Steam locomotive BR52 Kriegslokomotive from scratch (1:25)

Hello



What is delayed is not lost. It is finally time for me to cut this steam engine. The project was created some time ago and was waiting for its turn

The steam locomotive together with the tender was developed on the basis of the original construction plans and I hope it will stay as faithfully as possible by me

mapped in a cardboard model enriched with laser cut elements and some 3D printed elements.

I do not know what but it will turn out in the wash.



It will be a long relationship for the patient



I start the construction from the tender as I have lasers for it. It is a tender with the German designation K4T32 on P.K.P. it was called 32D43



Technical data of the steam locomotive



Standardized DRG 52 series with a European standard gauge 1435 mm gauge

A few renderings to start with

At the beginning, the frames are reinforced with inserts, something like underlining in ships. As for beer cardboard, I recommend a better gray one. I had to replace it with a gray one because the inserts were bending due to stress. Reinforced with CA glue and primed and polished.

I also started to cut out small nuggets like cabinets and stiffening the coal box. The time will come for the veneer, let the skeleton rest, which would eliminate the collapse of the inserts.

and the frame of the waterbox of tender

Hello there,

I did not do much. I added the rounded parts of the tender tub, the coal chest

No door for now because I plan to open it to some way. Now I am starting to cut the frame with the clutch box and the endcarriage with the drawbar system of the hook at the rear of the tender. The whole is sprinkled with primer as the paint dries i will finnish with fine grain sandpaper and we fly on

Not much today. Part of the tender frame, namely metal sheets with a yoke under the bogies with friction inserts.

Today I made parts of the tender support, namely the front coupling box with the coupling pin bearing and the guides for the buffers. Bumper spring between the locomotive and the tender. Rear coupling box with bumper seats, hook guide and draw gear. I also embedded the water inlets with sieves and glued the supports for the carbon box. I also made an imitation of welds on the dividing line of the water box.

and another pictures

I haven't been here for a long time and I didn't throw in anything. There was not much time for gluing, but it's time to change something.

Brake cylinder and handbrake parts

Dors on coal box

Water level indicator, Desilter rod guide, power cables

Water inlet covers, toolbox doors and details

and tender main link pin and screw coupler

I also made a pair of valves, timing, distribution and fire protection.

and the wheels of the locomotive which are 3D printed driving and tied, and the front carriage full and tender

Hello, a few photos from the construction site

Compressed air tank, shut-off valve and dehydrator, I also made a few small parts such as piping hangers, tension spring. Now I'm starting to play with brake wires and heating part piping on the tender.

Small elements gathered together, so it's time to paint and stick to its place

Another struggles with parts

Quote from René Pinos

Hello Draccus,

This is wonderful scratch modelling.

Can you please explain the tool on picture 181729 which seems for me that it is not a simple drill.

Regards

René

Hi René Pinos, Philipp Tietz, Joon Kwon . Thanks for words of appreciation. This is precise hand drill with very small drill bits Ø 0.5 mm or even smaller. Something like this below

https://planszostrefa.pl/pl/p/…ure-and-Model-Drill/11030

I use the hand made tool which is a cut medical syringe needle to make small rivets with a diameter of 0.2 mm to 0.8 mm

Hello, the next struggle at the construction of the tender. I made some new elements like steps on the endcarriage, some brake lines and valves landed in their place. There is a handbrake crank, grease nipples and stiffeners at the door of the coal box. Two layers of target color also went.

next set of photos

Hello

Jan in first order i use to impregnate paper by special varnish called in Poland Drewnochron Capon Extra. This is used to impregnate wood. Paper then is simmilar to something like plastic. Then i use a primer MOTIP 1K PRIMER FILLER for cars in large spray. For pre shading use a coomon black matt from tamyia. Then a base colour darkgray (also MOTIP) in spray two or more layer depends how the cover looks. For weathering use some pigments from MIG they have a special sets for lokomotives an railway stock, also oil paints in a tube for painters like Rembrandt Oil colour

Other items in place Brake cylinder, valves, levers, heat pipe and lubrication elements. I also got ladders and brake hoses with valves. At the next stage of construction, there are bogies with the entire braking structure. Probably another update after the weekend

Hi all.

Thanks Christian

I slowly pick up the bogies and the whole small parts that is inside . Of course, I start with the frame, and while it dries up, I make the equipment.

The photos also show how it forms on a mouse pad and press the top sheet against the frame with a form to keep its shape.

Hello, another edition of work on the tender.

Axles, axles, wheels, gear levers brake and spring suspension seat

Hi Draccus,

I’m following your thread with great interest.

Thanks for sharing the detailed assembly steps, which gives me a lot of examples that I want to follow.
wonderful build.

Kudos !

Hello. Thanks for the words of appreciation. I've seen your works and the model you make will surely be elegant

Hello

Another struggle in the construction of the braking system. The next stage is hangers and brake pads. After assembling together with the system of tendons and triangles, the elements land in the frame.

My patent for painting rims. 0.5 mm cardboard box with a rivet hole. On the other side, it is held by pressing the cardboard against the surface. Then 2-3 coats of silver paint. Then, after drying, the contact surface with the rail is rubbed with a pencil with graphite powder obtained from the stylus. Part of the rust pigment and wreaths ready for installation.

Brake system elements on place

The next step is to put the axle boxes on the axles, fit the plugs and put them in the frame. One by one gluing axle locks, axle springs and that's it

Modeling work slowed down a bit. While waiting for the decals, I moved back to the drawing board. I am already getting ready to glue the steam locomotive, and thus I need to make files for the lasers and see if there is anything missing on the sheets and instructions.

I would almost forget adding the protective poles on the bogies,: oops: I also made a rag collar between the tender and the steam locomotive. To the next: bye:
