Your stack base is a wonderful work-around. And, once figured out, it's wonderfully simple. Your finished piece looks great! Thanks for sharing your experience.

The loco now has a face. Smoke box door is riveted to the hinges, the front skirt is attached and the buffer/buffer beam mounted. This buffer beam is L-shaped and bent forward, no idea why they did this. This is the current look:




The rear buffer/buffer beam is also mounted. Currently I am working on the cab:




The outline of cab and skirt parts have been cut on Dennis' CNC mill, the rivets marked on the back side with a center drill also under CNC control and then punched with a NWSL punch/die. The rear wall of the cab needs to be bent and then it can be soldered.

Henner,
this is a work of art, Beautiful Craftsmanship! And yes please do tell how you machined the smokebox door.
Thanks for the kind words (Llyn, Bill, Poys and Scott). I start with a brass disk of oversize diameter/thickness and soft solder it to a brass bar. In the next step I turn it down to the correct diameter and length (thickness). I then use an Excel table, indexed by 0.002" (0.05mm) in x and start turning from the outside to a diameter (or travel) given by the table. Due to the setting of the x-axis you don't get lost in the table. Each cut only removes 0.002". You get very fine steps, which can be easily filed/sanded.This is how it looks like after turning:


Normally I use my radius attachment from Sherline for such an operation, but in this case the radius was far too big. Hope this helps.
This also works for a parabolic nose of a streamliner.

It's been a while since I posted something on this forum. Well, last year I relocated back to my native Germany - getting older and wanting to be closer to family. It took some time to get my workshop back up running. But now everything is in place and I even purchased a nice CNC mill, small but very precise. My cog loco now has complete water/coal bunkers with lids, beads around the cab doors (sliced copper tubing courtesy of Bill Allen) and finally a fairly complicated dome:


The dome conceals a Goodall type feed valve and a doughnut shaped manifold to route the steam pipe around the filler valve. A screw-on cap keeps everything in place.

Looks awesome Henner
I especially like the way the steam pipe goes through the dome and then goes around the Goodall valve all inside the small confines of the dome

Thanks guys for the kind words. In fact, we already video taped a test run on my Fremont/CA layout (Posted here on June 15th 2019), climbing a 30% grade.
About the boiler: It is a very simple design like a Ruby and yes, I have drawings.How to send them, as I don't see a an E-mail capability?
Regards
