave out the agitprop.

Very nice examples.

Good photography. There are more types you can add!

Another interesting reference, my old _Scientific American Handy Book of Facts and Formulae_, Munn and Co., New York, 1920 lists 28 types of gears. Type #8 is 'angular gears', and the illustration shows two squares with gear teeth meshing... and type #22 'intermittent bevel gear or mutilated gear' is just... disturbing.

And then there's type #17, the 'globoid gear' for continuous variable speed control...
