The door hinges are made according to photos I've made of a Klappdeckelwagen at 'Le Train 1900' preserved railway in Petange (Luxembourg). They have such a wagon, used as storage for firewood for their steam locos.
These hinges differ a bit from the ones I've seen in photographs on the internet, but they look very sturdy and that is for a 1:8 scale model, that will be really used on a railway, always a big plus.
These hinges differ in that way, that the door stops - that keep the door in the upright position once opened - are made of a plate, instead of a bent strip.
After bending a 1,5 mm steel plate at an angle of 90 degrees, it was clamped on a homemade fixture, and the outside contour was CNC milled.
The inside was done with a second program and a 4 mm end mill
6 left ones and 6 right ones.
The 'new' second-hand computer ( i3 processor) is doing the job without any problems.
Bending a small strip (5 mm wide) as support for the end stop.
Bending is done by hand in the vice. A guide was the hinge itself.
Once I got the hang of it, I was able to make 12 identical strips.
A corner strip was silver soldered against the hinge. It was kept in position during the soldering by some heavy magnets.
This method was also applied for soft soldering the support strips. (The magnet is retrieved from a defective hard drive of an old pc)
The complete hinge part for the door.
A pilot hole and retaining screw are used to set up the hinges on the door.
The other part of the hinge was also CNC milled from a 1,5 mm plate.
A small fixture, to keep the bottom plate and hinge in position during soldering.
The two brass blocks ad some weight, to keep it in position when heated.
Mass production? Only twelve are needed, and they were made in only two evenings in the workshop.
A first test fitting on the wagon.
Everything fits and rotates as designed as in Solidworks.
The outside lids can only be opened after the middle one is opened first. This is as on the real wagon and due to the rain gutters.
The hinge is riveted to the door with 2 mm brass rivets.
The steel wheel casting has arrived from Brno ( Czech Republic) and looks very nice!
Render of the Klappdeckelwagen in Solidworks. As you see there is still a lot to do to make for the model.
The total length of the train set will become about 4.15 meters.
