The Pneumatic News

Thanks again to our ABBC, or Air Brake Bureau Chief, Brian LaKemper, who sends along a report of this past weekend's activities in the land of pneumatics.


This weekend was more of the same in several ways.
A fourth S-16 Governor finished assembly, and I started assembling a fifth. This is the line of governors ready to set pressures and test. The one most recently completed is destined for CA&E 451.
This is where I got assembling the fifth S-16. I can't install the piston yet, as it's ring is currently stuck. This one, and the piston from the sixth S-16 will both need their piston rings freed before they can be completed. 

I didn't take photos but I finished converting the base for the fifth S-16 to an S-16C by threading the previously blanked hole for a spitter fitting. This governor is ultimately intended to be installed in our other running curve-sider, CA&E 460.

I started taking apart the seventh S-16 (this batch will total nine). I neglected to get photos, but it looked more or less like the others that have been taken apart so far.
Will finished rebuilding a Christensen straight air valve for CSL 144 and that was installed. We took the old valve from 144 and opened it, shown here. We'll get this one cleaned up and on the shelf ready for use again. I forgot to get a photo of the new valve installed in 144.
I also swapped tips on some of the finger bases for the S-16s that are still in the queue for assembly, here is a worn one next to a new one.
