(...) Thank you. (...) Well we must agree that the switch solution is a bit gangly. I'd like to work on a more compact solution before I bother with the engine. When simply run on compressed air, the sequencer cycled faster than I would have (...) (19 years ago, 23-Nov-05, to lugnet.technic)

(...) I think I may, if I have enough switches. I only have the contents of one of the new studless backhoes, minus one piston because I broke off the bottom port and can't figure out a way to repair it. Oh, and I also have the pneumatics from the (...) (19 years ago, 23-Nov-05, to lugnet.technic)

(...) Andrew, If you call LEGO customer service, they may replace your broken piston. Well a pressure/vacuum engine will run only on pressure. The vacuum parts would be exhaust pressure to the atmosphere. I did all my testing simply using pressure, (...) (19 years ago, 23-Nov-05, to lugnet.technic)
