With no traveling this Christmas, and all the activity dying down, I was able to spend time on the air compressor project yesterday and today. Made good progress. Compressor is mounted and piped. Control system is piped and working perfect. Tank holds air with no leaks found so far. I only ran it up to 80 PSI in the shop but so far no troubles.
There are 4 unloaders for the compressor. The hydraulic unloader opens until oil pressure builds for easy starting (stock Quincy design). Next the control valve opens at 120 PSI and closes at 110. Then there is a manual toggle to open the unloaders. Finally there is a safety valve fitted to the tank.
Engine got an oil change and a new extended oil drain pipe. Muffler is on.
I need to get it outside for longer runs but this thing is top heavy and moving has to be done with great care. If I leave it out it will be too hard to start. Supposed to be close to 50 this weekend so that might be a good time to put some time on the rig.
Here are some details on the compressor control;
I had to offset the compressor for allignment;
Here is the flex line from the compressor to the tank to allow for vibration and the sliding base. It is a stainless steel bellow with a braided cover.
Finally, a video of a test run. Sorry about it being sideways. I'll shoot another once it is under test.
