Uuups,
forgot, Ill add the most recent update at least.

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.


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.


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
