Today, I worked a bit more on the ventilation units. These were placed outside, diagonally according to the top view. I made a base from balsawood and then added styrene. I also made the roofs for these units. I had to make them exactly dimensionally equivalent, so that was the main challenge.

I also added the entrance door on the back side of the tower. Detailing will be for later. This week some time, I want to start with the interior. I don't think I will sheet it with styrene but rather prime it and then sand it smooth. All under control so far!

Hope you like it.

Your "history builds" are always very educational to me, @michel-verschuere. I know I will look forward to watching this and come away from the experience knowing things I didn't know before. The perfect kind of project.

Michel, @michel-verschuere

This is definitely taking shape. Each time you post something on this build, it looks even better. Meanwhile I found these pictures I took several years ago of my Dad's Army uniform. This is how he was when he was discharged the last time. He was "busted" back down to the rank of Corporal again... He told me that his rank fluctuated between E-7 which is Sgt First Class and E-4 Corporal which you see here. He never wore all of his medals and ribbons. He said that he didn't want to look like a "PX" soldier. You can see his Berlin Brigade shoulder patch. He was authorized to wear either Armor or Infantry collar brass since he held both MOS. On his uniform you can see the 6th Infantry Unit crest and in this picture you can see Dad wearing his Infantry shoulder braid.

Thank you Michel. @michel-verschuere

I am very proud of my Dad. Thank you for the kind comments about him.
He was part of the 39th Special Forces Group that was part of the Berlin Brigade during his last tour. Somewhere I have a picture of him in the barracks in Berlin. I remember him telling me that they used a building that was once was used as a telephone company or something like that... Telefunken ? It has been a while... Does this make sense to you ?

Michel this is STUNNING and showcases your extraordinary scratchbuilding skills. I hope you would contemplate doing a section of the Berlin Wall as part of this build.

Today I focused on the roof, I printed one more piece on my Prusa i3 3D printer and cut out the roof hatch. Also, I attached the roof gutter. To do that, I used a half round styrene profile and 0.5mm lacquered copper wire. I think it will look ok once it has been painted.

The best pictures I could find on the real roof gutter attachment were these:


I also applied putty to the interior walls, there were some gaps in between the various balsa pieces. I used blank filler because one of the next steps will be to prime the interior white befor the inner side is masked off through the windows.

Hope you like the progress so far.

Happy modeling!

I do like your progress so far Michel. The gutter is spot on as far as I can see, very nice!
