BR 52 - Kriegsdampflokomotive 1 - 1:35 Kit

Recommended Posts

 

The first 120+ frame holes drilled. Mostly bolt head outside + nut 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. 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, most are 1.2mm. I wish there was a miniature bolting machine, I want one!

However... I have the amount of holes marked on this list and on the respective parts... so another 220 missing.

Then I will need to drill and rivet up all the frame interiors... And then:

These guys up top... The ones below on the right are parts of the ash pan and were mostly welded and the left bottom parts are exterior frame parts included above already. In total about 3200 (if I would add all interior ones and for the housing and so forth, which I won't), I'll have 1500-1800 in the end I think.

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!

 

To get the bolts 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.

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.

45934669021_8d7ef09087_c.jpg

 

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

44008665260_134de87d0a_c.jpg

 

Or the 52 8173-9 from below:

30885273837_c1b0089656_c.jpg

 

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.

*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.:

Time to cut all these guys...

45877745432_3dd68d9063_c.jpg

 

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.

Well, hits took much longer than anticipated, but I have 650 holes drilled as of now and shortened about 1400 rivets n bolts.I can't add them in full length as I did here, as I need to add the bolts from the other side and as such, all need to be cut to approx .5mm length, to fit into the frame, but not all the way through it.

These are the first 6 1,2mm hex bolts holding some interior frame support structure. All is still in dry fitting and as there are so many connections 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. Maybe I will glue it all in place on one side and then add all bolts n rivets before going on?

Additionally I need to keep track of the bolt kinds... 😀 This is way too ridiculous now.

44008665260_134de87d0a_c.jpg

 

 

It feels like an endless cleaning job and re-drilling from both sides until all is clean and ok.

45984005981_3d166b4a37_c.jpg

 

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).

44167905010_614e7f3a1a_c.jpg

 

After adding random bolts to check for the corret alignment... It seems to be quite nice.

Well that''s it. Maybe someone has a smart solution as to how to tackle this one.

Thanks in advance,

Hi Stefan.First off a great build you have going here.I have not yet tried what I am about to say BUT I am confident that it should work.Instead of having to drill from both sides for the cleanup part have you ever tried sticking masking tape to the backside of the plastic before drilling it should then in theory stop a bur from forming and save you some cleanup.I do this often when making knife handle scales from bone and wood.

 

Regards:

Shaun

You started with a kit and then, something went horribly, horribly......horribly. Wrong.

 

Nice progress.

Shaun,

never thought of it, thank you very much. I will try method this the next time.

Haha, actually I wish I had gone the kit's way. Will see how this continues. Now tome for the scorpions :) and bed.

Good night,

Actually, quite a bit pf progress has been achieved. 

It's still a war with the rivets, but at least the first battles have been fought. 

Last fitting and alignment tests before the first few hundred were added.

So far mostly 1.0 and 1.2mm sperical rivets have been added. I added some 1.2mm hex bolts and started preparing the nuts. Also waiting for the next delivery of some more 1.2mm ones, as I ordered too few of them and too many small ones.🤔

The frame top support also received quite a few rivets and hex bolts.

100% in accordance with everything said above, I regret not having seen it, I think I have become confused with another WIP that has made another locomotive.
The work is totally amazing....:popcorn:

Cheers mate :santa:

Amazing work, cannot wait until this is finished. Insane amount of detail done so far!

 

Keep it up,

Mark

Mark, this will take some time. In the meanwhile check out Steve’s BR52, he finished his recently. It is an incredible built and he added lights and tons of extra, it is an amazing piece of art!!!

 

Hi Francis,

Nothing much happened here besides drilling and research 😂. Steve’s progress was much more entertaining, I am glad you enjoyed his work!

 

I got some PE parts from voyager sent to be reviewed by a fellow modeler, actually by HH Bühling, the guy with all the BR52 photos on prime portal! Will compare them with the Big ED set and stuff soon.

 

Have a good weekend, thanks for checking in. My ears are deaf now, Pretty Maids and Helloween were too loud at the gig yesterday😂😂😂

You seem to be a real nuts and bolts fan 🤣

 

P.S. You Avatar picture is ... disturbing. I hope it isnt someone you actually know. 😨

I don’t like bolts at all, they are annoying.

 

Soeren, this was a ”Bollenhut” and Black Forest traditions promotion thingy. It involved wigs and Bollenhüte😂
