We had our BAGRS annual meeting yesterday and I took her down to display on our tables. I had the engine , tender, baggage car and two coaches lit up. I was going to bring my camera but forgot, but it looked nice and took up 2-1/2 tables to display

Here is a shot I took on friday to make sure the lines matched up


And one this morning after I wired the lights up


I have her apart and will be doing valve gear, steam and lube lines and RC this week so probably no more photos till next week

Forgot the camera...just more opportunities as the finishing touches are put into place. The train is getting to be well known to many with the "show and tell" opportunities you have had.
How did the drivers work out?
Good to "see" that the shop is up and running.

The numbers are at the foundry.

Thanks
The drivers worked great. The axle and crank holes were perfectly centered and everything worked freely with no adjustments needed. With the ball bearing journals, there is no clearance as in bushings so everything has to be within .001 to work right with Dennis doing the CNC on the frame and axle boxes and Justin doing the wheel machining my part of that job was a snap.

one thing that was challenging was that as the fairing was to scale and the prototype ran on large radii, the cylinders had to be closer together than we usually do to fit inside the fairing. This made for the crossheads and rods to be closer to the frame and with less clearance than usual but I ran the chassis around my 9.5' radius track with no interference and it actually may be able to negotiate the 7.5' track though the clearances are much tighter there.

Glad the drivers, cylinders, pilot and fairing work out to allow for clearance on your track. Appreciate the updates and your photos so that we can follow the progress.

Well, I got the valve gear and such done this week and was able to air test it. It does run like a dream. I was able to skim the paint off the tread and flanges while running it on air.

Here are the steam lines which will go into the smoke box. the front one is the exhaust and the rear is the steam line. The small tube going back is for the lubricator.


The axle pump tubes are run back.


The ball bearings are installed in the valve frame for the expansion links. Each link will have two bearings stacked together for rigidity and long life.


The reverse servo is positioned between the frames and will be accessible from under the loco


Here is the valve gear. The piston is in the rearmost position and is ready to come forward. The combination lever is at a sharp angle which is moving the valve forward to open it at just before rear center.


now the piston is in mid travel and the eccentric crank on the wheel has taken over the work and the combination lever is now vertical causing no effect on the valve.


here is a close up of the lubricator adjuster. The tube comes up through the center of the lubricator and the fitting soldered on the end is finished off with a tapered edge which will seat in the nut to close the steam off. When the nut is backed off with a 2-56 nut driver (1/8"), the steam flows out the hole in the side of the nut.


Here is the complete assembly




And a closeup of the valve gear

Last Saturday Bill brought his chassis over to our weekly workshop and we ran it on air. My compressor is tiny (used for spray painting) but as the cylinders were virtually leak-free it did not have any problems running the chassis. Here he is seen scraping the paint off the wheel rims with Dennis looking on:
