Thermo-Quad metering rod measures

DionR said
Here's a 75-1966 rod. I would have to go digging to see if I have any other loose one, or take one apart.

Did my best with my HF calipers, I suspect there are better ways and more accurate tools. I didn't match the economy step either.

Not sure how the midrange step works since there are only 2 parallel sections. Maybe the long taper midpoint is the midrange step?

Good drawing. Thanks for your effort. If the rod was 10x bigger I would already be on my turning machine. This could probably be done whit a small grinder fixed instead of a cutting bit and turning the supported rod with low rpm. The bending would be the last step hoping it doesn't break.
