I wanted it to be robust as well, and indeed even after I thought I had completed it (...) (21 years ago, 25-Nov-03, to lugnet.technic)

I built my model to test the dual axis control mechanism I came up with that (...) (21 years ago, 25-Nov-03, to lugnet.technic)

This would regulate the amount and speed of the air entering and leaving the cylinder. Hope this gives you some (...) (21 years ago, 12-Dec-03, to lugnet.technic)
