You can view the first revolutions of the functional prototype. It does not have an adjustable journal. I had it built last summer when I was not sure if I would get a patent and did not really want to reveal the details of the journal adjustment or have an adjustable journal prototype built.
It was running on the air in a small pancake compressor without the compressor itself running.
Going to run it on some shop air tomorrow which is about 130 PSI with an 80 gallon tank. It should get to close to 1500 plus RPM then.
The voice is my son in law.
