After some research, I proved to myself that small pneumatic pumps are best for motorized compressors (what a suprise, Dr. Soh was right ;^) For those who are unaware, Dr Soh, is a long time LEGO pneumatic entheusiast, who is particularly interested (...)

Hi Kevin, Your compressor is very nice. I am fascinated by your crank. I hope I am seeing it right. It seems a very clever way of getting the amount of travel right and allowing the use of those pulleys with cross holes to connect all the piston (...)

(...) Hi Paul, THanks for the feedback on the compressor. Yes. There are actually two independent compressors that share the same structure. (...) Kevin (19 years ago, 14-Aug-05, to lugnet.technic, lugnet.robotics)

(...) While at Brickfest, Nathan shared his knowledge of radial engines with me. My future radial designs will have an odd number of evenly spaced pistons/pumps. I knew that one critical issue was that the piston shaft needs to point at the axle of (...) (19 years ago, 16-Aug-05, to lugnet.technic, lugnet.robotics)

(...) Hi Kevin I've just been studying the pictures again and they gave rise to a few thoughts. The broken hoses, I'm assuming you mean they pop off rather than suffer fatigue cracking, so is this because the pressure generated inside can become so (...)

(...) Hi Steve, I literally mean broken. I changed some of the beams to get a different color, and in thbe process created a hose cutter (not unlike a paper cutter) and unwittingly sliced hoses. Once fixed, I never had problems with hoses popping (...) (19 years ago, 20-Aug-05, to lugnet.technic, lugnet.robotics)

(...) Hi Geoffrey, It was neither kind of cut. It merely did a partial cut of the hose. THis is worse because it is not as evident. Kevin (19 years ago, 29-Aug-05, to lugnet.technic, lugnet.robotics)
