Homemade Compressor for Airbrushing

[Frank S]

Once while working part time at a full service gas station an older gentleman drove up in his 48 or 49 chevy complaining that since he had changed his oil his oil pressure was continuously getting lower and lower. I had him park his car over the pit then I pulled the top off the filter only to find a roll of toilet paper. When I asked him about it he said that the old filter looked like that was what it was so he thought he would save the 2 dollars of the cost of the filter. It nearly cost him his engine. I drained his oil and pulled the pan the screen was nearly blocked. So I cleaned everything put the pan back on installed a proper filter filled the crankcase with ATF started the car let it run for a while drained it pulled the pan again cleaned the screen and the pan put everything back together changed the filter and re filled with his favorite brand of oil
For what it cost him he could have had his oil changed properly at the station every 3 months for 2 years, but he did become a regular customer
Toilet paper as an air filter restrictive but good just catch the chunks, toilet paper as an oil filter BAD.
there are several heavy equipment fuel filters that use a cartridge made out of wound string you can even get house hold water filters that use a string wound cartridge
I believe that Grayco still makes an oil separator air filter that uses a string wound cartridge
