![]() 431 forum posts 252 photos | After taking my Sanderson all apart and oiling it up and making a few adjustments to free it up, I have got it running on air, sans governor but including the gear train as shown it the picture at the top of this thread. After an hour or so of "braking in" its been running for the last hour comfortably at 32 RPM on 1 or 2 PSI ( hard to tell, the needle on the regulator hardly moves off the stop ). It will actually run slower but is not very regular, I suspect the valve needs adjusting slightly. It's a bit of a pain to adjust as the cross shaft of the valve actuating linkage prevents taking the valve chest off, so to see the valve to adjust it the whole valve linkage has to be removed (for the umpteenth time! I've lost track of how many times so far ). John |
