Sometimes it is not easy to get perfect geometry out of LEGO.
I’ve been wrestling with geometries to get the pumps just the right distance
apart, and also having the compression strokes force the pumps through thier
full range.
I ended up using a little geometry and trignometry, and a C program to help run
through the possible geometric combinations...... Never done that before.
I’m getting closer. Given all the play in the central radial connector, we need
more than a two stud throw to compress the pistons. A radius of 1 is not enough
to completely expand/contract the pistons through the full range of motion. I
tried a radius of 1.5, but it was too much. By hooking 1x2 liftarms to 1x2
(perpendicularly) I’ve got a radius of the square root of 2 (more like 1.414).
It works pretty well, but the radius is just a little too long. I’ll see if I
can back the pistons out about .1 stud.

You should post a screen-shot or two. I'm interested to see what kind of data you came (...) (20 years ago, 16-Jun-04, to lugnet.technic, FTX)
