The starboard transverse torpedo tube was located between frames 83 and 85, and the port torpedo tube between frames 85 and 87, where the foremast is located. Port always forward of the starboard tubes, as in the battleships of the German navy.
I believe these tubes were mounted at right angles to the longitudinal axis, as opposed to the battleships where they were mounted at a 20deg angle. The depth (centreline) of the tubes was about 1.80 metres below the waterline.
The Revell model of Emden/Dresden got it almost right, I think these were based on drawings Peter G�nter Huff. On these drawings there is a skin doubler shown around the oval torpedo tube lids, however at Revell these doublers were interpreted as recesses instead. The solution is to make a small plate in the shape of the recess, with an oval hole in it, and cement this into the recess, and then file this plate then in line with the skin, leaving only a slight step for showing the doubler. The lids themselves are then correctly recessed.
Hope this info helps!

Hi Maarten, your answer is very complex and demonstrates your deep knowledge of the ship.
I'm copying your answer in my computer to analize it with plans that I'm about to receive. That is very difficulty for me to understand the locations of the frames ( without drawings of the hull lines...) , but now you are clarifying that for me.
Thank you very much for your kind answer, and I hope it can be useful to mate mermaid too.
Nice regards: Jimmy

Maarten, please, I have another question, if you can help again:
this disposition of the torpedo tubes were similar in both ships?
I consider that the only major diference between the sisters were motorization and the four propellers in Dresden.
Thanks: Jimmy

As you asked for the exact position of the torpedo tubes, I tried to formulate my answer as exact as it could be! Therefore the reference to the frames, which is the generally accepted method in shipbuilding to indicate a position in a ship. But yes, it assumes you have an insight where those frames are located! And normally you need a drawing for that, showing the hull frames and their positions...
Well, there is one thing that helps here: by coincidence (!) these little German cruisers of the Kaiserliche Marine happened to have a fixed frame spacing of exactly one metre. This means that frame 85 is exactly 85 metres forward of the stern, the extreme rear part of the hull.
Converting this measure to your preferred scale shouldn't be that difficult, I suppose.
Does this solve your question?
(And a further note for the whizkids here: this way of measuring is different from the RN or other navies, in those the rudder axis is called the Aft Perpendicular and frame positions are measured from this point forward. In German vessels the aft perpendicular ("hintere Lot" in german) is the stern or the rearmost frame in in, and the rudder post is almost invariably postioned at Frame 7 - I haven't encountered any exceptions to that rule yet.
However, the frame spacings differ: while the cruisers have their frames with an interval of 1 metre, the battleships were designed with fixed frame spacings of 1.2 metres, and small vessels (the Gorch Fock) having 60 cm frame spacings. But always uniform throughout the ship, and not variable, as was the case with RN ships. )

In the US Navy frames are numbered from the bow to the stern. Frame 0 is the Fore Peak where the leading edge of the stem cuts the water. Therefore, frames forward of the waterline on an overhanging bow have negative numbers (-1, -2, etc.). The After Peak is the point where the aftmost part of the stern cuts the water. On overhanging sterns the frame numbers continue past the Aft Peak.
The Fore Peak and Aft Peak are the "perpendiculars" and you will see the hull length specified as "between perpendiculars" (at the waterline) and "overall" (from the forwardmost tip of the bow to the aftmost overhang of the stern.
Frame numbering is typically at four foot intervals - I think this applies to all modern ships, but I am not certain. However, ships were sometimes constructed with half frames spaced between full frames. These half frames sometimes were constructed only below the waterline.

Thank you very much for the addition! (although I'm afraid we're veering a bit off topic..., maybe we will get relocated to a more convenient forum.)
I'm leafing through a number of plans I have of USN vessels, and you're quite correct. Maybe because I've got some older plans (USS Midway f.i. in this case), the frames ahead of 'fore peak' (FP or Forward Perpendicular) are called here A, B, C etc. instead of having negative numbers.
While the Midway indeed has 4 ft frame spacing, I found some other vessels having 3 ft spacing, or even varying frame spacing, but always very neatly indicated. My experience with RN ships is you have to solve quite a puzzle whate actual frame spacings were used, designers increasing or decreasing the interval around turrets or in boiler rooms as they felt appropriate.
Having half frames in between seems to be a quite common practice, also with the German Kaiserliche Marine and others.

You are correct about the frames forward of the Fore Peak being lettered. I guess I just had one of those teen age moments.
Also, after thinking about it I recalled thet the US Fletcher class destroyers had a frame spacing of 21 inches. So you really need good plans to be able to locate features by frame numbers.

Does anybody please know the exact locations of these tubes?
Thanks: Jimmy
Yes, an important question for a full hull build. Me too, joining the question.
And you, Mermaid, is that clear for you?

And I thought frames on overhanging stern/bow (outside the perpendiculars, the forward one is the one cutting the CWL, the aft one is the one in the middle of the rudder trunk, cutting the CWL) having negative numbers is a German thing. At least we have a word for it: 'Minusspant(en)' ('minus' frames) ...

Thanks, Maarten and Jimmy ! So on the model that should be represented as a closed circilar opening? It is not quite clear if it should be showing the angle by protruding off the hull or opposite.
How is your model advancing, Jimmy? I am looking forward to see it so there will be less questions left. What guise are you going to portray it? With the false stack or without?
The torpedo tube aperture should look something like this:
. This example is from SMS Ostfriesland, and will be slightly larger than on the cruisers: 50 cm torpedo's instead of 45 cm.
Not circular, but oval with square topcorners, and slightly recessed. Note also the reinforcing skin doubler, which was mistaken by Revell as being part of the recess.

I'm convinced the torpedo apertures on the cruisers were entirely similar to those on Ostfriesland, only a touch smaller. The only difference I can see is that on Emden (and Dresden) the top corners of the doubler plate were cut off, instead of the bottom corners as in case of the Ostfriesland. This because the underlying skin plate situation was slightly different.
The Germans were pretty steadfast in repeating a good design over and over again in their ships...

See what I mean? Almost exactly as on the Ostfriesland.

Coming in late to the subject, recently picked up the Revell Emden and am eager to amass all the research and aftermarket details nessisary to get the job done. Is there any aftermarket details currently available? I noted Gold Medal being mentioned some posts, and years back, are such still available?
I must be missing something? If you mean the first page of this thread, yes, I saw mentions of various things, but as those posts were five years old, I wondered about new/better/different?
He might be referring to the front page of Modelwarships.com, where all the banners are, including the one for GMM and various online vendors. In any case, I do believe that the GMM set is still in production and can be attained relatively painlessly
