The pumps do not achieve full range of motion. They expand completely, but
do not contract completely. This is because the pistons are not perfectly
placed away from the center, so the extra length of the unused throw allows
the small pulley that hooks all the pistons together to twist.

I was wondering about that.
Wait, that doesn’t seem quite right.
They all connect together, and that assembly is attached to a medium pully,
right? So, the assembly moves back and forth (actually, in a circle) two full
studs. Is that the complete distance of travel for a small piston?
At each point in the circle, one piston should be fully extended, and another
fully contracted. So it shouldn’t be possible for the pully the are all
attached to, to twist.
Anyway, it looks nice. Have you run it?
