Hi all,
Minor progress with the frame and all the rivets, the first few hundred are there now.
I have begun adding the rivets to the rear of the first batch of rivets and have finished adding the rivets to the top of the frame support along with a few hex bolts.

The top of the frame is almost done. It needs some more 1.2mm hex bolts and nuts, but all rivets are in place now.

I am waiting for the resupply from MasterClub, as I will run out of the 1.2mm rivets soon^^.

Hope you like it, have a good weekend modelling. The weather is awful here, so there should be some bench time tomorrow.

Tim,
Butler would be the surname. I encouraged him to post it here.
The orange light inside the firebox does actually flicker and looks amazing.

Well, it’s as good as I manage to do it. There are better scratch builders out there, but it’s a fun thing to do this.
Have a good day.

Superb BR52 by Steve (surname) & great lighting (is there an orange one in the firebox too?) - yours is coming along great & I bow to your accurate drilling powers, you make it look easy but it’s the opposite

Hi together,

While doing some further research regarding the rear and the ahs pan, I have done some work on the rivets and addedand glued in place the first 100 in total. But furst, some more alignment checks once the interior cross sections were attached to one another.


It's all square and fitting, so ready for the first rivets.


These are all MasterClub's 1.2mm sperical rivets (.8mm socket)


It looks like a porcupine before trimming all the excess material.
[/url]

The porcupine got cut and just to see how it looks like... The view from above, if the frame was ready... The vertical and horizontal supports are connected with 1.2mm hex bolts from above and hex nuts from below.

[/url]



More will be added tonight.

Good day folks,

I have to share this amazing BR52 of a fellow modeler on another forum. Steve’s 52 is one of the best, if not the best I have seen so far.
Enjoy his work! He has added lights and stuff and it is not yet finessed (as can be seen with the wrong dry-fitting placement of the driving gear)

Hi all,
For the fun of it, as I was adding some parts to other models just along the way, I thought I'd put it all in perspective. The locomotive is quite big compared to trucks, tanks and rail cars^^.

The Sd.Kfz. 251 looks so tiny next to it all.


Cheers,
have a good Sunday.

This build only gets better and better. Stunned by the amount of work you put into this.



Thanks there, hopefully it will keep improving. It’s been extremely educative and was a lot of fun with all the research and museum visits,

Hmm true, no worries, I am not adding all in the interior, that would be another 1k or so 😂. But still, trying to get it kind of ok n real. I have learned so much along the way, so all is good . Thanks man.

Stef - I know exactly how you feel from my comparatively simple trams, there does come a point when obsessional accuracy must give way to pragmatism. It comes down to the question why we do this – to provide a representation of the real thing as accurately as skills/materials/time allows. However if there is no outward visual difference whether a nut actually has its bolt going through a panel or not, there are times when the nut should be just glued onto the panel. I know, I know, that’s heresy when you’ve done such amazing research and work on it but I think the tipping point comes when enjoyment (and the structure!) starts to fail & it ceases to be fun. Sometimes one has to bend the rules – I think your audience will be just as blown away knowing (say) 1,000 bolts run through the plates & they never need to know another (say) 200 were simulated.

On that subject I was wondering before at what point the structural integrity of heavily drilled plates gets compromised, I guess there must be some formulae for grades of steel (and plastic) where you mustn’t drill out more than x % of a given area/thickness, taking into account what pressure/weight will be acting on it. There must come a point where fatigue cracks start joining the holes together, and I’d imagine plastic has a quicker failure point (scaled equivalent) than steel so maybe your choice of materials is going to make that pragmatic decision for you!

Did I mention it's looking fantastic?

Cheers Tim,
I will be spraying it, once I get anywhere near it, but this will take some time. I am almost done preparing the two frame sides and the interior support structure.
Ohne Titel by Stefan, auf Flickr

This took much longer than I have anticipated (also cause a few beers interrupted the process), but I have 650 holes drilled in the two frame sides as of now (and way more in all the supporting structure) and shortened about 1400 rivets and bolts. I can't add them in full length as I did in the photo below for the dry fitting, as I need to add the bolts from both sides and as such, all need to be cut to approx .3 to .5mm length, to fit into the frame, but not all the way through it. I have dry fitted the first part and added some bolts just to see if it was matching...

The above ones are the first 6 1,2mm hex bolts holding some interior frame support structure. There are so many connections and pars and such, I don't actually know how to go on from here. Way beyond my skill and knowledge level, now that I look at it, I should have simply built the kit and be done with it. Maybe I will glue it all in place on one side and then add all bolts n rivets before going on?

The frame resembles Swiss cheese by now and there are still about 30 holes per side to be drilled and added^^ (325 so far per side), most of them .8mm for the bigger (1.0 and 1,2mm), some .6mm for the smaller rivets and hex bolts (.8mm).




I used a basic rig (actually 3 of them, due to wear and tear) to get the 8 axle support structures (2* 2 rear and 2*2front axle sets) ready for bolting. The center ones needed a different rig, as they do have a few more bolts and the dimensions are different, the journal box cut out is a bit taller and wider here.

As can be seen, all of the interior support plates do still need some rigidity updates and some L frame addition for additional strength. The photo also shows some of the various bolt and rivet kinds used and deeded.

Now I am off wondering how to got on... and I don't know how.

Have a good one,
Stefan

Great work & scary complexity - what’s the game-plan for painting it - brush and/or airbrush?

HHB,
you have hosted all those pics on prime-portal haven't you?
I can't thank you enough for that! You got me hooked into all this with your albums, finally I can say thank you to you! Dankeschön:)

No, sadly I have not watched that series yet, was busy these last months... But I read about it, it received a few prizes and was in the FAZ quite often.

As to the moving of a wagon:
Maybe via truck after being shipped via cargo rail...? I have seen many tenders shipped via cargo rails. Then changing the trucks is not that difficult as there are tons of Wannentender trucks available for Regelspur. Hohenzollernbahn did this, and I think that the 52 6106's tender was also moved via rail wagon.

Cheers,
Stefan

Hi Stef,
I presume you watched Babylon Berlin? O.K. the BEM BR 52 is totally wrong for the time. But what about the Kesselwagen? Would they fit the late 1920 period? Still wonder how they brought the train over from Soviet Union without changing the Breitspur to Regelspur?

Good day,

I had a little styrene party with lots of thinner fumes as I had to rub and clean off all the scotch tape residue in my little cave... But for the first time since like 2016, the frame parts are now separated (see further down)!

To get the bolts for the frame ready, I have added and adjusted the journal box supports. The interior ones are 2.4*2.1 and as thick as the frame itself and 10 of them are needed. Without them, the sheet metal would tear due to the pressure and the indentations due to the cut outs for the axles (weakening the frame structure).

Drawn and scriped, let's get them.
Ohne Titel by Stefan, auf Flickr

All internal frame supports need to fit in between... So far all is fitting and I guess I cut correctly^^.


Exterior and interior supports, the exterior ones are far thinner.
[/url]

Cutting them into this basic shape (using the 52 6666 as an example:




Or the 52 8173-9 from below:


Once I adjust them into place and round them all up, they should be fine.



So in the end, they should all look like this, they yet need the support beams and the holes for the bolts. It is quite tricky now, doing all thinks on two different frame parts and paying attention to interior/exterior sides. I have also glued in place the exterior support bracket for the front most driving axle. Its needed in addition as the boiler support and cylinders are just in front of it.


I=Inside *O= outside I= inside the round circle below the axle cut out shows where the bars will attack that go from left to right in order to hold the journal boxes in place. To sow this I added a random piece of junk styrene to the Outside one (top).


You can spot the said bar here, with one of the two bolts (per side) visible to the right.:

I wish I had taken more photos when I was in Berlin.




Time to cut all these guys...


This is where we are at now. I have placed thick styrene to support the frame and to prevent it from bending. As it is heavy, thick and long, it tends to bends quickly and if it bends, I am in trouble.




Will see what I will get done today, the coffee machine is ready and loaded.

Prost,
/Stefan

Finally some progress.
Dry-fitting the first three of more than 1k bolts.


Drilling and bolting has begun.I have drilled the first 120+ frame holes. The frame consists of mostly bolt heads outside + nuts inside (sometimes reversed however), therefore for each hole=2 bolts/nuts-240/side i.e. 440 in total for both frame sides that could be added now. However, it is not that easy, as more symmetrical stuff needs to be drilled first.
I glued both frame parts together with scotch tape and as such it looks ugly and filthy^^. As soon as the last holes are drilled, I will remove the scotch tape, clean the parts and then smooth it all and add the bolts n nuts. Sizes vary between .6 and 1.4mm, but most are 1.2mm. I am using MasterClub products, easy to source and superb quality.



I have the amount of holes marked on this list and on the respective parts... quite a few more are missing.



A look at the basic frame parts and how much more drilling is needed to align all parts.



/Stefan

FYI, I have been invited to BW Berlin-Schöneweide and could roam around their steam locomotives.

Thanks again.

Just got a an invite to inspect the 52 6666 including the tender (Steifrahmentender) in its intirety....
So I can take photos from within and underneath the locomotive and the tender K4T30 once I am in Berlin on Wednesday.....

Feel free to request stuff or photos... I will see what I can do. I got a steam locomotive driver with me who will show me around.

An evoluion of the cabin floor panels... the Kit ones via MK1 (a mix of plate and bar frame stuff) version to the final correct one... and the wooden floor planks.


The same with the lateral frame support... Can't show the kit ones, as they are in the trash can in bits and pieces... The Mk1 version as fixed into the frame were bar frame parts added to a plate frame... The new ones are the original plate frame designs for any locomotive produced after the first 300 or so as the first BR52's had a different setup due to a different mounting of the Knorr Compressor (fixed to lateral frame supports (as with the BR50) and not to the boiler)

PS:
Michael, I don't link to my other blog (as to what Carl referred where I helped him out) on other sites, that is what I meant with it. I am fine with linking, but not my own stuff ;-).

Hi Tim,
Hopefully not... there are yet many parts to cut...

Mike, thanks for sharing that. I know why you have not purchased the kit -> smart move 😂. The BR 80 will be awesome and the G10 n stuff from Thunder!

Carl, thank you for your kind words. Not sure if people are interested in the maths and mechanics of spring equalization systems and journal box arrangement discussions😂. I don't link other forum stuff, as I have seperate stuff on both, as I don't copy/paste but rather write kind of different stuff on both, depending on the paths of the discussion.
I do not like it when people copy paste in 10 forums....

Stefan,

I wish to thank you here for the help you gave me, and I'm sure others, on another website. I'm not sure of the rules here, but you may be able to give a link to that site, and let others here in on it. Also, I have photos saved here of the Tank Workshop kit if you can access them.

Have always stayed away from this kit because I knew there would just be too many extra details I would want/need to add but you Sir have taken the "Bull by the Horns" and jumped right in!

Great work - keep it up!

Hi Stef I was beginning to think this had got derailed, good to see you’re back…but it looks like you’ll have to go dark for another 6 months if you’ve got all those nuts & bolts to put on??

That would be a yes.

I would also refer you to a page in the Commander Models online catalog where they have now completed all the patterns and molds for the WWII US built USATC S-160 locomotive that they will be offering. (Not my work) The model only awaits the completion of the instruction booklet to be ready for sale.

The link to the page:

Sweet, thanks Michael.
