One of the best models ever!

Check out the world's smallest V12, it even using timing gears like the EG33. Here is an article that goes into the precision and detail into designing this awesome air compressor.

I doubt we'll be seeing a do it yourself kit of this anytime soon but I know there are models like it being sold en mass, relatively speaking.

Saw one slightly larger that actually ran on GAS . The blue prints are the hardest part . a GOOD machinist can do that . The guys I worked with back in the day would have no problem with it . They worked in .0001
so did I. On an EDM machine. I could put a .005 hole through a 1/4 carbide ball.

Now that may be bigger but harder to do ( ignition distributor and carb had to be made down sized)
