Real good progress George.
As to your leaky compressor, try using white Teflon plumbing thread tape on the threaded connections. I have my compressor in the basement and ran 1/2" steel plumbing pipe from it up to he second floor back porch where my bench is to a regulator/moisture trap/manifold with multiple valves, gauges, and quick release connectors. Its a plumbing nightmare but holds the air pressure good with that Teflon tape used on every screw connection.
