Air Powered Hit and Miss

[hhoult]

This is based on a set of drawings by Brian Rupnow. 10 years or so ago I made a couple of parts and then other things came up so they went in a box with the plans. In December I was looking for something in the shop and rediscovered it. I completed the remaining parts and voila.

If you watch the video you can tell I am not a cinematographer. The squeaking is from my air pressure regulator.

Thanks to Chuck Fellows and Brian for the design and drawings!

Looks great!
I built one of these a few years ago.
I have it hooked up to power my marble machine - it gets a lot of attention at the shows!

Thanks for the comments. My 6 year old grandson asked what do you use it for - the marble machine is a great idea.
