Thanks for the warm welcome!
This project started out as little more than an experiment. Learning new skills, pushing my self out of my comfort zone.
I actually did not expect to be able to build it! Hence, no progress photos...
After a lot of trial and error on the spoke wheels, I was almost at the point of giving up.
When I finally 'cracked the code', finding the right material for the spokes, setting up a 'pipeline' for building the many wheels and tires (the tender has 8 wheels and tires - trailer 4 of a different kind) the rest of the build went smoothly.
This is a photo of some of the 'parts' of the build.

But I am considering, building another one, documenting the steps of the build.
