I knew what you were saying, but I was explaining it for those who couldn't read
between the lines......
I'm going to try a radial design. Medium pulleys have six pin holes, so I
suspect that I'll have two groups of six. I have yet to come up with a way of
ofsetting the two by 45 degrees to get things from 60 degrees to 30 degrees.
The first draft will probably have pairs of pumps at exactly the same phase
seperated by 60 degrees of rotation.

| (...) If you rotate the pulley 90 degrees on the axle, the holes will be in the right place. Another option is to mount the other end of the pistons at 30 degrees (like a rotary engine) (20 years ago, 2-Jun-04, to lugnet.technic)

| (...) While a rotary design will probably be a bit more powerful, laying them all flat could be more versatile. You could place cylinders anywhere you've got a little open space, rather than having to make space for a bulky cluster of them. (URL) (...) (20 years ago, 3-Jun-04, to lugnet.technic, FTX)
