GPM's Seehund and Biber 1/25

Having built the Hecht and Molch, last year, I just had to make the newer GPM’s midget submarines – Seehund and Biber. For the moment, I only decided to make the Seehund. So, maybe this thread will be a two-part one, with some time in between :rolleyes:
I start with pictures of the kit. In low resolution, for obvious reasons.
There are 6 pages of parts, 4 more with construction diagrams and the covers. Beautifully printed :) in very thick paper :(, as usual with GPM.

The torpedoes are equal to those on the Molch. A good point is that there are some variations in colour effects.
For the tips, I used the rolled paper method, as shown in the pictures.

Hi Ricardo,

1/25 scale means a lot of detail parts you can add?
Did you put skin on rolled paper when glue them together?
Using rolled paper seems it is not necessary to file it. Isn't it?

Hi Yu, nice to see you here :)
You know that I am too lazy to add detail, whatever the scale :rotwerd: (apart from a couple of rivets on train models ;))
My 'business' is just to assemble the kits using the least reasonable extra materials and tools. Please don't ask what I mean with 'reasonable'. I'd really be in trouble to give a reasonable answer :D
I find it convenient to use rolled paper to serve as a basis to glue the slices of the kit's parts. Each torpedo nose has a part (well, two parts…) with 14 slices. Instead of gluing each slice to the next, I glue them all onto the rolled paper base. Much easier, if you ask me. Less risky, too, because the glue is inside. You can say that the kit's part works as the skin of the rolled paper base. The trick, of course, is to make that base with the suitable shape :rolleyes:

Hi Recardo,

Thank you for your detailed explanation as always.
Even if you try to fool me disguising your character saying you are lazy, I will not be tricked. I have already observed your meticulous works. Lazy guy must not be able to do that :D

Instead of asking you about ‘reasonablel’ I took out my secret weapon- OXFORD Advanced Learner’s Dictionary- and looked up 'reasonable'. According to the dictionary ‘reasonable’ means ‘as much as is appropriate or due’, hummm…… x%#$ ?(

I'm tired. I must go to bed before bed comes to me... good night.

Fantastic secret weapon, Yu :super: The definition is just broad enough to fit anybody's needs. Perfect :prost:
As the middle of the torpedoes is just a long and slim cylinder, I went straight to the tail. A bit of rolled paper is also useful, here...

Hi Ricardo,

I always feel admiration for your fundamental techniques such as cutting, bending and rounding paper.
Lately I remind myself to back to basics.

Ric,

your build looks very nice and clean so far - but who would expect something else from you.

To add to the realism of the model, you might want to add a second set of propellers to the torpedoes. German torpedoes at that time had two counter-rotating screws.

http://images.google.de/imgres?imgurl=ht…4__204%26sa%3DN

I think this error is in all of the GPM midget submarine models.

Thanks for the post, Michael :) You're right - the torpedoes on all 4 GPM's midget submarines are equal, apart from colour effects.
They do have counter-rotating screws but with just 2 blades each. If I got it well from the drawing you pointed to, it seems that they should have 3 or 4 blades each!
Another difference is in the submarine's screw. On the GPM model, it is well inside the shroud. On the drawing, it is well before! I wonder which one is correct...

One or two propellers?

Hi, Ric and Michael!

I think, the german midget submarines in WW II used this kind of torpedos:
Modell G7a T XIV

This means:
G stands for calibre 533,4 mm
7 stands for ~ 7 m long
a stands for air-pressured propulsion
Typ XIV with reduced perfomance was special developed for midget submarines.
This torpedo had only one propeller with 6 blades.
At the air-pressured propulsion a fuel (Dekalin = Decahydronaphtalin) was combusted with pressured air, the produced hot gases were leaded through a nozzle to the propulsion-propeller.

Ric, don't panic - I think, the GPM-torpedos for midget submarines with one propeller are correct, but they need 6 blades!

Ully

---------------------------------------------------------------------------
Uff, da hab' ich 'ne halbe Stunde mit 'nem dicken Wörterbuch für gebraucht! Das ganze noch mal in Deutsch:

Ich bin der Meinung dass die deutschen Klein-U-Boote im WK II folgenden Torpedo einsetzten:
Modell G7a T XIV

G heißt Kaliber 533,4 mm
7 bedeutet ca. 7 m lang
a bedeutet Druckluftantrieb
Typ XIV war ein G7a mit verringerter Leistung für den Einsatz von Klein-U-Booten.
Dieser Torpedo wurde angetrieben von einer Sechsblattschraube.
Beim Druckluftantrieb wird ein Treibstoff, zumeist Dekalin (Decahydronaphtalin), mit Druckluft in einer Brennkammer verbrannt; die entstehenden heißen Gase werden durch eine Düse auf den Antriebspropeller geleitet, der den Vortrieb bringt.

Die Bilder zeigen "Marder" und "Seehund"

Hmm, dann sind alle meine Abbildungen & Informationen aus dem 2. WK falsch!?

Das Klein-U-Boot "Marder" könnte auch ein Ein-Mann-Torpedo "Neger" sein, bei letzterem soll der Trägertorpedo deutlich länger als der Gefechtstorpedo sein (?).
Der Name "Neger" geht übrigens auf den geistigen Vater dieser Waffe, Marinebaurat Richard Mohr, zurück.

The name comes from the inventor, Richard Mohr (in German 'Mohr' is an oldfashioned 'polite' term for negro).

nun sogar auf deinem rechten seehundfoto hat der aal 2 schrauben,man kanns nur schlecht erkennen....
auf allen fotos die ich habe sinds immer 2 schrauben wenn mans erkennen kann.
vielleicht gibts ja jemandem im forum der sich die torpedos betreffend so gut auskennt dass er sagen kann wies wirklich war....

Oh dear, this is a complex matter! There is a lot of variations, right?
The good news is that the torpedo on Ully's first picture has a screw arrangement that is well matched on GPM's minisubs - counter-rotating with 2 blades on each screw. And the blade shape looks good, too!
Well, hopefully, the submarine stand is less problematic...

Hi Ricardo,

From time to time I dropped notes praising your build. But to tell the truth in my heart I expected you to mess up out of jealousy so I have been keeping sharp watch for even small mess up. Now I realize I have to dismiss such petty idea because it will never happen.

Greeeeeaaaaat build!!!!!!!!!!!

Hi Ric,
congratulations on your built. Really nice!

I think at the last International Meeting in Bremerhaven we had the table in front of a submarine of this type.

Does anyone know if it is really a Seehund in the museum?

Cheers

I starting to be afraid of doing mine, because it will be light years from the quality of your model!

Jan@ For those two pictures I would say that yes, that submarine is a Seehund.

Many thanks for your kind comments :)
@ Yu - I like your sub, too :prost: Very colourful lettering :D
@ Jan - If the sub on the pictures is not a Seehund, I am an alien ;). I was shocked by the small size of the real thing: not much more than an ordinary car 8o. And the Biber is a lot smaller!...
@ zec - Not possible yet :( I'm just starting with the Biber. But that will come...

The Biber is a lot smaller than the Seehund. The kit has just 4 pages. One for the torpedoes, another for the stand and just two for the submarine itself. The number of parts is slightly below 300.

@ Hartmut - nice to hear from you :). I'd say cigars, instead of cigarettes. You know, the scale is 1/25 :D
@ Yu - correct :). For the hatch and also for the tiny domes in front and behind. 2mm diameter and a lot of slices...
@ lriera - thanks :) I'm following your Jeep with a lot of interest, too ;)

Today, I show the torpedo holders and the submarine propeller. This one is actually smaller than those on the torpedoes! GPM's thick paper is plainly (or painfully :( ) visible here...

The submarine hull was difficult to build :( The cross sections are somewhat complicated and GPM's very thick paper definitely doesn't help. Fortunately, part of the misery will be hidden by the torpedoes...
