It is such an awsone work that you are allowed to write all the commentaries in English if you wish. We will translate them.

Thats cool!
I feel a bit uncomfortable using google translate, as I have no control over what I am actually writing.
So a little more on the project.
The prototype for this wagon were built in 1908 for the Thamshavn Railway here in the middle of Norway. It was used for hauling copper ore from the mines at Løkken to the port at Thamshavn.
My model is 1/45 scale, 22,22mm gauge.
The underframe is entirely made from 0,25mm nickel silver etchings. The etchings were made by PPD ltd in Scotland, and I can really recommend their service.

I use brass rivets for as many connections as possible, this helps a lot when soldering the parts.
For solder I use Berafix 60/40 tin/lead soldering Cream that has ZinkCloride added as flux. I use a London Road Models Resistance soldering unit, and I can really recommend this combination!

The wheelsets have a fine scale profile, and they were custom-made by the very talented danish modeler Erik Olsen.
There are several interesting articles on his techniques on his homepage:

The brass castings started as a digital 3D-model made in Solidworks. A wax print was then made on a Solidscape printer by Precision Wax in the UK.

The actual casting was done by Dave Sciacca of Valley Brass & Bronze. He made a RTV rubber mould directly from the wax master. This is quite unconventional, usually a intermediate metal master is lost wax casted from the wax print, and then the rubber mould is made. But Dave knows his craft, so the castings are superb.

Several 3D-printing and casting companies rejected the job as they found the cross-section too thin (just 0,4mm thick).
Both Precision wax and Dave Sciacca put a lot of extra effort into making the castings, and they have my best recommendations.
The brass parts are blackened with Casey Birchwood Brass Blackening.
The wood parts shown in the pictures are just test pieces. I used plain Kappler basswood stripwood, and milled tongues and grooves using a desktop CNC router/mill. I did it with the milling machine stationary, and draggged the stripped pass the milling bit through a slot milled into a piece of Corian with a brass gate across the gap.
Hope to post more progress photos soon!
