I have moved my modelling chamber into the basement now,
as such, work will be easier and the background rather constant and not all over the house as it used to be. It is still basic compared to many mancave pictures I have seen, but it is good enough for me.

The laid tracks would be the length of the engine. While thinking about the dio and the arrangements, I have continued work on some vehicles which will go along with it for sure.
The HL42 TRM for the Waffentrager is getting closer to completion and I have begun spraying the hull partially with primer.


Turns out, it needs some fixing before continuing.


Have a good day, comments and ideas as always welcome.
Prost

Nice progress as usual. I don't know if you use them in Germany but here we have a lot of air powered tools like nail guns and socket wrenches. I bought an inexpensive compressor from the big hardware store. It works great. I think anything from the hobby world is always more expensive.

D'day,
Still looking for compressor info if anyone with ideas is going through the trouble and reading this.
Just a tiny bit of progress, some more parts were added and I continued adding paint to the front of the frame.

Have a good one. What do you think?

Good day together,

I have become to realise now need to buy an air pressure thing for a spray gun/airbrush, as I have none. Any Compressor or Airbrush suggestions?
As there will be engines to follow and tanks to be added to the diorama, brush painting it all will probably not be possible and would not lead to good results?!!?
Any ideas or help would be appreciated.
Cheers,
/Stefan

Kenneth, that's what forums are for I guess. I read up most of this in books in the recent two years and a friend on milmod taught me a lot! Glad you like it.
Tim, welcome. I just ordered acnew book about steam technology ^^, more to come.

Stefan thanks & great tutorial, now I get it! And it explains something I almost hadn’t realized I’d noticed with real locos, the rush coming out of the funnel doesn’t always look like just smoke.

Tim,


Smoke (green lines) comes from the fire box via the thick diameter smoke pipes and the flues (the small heat pipes of which there are much more). Within the smoke pipes are the superheater pipes. Water runs through here to get exposed to the hot smoke (after being heated already in the boiler and the steam is thus heated again). The superheater "dries" the steam and makes it much hotter and faster. These are the many red lines. After exiting the superheater, (4 pipes run towards each cylinder collector) the superheated steam is then directed towards the cylinder via the pipes on the left and the right. See the red lines below:

After the steam is used in the cylinders, some of it is used to power the blast pipe which shoots out of the funnel/chimney on top in the center (red-blue line of the used steam). This draws more smoke from the fire box and keeps the fire running as it is creating a constant air flow. The fire itself draws air from around and through the ash pan air intakes.
The sparks and ash that are sucked into the smoke box are stopped by the spark arrestor and are collected on the bottom (yellow stuff) once the train is standing safe (away from wooden tracks). Often the floor is covered in clay and stuff, in order to prevent structural damage to the floor, afaik.
Here another drawing, thiis shows the steam being sucked into the superheater through the right side pipes into each smoke pipe (purple), while the superheated steam (red again) is coming back out towards the left pipe and is then directed to the cylinders.

As such, there will not be smoke or ash debris or anything in the water pipes, other than what is in the water (if bad water was used and not treated right).

Hth,

Happy Easter to you too Stefan

Mmm detecting the whiff of coal dust already. I’m not that familiar with loco engineering so these may be a dumb questions, but (a) this is the funnel right? (b) and if so presumably the smaller pipes around the arrestor clogged with accreted ash deposit if not cleaned – what were the smaller pipes for? (c) From what I can see the smoke passes along the big pipe and through the arrestor, the sparks are trapped or continue through while the smoke comes up through the mesh? (d) What happens to the ash after it’s passed through the arrestor to the other side of the big pipe?

Good day together,

I have noticed that I forgot to share some interesting information which I should share with the ones interested in BR52s. The original technical drawings and early photographs from 1943 show the spark arrestor as a cylinder, as can be seen below.

*1)
However, as some of you might have noticed, mine is cone shaped:

This is the case, as of on July 29th, 1943, the "Arbeitsausschuss Reichsbahn" was briefed by Friedrich Witte that the cylinder shape did not allow for proper cleaning of the pipes and the more complex cone shaped spark arrestors are to be implemented and produced again. *2)
Just in case anyone wondered or was thinking why my build differs from drawings with this respect.
In the meantime, I have begun priming the thing... At least parts of the front frame structure, it does need a lot more attention and more painting though.


Have a great weekend all.
/Stefan

*2) see Eisenbahnjournal II/96 - "Die Baureihe 52" page 19

Tim,
None cares about the underside^^, well usually at least. I already put too many parts together, painting it now is hell (started yesterday).

As to that piston rod, I am not sure, have not looked into the piston plans and technical drawings yet, as their construction is still far away at this stage.It is invisible for humans (only spiders crawling underneath would notice it if it were wrong)
I need to build the ICM railway Panzerspähwagen now.

Ahem gulp little did I realise my crap underside painting would go on show…but as Stefan says the point is to compare Trumpy’s oob with the staggering mods/corrections he’s doing.

He’s far too modest, I just think that those who are interested – and there seem to be a lot – should be able to better appreciate this project. I found this kit one of the more challenging I’ve built - and it is a great kit if you want a decent-looking train like I did - but it just boggles me how far he’s going to upgrade it.

Er Stefan I think in the engine photo I’ve been further exposed – those rod thingies coming forward from the piston housings…there’s a rectangular hole in them…have I put them on upside down or something?

Kenneth, thought so, too, but there are always smart folks out there who might know just more and have better ideas, and I will gladly listen.

Tim, aka Dioramartin and I are currently taking photos from similar angles and points of view in order to compare the OOB version with the modified one.
Tim has suggested that we do so and as such, we will try to organise and do a few comparative shots every here and there.
Tim, many thanks, in the end, it might help some modellers to decide whether it is worth it for them or useful to do some modifications or to just leave it as it is.
We thought of it kind of like below (at least that is how I understood Tim).

The kit tender floor, i.e. Tim's great work:

Hi Stefan,your idea for a diorama seem plausible to me,who is to say where certain units were exactly, during the chaos of the last few weeks of the war.

Kenneth, will see how the next steps will go on, more new parts have been made yesterday.
Cheers Jerry.

I have an intriguing question regarding the design and planning for my diorama...as I want to start planning and building the engine shed and surroundings...

A Sd.Kfz 251 pioneer bridge Version... sitting beside the train together with my Waffentraeger Ardelt (1 of the six Ardelt ones produced)...
I mean this one:

Is that plausible or utter nonsense? (February 20th 1945 in Eberswalde as the Waffentraeger were in the city that day) And maybe the Panhard 178, i.e. "Panzerspaehwagen 204 (f) Schienenpanzer" the German captured Panhard of which 43 were converted to railway recon vehicles for the East...

Thanks for ideas, criticism, suggestions and or help.
A quick n dirty test fit before the end.

Jonathan,
They are a pain^^. And quite a few more are needed. I need to order more styrene and profiles of all kinds, I ran out of most

A lot of sanding is needed and more detailing, but I think I will paint it tonight before continuing. This was before major changes were added and parts reshaped:


This is the bolt that will connect the leading axle to the first powered axle. It is a 2mm rod, on top of which is a .8mm thick disc (2.5mm diameter) which I cut into a hexagon and on top of it is a tiny disc of 1.5mm in diameter. The side I am holding will be within a boxed casing attached to the first powered axle (from the front).


The next step was an annoying part as much plastic had to be cut away at the bottom (second picture) then some plastic card had to be added to the top and then the sides had to be reshaped to come up for the curvature (the centre of the cross section was thinner than the outside - see my nasty drawings on the second picture). Also a few cuts were needed to cut away the recess where the rims of the vertical support join the horizontal support beams. (the four circles show this: on the bottom is the stock kit, on top is the modified version.)


Maybe this drawing helps to show what I am trying to explain... This also shows what had to be cut away at the bottom (blue markings). The kit part has the bottom enclosed, however, it is open with the real engine:

Compare the steering rack and additions:

1)


2)

Notice however that both shown driving racks are of different shapes and both are no original ones and do differ slightly! But they do help depict the general shape and problems.

The advanced and further modified steering rack laying on the boiler support.


In the meantime, I added the screw mechanism for the leaf spring pre-tension torsion bars.

The top has been modified towards the front with the guiding support T-section in the front.


Finally with wheels in place to have an alignment check. The top of the steering rack needs to be just below the second swing within the frame and slightly above the very bottom of the frame. If this is misaligned, the leading wheels will hang loose in the air and as such this is a difficult part as all parts need to be assembled and painted and then put together, and only then will I know if it worked (as all will be moving parts and I will not glue them)


If I screw it up, I will glue it down in the worst case^^

Have a great evening, hope you like it and I am not boring anyone.

Jarry, thanks.
The Ratte blog is my favourite, the guy building the 1:35 Ratte is totally amazing.

I had a few things which I forgot to add. Additionally some new lower frame plating has been cut for the rear of the boiler support. Many more lower frame parts are yet to be added, but I think I need to clean, sand, prepare and paint the interior first.


There are so many holes and sparrings, no clue how to paint all this... Maybe I need to start priming and preparing it now before assembly, especially now that the drive shaft springs have been added below:


It needs some trimming and sanding and the top got broken so needs to be done anew but it does help with the impression, even though it is not even aligned properly^^. Actually what is on top now, will later be the bottom side of it, the front is to the right. It does differ substantially from the kit now.


Seen from the top it will be about in this place below the whole frame.



The single hole in the rear of the boiler support will be bolted to the centre of the leaf springs and it will be able to "swing freely" (it was anyways in the real engine). The spring connection rods are not perfectly aligned, they are bent a bit, so I will drill a different hole and align them again and thereafter I will cut the slag off the edges of the rods as they are yet too long.


Still so much more to do, but at least some progress. Have a good evening. I enjoy building this thing, the plans and original designs I found are quite nice and I am getting along better with all the styrene by now. As this and the Waffentrager are my first scratch attempts, I feel I am getting used to this and I hope it will pay off in the end.
Cheers all,
Prost,
/Stefan

I am still following along and still think this is one of the best builds ever on this website. Scratchbuilding is model building in its' purest form. You are really doing a fantastic job bringing the cold hard 2-D drawings to life.
