Great job Chris! The colour looks fine to me but I would give it a brown/black wash to darken it a bit but that's just me. Could you tell me what are those "black boxes" on deck E?
Happy New Year!

The 'Black boxes' are waterproof electrical cable junction boxes for the GHG.

There is a fine paper about GHG equipment at http://www.cdvandt.org/GHG1996.pdf
It references pre-amplifiers, which I think may live inside the waterproof junction boxes. It also explains, if you follow through the entire paper, why the GHG was placed where it was on a U-boat - Interesting stuff!

Thanks to Maciek and Simon both for clarification! I am always looking for more documents like those that are primary sources! My German is improving also! So, would those junction boxes, given that the wartime materials restrictions were in place, would they have been steel, aluminum, or even possibly Bakelite?

On my model I painted them black arbitrarily but if we know what material the were I will change the coloring accordingly.

As always, gentlemen, I thank you for your input.
Cheers
Christopher

I would tend to agree with you. Perhaps I shall render the boxes slightly more metallic.
I think I will also rubberize my soft electrical cables, but will keep the hard conduit bronze or galvanized.
Since we know that every air line and interior electrical lines had color codes, is there any known color coding on exterior wiring and exterior plumbing? Not that small marks would be easy to see at 1/35th scale, but it would be good to know.

We believe no colour coding on the exterior piping.

I would say hard conduit, bronze between 1939 to 1943 after 1943 galvanized for sure!

I not sure about the electrical lines being color codes :-\ Have you got some information on this ???

Each mark is at least 150 mm long (so that 4.3 mm for your boat), and where a second color banding is provided, banding consists of one section of basic color 60 mm long at each end, with intermediate bands as necessary, each of which is 30 mm  long.

Hmm. I thought I read in the U570 report, or some similar document about electrical lines being color coded also, but I might be mistaken.

Perhaps it was that the electrical fuse boxes and junctions were labeled extensively. I will see if I can fund where I saw (or think I saw) ref.

Till then, Pr

So Here is a little more work.
This is either a close-up of Shatner's third season hair plugs, or it is the GHG I am installing. :-)

As you can tell I used an Arizona Tea Can for the skin. This seems to work well, and "Oil Canning"
should be interesting.
I drilled out the holes for the GHG sensors and then, after careful filing with a round needle file,
inserted them into the holes. A drop of thin CA secured them. From the outboard side, I lightly sanded
the face of the sensors to make them flush with the skin.
Also added bolts to the tubes to hold in the tube liner.


.
As you can see I am starting to add some texture to the tubes and end cap for the Druckkorper.
I will also need a comb and some good conditioner to straighten out the hair!

.
Here is the GHG dry- fit, looking outward from the inside of the boat to the Stbd side.

.
The cut off point for this plate is the stringer. Two of the GHG sit above this stringer, so will be added afterwards.

.
This is showing the chain locker, the Arizona Skin

.
The major sections are still in a dry fit status, but I am to the point where I am going to start attaching things permanently to the keel.
I will have to lay in the lubrication lines for the tubes, and finish placing the bolt heads and flanges, and some other details.
Then I will fix the tubes and chain locker to Frame 106.
Then Deck E...
then Stringer #3..., then the GHG leads to Deck E...
then...
...then...
Cheers
Christopher

Quick question Gents -
The 90 degree vent for Tauchzelle 5, on Deck "E"  -
Is it a single piece cast iron construction, galvanized smooth steel, or is it made of wedge shaped (tubular) sections, like modern tin ductwork?
I am working on that section for my boat, and can find no refs for the material and construction.
Also, about the red oval encircled area - does anyone know if that "I" girder that the mechanism to open the vent goes from Bbd to Stbd Frames, or is it a separate mount?
Will post pics in the near future of the progress, but it would be helpful if anyone has this info.



Thanks!
Cheers!
