If there was real interest producing new cylinder castings would be an easy fix... wheels too.

Do you have a complete drawing set for the engine?

X2 This is the first thing that I would check into.

Looks freelance to me, also- boiler built out of brass? That's no good.

Fantastic work!

It sounds like your pattern/casting may be more complex than some of us are imagining. As mentioned above, I would add shrinkage uniformly to the pattern as a starting point, if everything works out OK you will have a usable casting. That being said; the volume/mass of a part has an effect on how th...

The tender looks "ride-able" scale (3/4" or 1" ?)but the two engines look more like Gauge 1-ish to me. They do not seem stout enough to pull someone.

It will be great to have this all recorded somewhere!

When I selected 3D CAD software I was put off by Fusion 360 not being on my own computer. Not being able to get it to operate on my computer sealed the deal and I went with Freecad. Does Fusion 360 support 2D CAD as well as 3D? NanoCad looks interesting, but I'm a bit reluctant to put Russian softw...
