    Pneumatic Air Compressor not working. Suggestions needed. —Todd A. Schroeder
   My CAT 797 Mining Truck is near completion. Everything works the way I wanted accept for the air compressor. I bought new pneumatic parts from PLD and tested my mechanism with the large hand held pump. Everything worked fine so I built a few (...) (23 years ago, 4-Mar-02, to lugnet.technic)

   (...) This is not really true. I think that Boyles gas law is (boy, high school physics was a long time ago): Pressure * Volume = c * Temperature Where c is some constant of proportionality. Plus I think that this assumes some "ideal gas". Real (...) (23 years ago, 7-Mar-02, to lugnet.technic)
