M0xxy makes a mess

Check your local craigslist for an 80 gal air compressor, rip off the old compressor on top of the tank and THOROUGHLY clean out the inside with a solvent to remove all residual oils from the previous lubricated compressor, then attach your compressor to the tank with a check valve. Your compressor will probably fill it's container to 120 PSI, then turn off. Any commercial compressor comes with it's own holding tank. This will save you hundreds of dollars buying a higher volume tank new, just make sure to clean the used tank well.

There has to be a few threads around here addressing these same questions. Give these forums a search, and you will find gold.
