| (...) Thanks, Kevin. Had to break-in as matters seem to be getting outta hand. It appears we're getting a new generation of pneumatic fans. Great! (...) No, you use them the same way. The pneumatic switch is basically a directional control valve. It (...) (19 years ago, 19-Nov-05, to lugnet.technic)

In real-life pneumatics, this port would be brought out (...) (19 years ago, 19-Nov-05, to lugnet.technic)

| (...) Hi Dr. Soh, Nice to hear from you. I've never actually built with the original pneumatics, but my understanding is that the way to use switches in the old pneumatics is different than the way you use them with dual ported pistons. Don't you (...) (19 years ago, 18-Nov-05, to lugnet.technic)

Namely, it has a fourth exhaust port that's inaccessible. You'll have to plug up this port for your (...) (19 years ago, 18-Nov-05, to lugnet.technic, FTX)

Would this need to be done in, say, an accumulator (...) (19 years ago, 17-Nov-05, to lugnet.technic)
