Thanks for your interest in the Cricket. It has been an experiment for me. My initial efforts were to learn how an air hammer Air Circuit works, followed by building a small air hammer to apply that knowledge.
It's been quite a journey... Over a year of effort now.
I started posting to Facebook about it when I started working on the hammer in April (2017).
There was a fair amount of interest in the hammer because it is small and easy to build, so I decided to share what I learned.
I'm happy to answer any questions on Facebook, this forum or inquires sent through the Contact link.
