| | | | In real life pneumatic is not used where more than two position is accuired, and when it is done ither more pneumatic cylinders are placed after each other to make more fixed positions. Or there is placed an hydraulic brake on the cylinder to holde (...) (23 years ago, 21-Mar-01, to lugnet.build, lugnet.general, lugnet.technic)

| | | | | | This is really interesting. There are definite differences between pneumatic and hydraulic systems. I dreamed of Lego hydraulic systems before, but I have never anything of it. Could you please give more info on what you did with you Lego hydraulic (...) (23 years ago, 21-Mar-01, to lugnet.build, lugnet.general, lugnet.technic)

| | | | | To make LEGO properly hydraulic, some kind of real hydraulic fluid pumping system would be needed. And it would have to take either water or a special hydraulic fluid. I believe it may be possible to achieve control with airflow alone. But I would (...) (23 years ago, 22-Mar-01, to lugnet.build, lugnet.general, lugnet.technic)
