That is one thing I hadn't thought of and I happen to have 3/8 and 1/4
inch disconnects. I think I will put the 1/4" fittings on the regulated
air and long air hose with the 3/8" on the unregulated and 50 foot
hose. I can always coil up the 50 footer and put it back by the air
tank or better yet in a drawer in the work bench.
I think this is by far the most simple and fool proof.
As to working alone with the high pressure I may just wire in a kill
switch and solenoid, but something simple.
Now I still need to find a dryer that won't cost me an arm and a leg
so I can use the regulated air for painting with out having to worry
about fish eyes.
