Actually I think your idea of a automotive condenser coil is good.
One out of large pickup or even a truck. Make it up with one of those
and mount it in front of the pulley on the air compressor so that it
moves air through it and I think you'd be in good shape. If it proves
to be to small you can always go and get another one.
I had a freind make a air dryer for his shop , He took a small water
heater took it apart
cut it in half .Then he took small room dehumidifier emptyed the freon
out of it and put the evaporator coils
inside the tank. Then he weled it all back up recharged the
dehumidifier put the insulation back around the
tank .It works great it keeps the air around 35 deg. I an not sure how
he emptys all the water that codensis
in the bottom of the tank but i can hear it let some air out abour
Easily. Pop off pressure on R-12 is generally 350 PSI. By using the
condenser instead of the evaporator you're using the component made to
take that pressure.
I had one from a failed airconditioner on my house that took me 3 yrs
to get rid of. I finally hauled it to the dump. Would have made a
pretty decent condenser, but for that big assed 220volt fan spinning
the electric meter.

I just drug it out to see how well it flowed and to blow it out. Pretty
decent condenser, but wouldn't flow near as much as the airline I was
blowing out with. I could either get a second one or find a bigger one.
I'll have to visit a junkyard and see what's out there.
