Hi. I'm Joe, a 55 years old geophysical engineer and I have a hobby for aircraft static modeling, so I'm looking for ideas to make a homemade tank compressor using a refrigerator type compressor for airbrushing purposes.

The piston and diaphragm types run hot very easily and are too noisy and I need a quiet environment to work.

In the recent past I build up one but I had trouble with an oil mist in the air flow no matter what type of oil filter I used.
I want to know what went wrong in the design and have the opportunity to correct it.

I would appreciate and welcome any ideas.

Thanks
