Twin Cylinder Oscillator

 

This is a little number put together from bits and pieces laying around the shop.  It is really a recreation of a photo I saw where I thought I could do it better and I think I achieved that.

This was an interesting project.  The valving is closer than any oscillator I have built before and I was afraid it would not work properly right up until I put air to it.  The cylinders are single acting, but it produced more power than I thought a single acting type would.  It runs at about 2000 RPM on 15 pounds of air pessure.  Although I usually prefer double acting pistons, I like it
