Build a Silent compressor from Junk. Tech Week Special

Here is one that is by no means silent but is a gasoline powered compressor built from an VW motor.

I built on years ago. It supplies enough compressed air to run a TIP 99er sand blaster and then some. only problem is it is noisy. The Neighbors just love it when I am working away with it. I built it onto a trailer so that it can be transported easily around to where ever I needed to use it. I also set up my Air manifold system in my shop to send the air back inside should my main/regular compressor die.
