(...) Drive + steering just got better! I could use this with an 8 wide steering rack using the 24t bevel gear drive system! It would probably be in a 12-14 wide truck. But will the transaxle work without the motor, I mean just functioning as a (...) (21 years ago, 1-Jun-03, to lugnet.technic, FTX)

(...) Hi Paul, I look forward to seeing your reversible engine. I looked at the Walschaert valve gear. Wow, that is hard for me to understand, even with animation. With longer tubes, I could have easily hooked the two multiplexers to the same (...) (21 years ago, 1-Jun-03, to lugnet.technic)

I"ve been putting together stuff for my pneumatic presentation at BrickFest. How unlike me to be preparing so far ahead. I put together two kinds of pneumatic gates, AND and OR. These gates are minor redesigns of the ones used in PneumADDic II, (...) (21 years ago, 1-Jun-03, to lugnet.technic)

(...) Kevin, This is truly great! At the moment I barely understand it at all. I must build one. Reversible valve gears have interested me for some time. This is not the first reversible engine. I will soon upload photos to Brickshelf. My version is (...) (21 years ago, 1-Jun-03, to lugnet.technic)

(...) Very cool Kevin! Have you thought of using a sliding linkage like steam train valves? It would make it less than 100% pneumatic, but might make it somewhat less complex. ROSCO (21 years ago, 1-Jun-03, to lugnet.technic)

Besides bipeds, I also love LEGO pneumatics. Doug Carlson and I have been trying to work on techniques for making single piston pneumatic engine with little or no flywheel. Doug has been having better luck than I but neither of us have acheived the (...) (21 years ago, 1-Jun-03, to lugnet.technic) !
