Well now–two more clues coming, one on Tuesday and one on Wednesday. So here is something to nibble on…

Sure they can stick to it. One magnet on either side of the aluminum and they will stick to it like a charm.
I think it needs flames on it. You know – to go with the helicopter theme…

John,
One quick guess before I head out the door to join up with Peter and Cooter for some smelt fishing; The CT-17 is a tool for powerless rip cuts. That’s my guess and I’m sticking to it. Unless it’s wrong then I’ll guess something else!

Well, as to the “Flapper” part above – my guess would be that a drill rod (1/8″ to 3/16″) would slide into the circular tab above.
If it were longer the element above (the Flapper) could act a hinged lever.
The angled edge you see on the other side could be the resting edge for this lever.
……and as to the magnets, yes having one on the other side would help its stickiness but so would a magnet-able metallic sheet that could also slide into that circular recess do the same thing.
On the other hand that could cancel out my drill rod theory.
sheeez, only two more days of this!

A helicopter’s rotor hub is a complicated mechanism. In addition to powering the rotation of the rotor blades along the vertical axis, it must also slightly rotate the blades along their own axes, in a once-per-revolution ballet that transmits control motions from the operator to the blades.
The plug cutter-like part is clearly the analog of the helicopter’s rotor hub. It rotates along its axis of symmetry, and drives the mating piece while at the same time allowing said piece to “float” vertically in the eggbeater slots.
Today’s piece is some kind of swash plate, which converts the rotary motion into reciprocating motion.
What does it all mean? I’m not sure, but there are a number of space curves (conic sections, etc.) that can be generated by means of “helicopter kinetics.”
I can see some helicopter inspiration in this part. It reminds me of a rudder.
