Mike, in spite of your “inefficient” comment, I for one admire your production speed! In addition, sharing your work is inspiring me to restart my 3D modeling learning curve.

I'm 3d modeling an interior for brass cabins, and attempting to fit space for electronics, in the process. That's where Jim the electronics guru comes in. We hope to create a well-hidden, track-powered electronics package that provides smooth, constant LED interior lighting. The goal is for the LEDs to stay lit for as long as possible; perhaps 15-30 minutes. I also need to thank Ken Miller for a floorplan blueprint, and Matt Goodman & Abe Burnett for their support, advice, and reference pictures.

I am debating the value of adding cross walls behind the cupola seats on which I can mount the air brake valve and air brake gauge. I'm not sure how visible they will be when added, which will determine my interest.  I also need to add handrails up into the cupola from below, as well as the handrail that was mounted near the ceiling and ran lengthwise in the car for holding one when climbing down. This is where Abe hit his head often in the dark, and I posit this may be the cause of his talking about turnips in so many emails.

You can see below that they used a ton of solder when assembling the car. Even my desoldering copper wick couldn't get it all cleaned up very well, so I just ground it out with a tungsten carbide carving bit in my Dremel. The solder comes away quickly and it's easy to stop at the brass. I did overheat one corner of the car while grinding away blobs of solder in the interior corners and the corner came de-soldered. I will have to be aware of this on future cars and remember to use a damp towel to keep the car cool when grinding.

> The interior on the left is before Abe told me he never saw a cab in this configuration (hey, I built it to the blueprints Ken Miller sent me!) Turns out the blueprints we started with were for pre-1924 cars, so there went another evening of modifications. There are not yet lanterns modeled. there were two kerosene lanterns; one over the sink and one on the opposite end of the cab, on the opposite car side, but it was attached to the cupola seat wall, not the cabin outer wall.

I did complete the car side last year, and decided I would prefer to make a complete car rather than attach a car side to an inaccurate donor core. I sort of stopped because I wasn't sure how to model the complex curves of the roof ends, but that has been resolved. If you can be patient, maybe I can knock it out after I finish my major caboose project. (painting and detailing a bunch of brass CF/CH/C3 cabins)
