Hello friends,
We had a great weekend at Dresden :D . For the curves of the layout were a little tight for my A, I had it steaming on a roller board. Much better for the interested visitors to see her life directly in front of their eyes 8) instead down on the floor (so I think).
We had her working there at both low speed and full throttle with working stoker :wink: . You can imagine the cinders thrown out off the double stack! The Y6b of steamchris was coupled to the tender but not under steam due to the lack of a second roller board.
All the best by

Hey Steamers,

yes the exhibition at Dresden was Fun.
We also had the J runing with Air and our Y6b and our narrow gauge Loco on display, on the tracks we moved our freelance 0-4-0. Here a video

Hello friends,

After spending almost a year to paint my old DB class 44 and bring it back to life, I started finishing my A again :D .
First project are the two Westinghouse CC air pumps.
The cylinders were sand casted of bronze. The mold included a shaft which made centering in the lathe quite easy :idea: . The the LP bore of diameter 35 mm and the front side were turned first. Then a shaft of precise fit is used for both turning the back side and milling the HP bore of 22 mm. All threads will be bored on the turntable, too.
Just 2 steam passages will be bored into the cylinder body. All the rest can be bored into the upper cyl. cover.
Thus there will be not flat (paper or ptfe) sealings, just 2 O-rings between cylinder and upper cover :idea: .
To be continued!

Very much looking forward to seeing how the CC pumps turn out. Look great so far. Please provide as much detail as you are willing!
