Air Drying the 9's (Three truck Shay) steam cylinders

[CGiordano464]

whta pressure that at? like 80

The gasoline twin screw compressor runs a bit over 100PSI, but I am not sure of the exact pressure. Consider that the boiler usually runs at 175PSI, the "low" pressure from the compressor works adequately for this task.

That's an absolutely fabulous Shay !! Ranks right up there with Cass No.5 shop number 1503, built 1905; 80 ton-3 truck. Are you familiar with her? It's my favorite. But MCRR #9 is pretty nice! I'm also glad to see that youall got the original number plate back! Excellent!! Right now I'm building a Live Steam 1 1/2" scale three truck Climax, but after that, I hope to build a 1 1/2" scale three truck Shay, most likely after Cass #5 (because I live closest to that Shay)
