The first time I try to build the motor using machine tools.
The cylinder diameter 20mm
The piston stroke length 20mm
The compression ratio 6.
Air Cooling.
Splash lubrication oil poured into the crankcase.
Unfortunately we have in Russia is difficult to find for sale spark with thread...
I also wanted to make the motor of the compressor, but found only a small compressor of the refrigerator.
It is made without tools, but you can see that it works

It's very interesting what the outcome...
This is my first home-made engine, it is made from the compressor of the refrigerator. Its volume is 11 cubic centimeters.
When it was built were not used machines.
Here's a video of his work.
