How to build a WhirliBriggs, vid shows ideas on what is required for the camshaft, air connection, balancing plate etc. Note. running a WhirliBriggs can be dangerous, since moving parts are in the open! It has enough power to bite very well, even on only 50 psi of compressed air. I don't recommend running the pressure above 50 or 60 psi, as all it does is hold the inlet valve off the seat wasting air. It will run down to a very slow speed, if the cam is made correctly. The air inlet valve will only lift a bit more that 1/32" off the seat, but it still lets in plenty of air. In tests I did with my compressed air engine, the maximun speed I got was 1100 rpm, down to about 100 rpm. I wouldn't recommend attempting to rev a WhirliBriggs up that high in case something lets go!
