I decided to build one.
In the one shed, I found a good tank.
And in another shed, I found an old compressor, which
I tested, and it works good.
It's an old DeVilbiss. That rectangular cap, above the crankshaft bearing, is
where you add oil. It flips up.
I've got the frame welded up, tank modified with mounting brackets, and an
unloader valve on order.
Next, will be the clutch/tensioner and belt guard. I may make it different, so
it covers the engine pto pulley too. That's a nasty pinch point.
