Ooh Ahh! Excellent work!
WIP. A 2-cylinder engine for a paddle steamer. Still a lot of parts to make.
Good stuff Dave, as usual. Out of interest, where do you get the reference material?
Thank you.
I don’t know. It just comes from going down rabbit holes on the web.
Double shadows. Is that from Environment plus original style shadows or superimposed in post?
Actually both shadows are environment shadows combined in the image editor along with an edges-only export. These are the two shadow images I used. Some soften/blurring was applied to the shadow images in the image editor.
Here’s a detail of one of the paddle wheels for this recent engine.
The paddles are articulated so their angle changes as the wheel turns.
Screwing around with it a little bit.

Still need to time the valves and put the eccentric straps on the eccentrics as well as add the screws and stuff. Render is basically straight out of SketchUp. Metals from the 3D Warehouse, the red and green are from the livery colors for the old LNER (London and North Eastern Railway).
PLA or ABS? They look great!
Thanks. These are PETG because it was already loaded.
FWIW, adjusting the CofG involves moving the Camber Mount Clamp (CMC) on the seat tube. If one wants to move the CofG rearward by 6mm you put one of the 3D printed clamps on each side forward of the CMCs using a 6mm-thick gauge block to space them. Then loosen the Allen screws and move the CMCs up to the 3D printed clamps. This ensures both CMCs get moved exactly the same distance.
Gotta love some 3D printing.
Another little engine. The flywheels are 100mm dia.
Will never get tired of seeing these mechanical marvels that you model. Definitely have a high level of cool ! 
Thank you very kindly sir.
