A couple years back, I got a Cary lead S-2/S-4 body, and made a nice custom chassis for it using a coreless motor with a gear head, a chain drive, and bevel gear system to power all the axles. It runs very nicely!

That sat around for a while, and now I've finally gotten around to detailing and painting it!
The only details I added that weren't included were the grab irons. I also wired in directional lights. As for the paint, I went with PRR because it's easy!

An amazing restoration of a vintage piece. Did I read that right, a lead shell?? Nifty little layout,
on the video. I have come to believe it takes a great deal of determination and focus to stay small
and stick to a theme (I seem to lack either). I'd like to see her going about the layout in her new
paint, over that crossover.

Awesome restoration work!! The painting and decaling craftsmanship looks exactly like it was manufactured that way!

That engine looks great. I like that Brunswick Green, anyhow and the yellow handrails set it off. What's more impressive, though, is the mechanism. It really does run smoothly and I imagine it took quite a bit of patience and skill to get all those pieces to play nice with each other.
Those bevel gears are interesting. There's a lot of geometry involved in getting bevel gears to mesh when the shaft passes over the axle rather than stopping at it. The teeth kind of spiral down the bevel in a kind of helical pattern. Presumably, the exact clearance between the shaft and axle matter to the geometry of the gears. Do the black sleeves on the axle just inboard of the gears also go around the shaft to maintain that spacing?

Chops124, thanks! The shell was actually new in the box even though it's likely about 40 years old now. The main casting is lead, the pilots, exhaust stack, and the back of the cab are white metal, and the roof and handrails are brass. You'd think lead would be easy to drill for grab irons, but it's so soft that it actually shapes itself around the drill bit and grabs it if you go too fast!
RP model railroads, it's amazing what quality paint and decals can do for a model! I used Scalecoat II for the main color, and the Microscale decals are so thin that once you put on the clear coat, they really do look like part of the paint.
Barry, thanks, but who's Robert?
scsshaggy, it did take a lot of patience to get the chassis just right! I found the chain works better if it's slightly loose instead of tight like a belt, and every part of the bevel gear mechanism had to be made to an exact length to work right. The plastic cross-boxes were included with the gears, and they help to maintain an exact mesh. The gears will go out of mesh and slip with the slightest movement, so I soldered the outer truck frames together with everything already in place to make sure they were really solid. If I make a chassis like this again, I think I'll just use Hobbytown helical gears now that they're back in business. Getting those lined up is a lot easier than working with bevel gears.
