David,
Sounds practical. This is a common addition on hard core 4WDs. Even a lot
of aftermarket system distributors IIRC. Have to have air for tires and air
lockers. However, R-12 and HCFC-134a systems use miscible oils that combine
with the gas and get entrained throughout the whole system to lube the
compressor. So, just add a lubricator to the intake and a trap on the
outlet. Hook up a pressure switch to the electric clutch. Better way to go
is with a York compressor (has a sump, but heavy cast construction) and a
scavenging oil line from the trap back to the sump. I'd sell the VW AC comp
for $$$ and get a low $$$ 'merican compressor from a junk yard. Only
comment on the tank is I've seen them used for all types of stuff. I would
want it purged with inert gas (N2) first. Don't know about legality. There
should be plenty of 4WD people/groups in Quesnel to help with this type of
project. I would imagine you could get all the parts you need from Princess
Auto. BTW, If you're in Canada and you don't know about Princess Auto,
you're doing yourself a great disservice...
