Fascinating.

Come to think of it, with a CNC mill, I could make toy gears like this
with ease if I knew how to calculate their shape.

I did a fair bit of poking around with Google on non-circular gears
trying to find some info on designing them, came up empty. One of those
'if I ever find myself with not much to do' things.... lol

that wankel style one in the middle of the video seems to have
potential as an oil pump.

At one time we used a positive displacement flowmeter just like the first
one. It was all 316 satainless and had 4" inlets and outlets. We used it to
calibrate brewing fermentors that were 30' diameter and 90 feet high.Even
with a 4" water line it took forever to fill the damned things and we were
renting the meter at an outrageous cost. Still, it was bloody accurate.
