I built my own
compressor years ago using an old truck compressor, and drove it with
a 1-horse 3450 RPM jet-pump motor.

How did you supply oil pressure to lube the crankshaft? or did this
compressor have its own closed sump and pump or splash lube system?

TIA

It was a base-mounted belt-driven compressor that was supplied
oil from the engine's oil system. I made a steel base plate to close
it off, drilled the side of the case and tapped it for a 1/2" 90° pipe
elbow for a filler/level check plug, and drilled and tapped the con
rod caps for 1/8" pipe street ells that acted as scoops to grab the
oil from the sump and jam it into the bearings. The main bearings were
ball bearings and get plenty of splash to keep them happy. The thing
has run happily for probably 100 hours over the last 20 years and
shows no sign of distress.
