Any ideas gents?
... where did you get the drawings that your working with?I am taking refs from all over the place - the K
As you can see, I used a copper colored coated cable (.025") for the connections for the GHG, but have a question...
Were they sheathed cables in real life or were they a rubber coated electrical cable? I can find no refs that say what the material was.
Now I need to work on the windlass and vent fixtures for Deck "E".
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 (http://www.cdvandt.org/GHG1996.pdf)

It references pre-amplifiers, which I think may live inside the waterproof junction boxes.
I not sure about the electrical lines being color codes
Question to the masses: Were the air bottles on the boats painted a different color, as high pressure bottles tend to have
done to them in modern times? On U-995, many are currently blue, but I believe that is a modern thing.
It is naturally starting to get cramped in there - but I have a lot more cramming to do.
In real life it was real restricting in the bow, at the smaller scale it must be a nightmareIt is challenging, that is for sure. As I am sure you know from your work, fitting objects into places we think they fit into is not always as easy proposition!
hello,Bruno
I find your work really great research in the details!! are also working on a Type VII U-boat and seeking documentation and especially the plans, could you tell me where you purchase your thee documentation for precise dimensions.
thank you by before
good luck
Bruno
Good day Gents!
Here is some more work, and a number of questions.
I have done some work on the druckk
Secondary question - the row of small round drainage holes in that area of the bows and the structural work that supports the steel part of the casing on both the Atlantic and regular bow...
I assume those holes sit above the Bow buoyancy tank, or are somehow sep. from it, but that whole construction is puzzling.
... it is making me scratch my head a little!
It is funny, because till you try to draw that area of the ship, and then try to build it in miniature, one is easily tricked into thinking that part will be easy.
I have come to believe this part of the boat is one of the must complex parts of the boat.I agree with you ENTIRELY on that!
Hi both of you
I`m not going to interfere in you very detailed discussion on a subject where you have more expertise than me, but I`m posting my detailed photo of KNM Kaura`s (ex U 995) atlantic bow at the time she was untouched by the museumspeople in Germany. I`m not sure if it can be of any help though.

Christopher
This particular fjord up in northern Norway is called the Trollfjord and is more known for the narrow entrance rather than depth . But in general the depth of the fjords are max 1000 m. The depth of the fjords together with icywaterivers from the glaciers made it an excellent hide for the submarines. The difference in temperature and salinity made waterlayers which created a "reflectionmirror" for the sonar and you could registered the different layers by sensors. When you found a proper layer you placed the sub rigth underneath and shut off all motors so everything was dead silent. The trim could be kept by lowering and raising the periscopes into the other density layer using the accumulated hydraulic pressure,( no sound).
This was the ultimate excersise for CO`s of a submarine and many of us were convinced that the numerous observations of foreign submarines in our fjords were ideed foreign subs training CO`s for this such operations.

I must say it was the first time I was more delighted to see a landscape than a Type VIIC ;D The fjord look very similar to NZ Fiordland.
Also very cool about how to keep the trim with the periscopes!
... and there was a point where I was "wet" more than I was dry in my life ...
I guess is that is probably why you call it Fjordland, we call Norway the land of fjords. The major difference though is that most of it is above the polar circle and during the cold war year a little too close to the related activities.

In fact if I think about it, I have been caught in more avalanches than days spend at sea :-) :-)Simon - I hear ya!!!
ToreRigth you are Christpoher. Deligthed to hear you are, I presume, a PADI divemaster. I myself got my first diving certificate in the pioneer times 1953 ( thru the navy) and the in the certificate I was registered as "shallow water diver" you would laugh today if you saw the equipment. Since then I renewed the certficates both as PADI advanced open water diver as well as CMAS. Apart from diving all along the Norwegian coast, I did (together with my wife) a lot of diving in the Maldives, Red sea, and Caribbean. My biggest hobby (and most expensive) was underwater movies and we were hopping around the world with 32 kgs of equipment the excessive luggagecost was substantial. But you are rigth, you could as a scubadiver literally see "rivers" of water with different temperatur and salinity. Not so onboard the subs, it was sensors attached to long cables able to take readings at quite a distance. When the sub was in neutral boyancy you could ballance her at your fingertip (a small exaggeration),but as an example, we were 46 men onboard an prior to the claxon sounding for divingstations the officer on watch ordered: pump 400 liters from forward trimtank to aft to compensate for the movement of the men. I was usually already on my way to the controlroom at that order. So the the good old VIIC was ticklish but with some speed you could hold her within limits by the hydroplanes
I became a scuba Dive Master probably 20 years ago, and there was a point where I was "wet" more than I was dry in my life.
I have dived in tropical waters and cold waters, deep and shallow, and in all kinds of weather.
One of the things that I think a lot of people do not realize is what those salinity layers are, and how effective they can be.
One of the more interesting places to dive for me was where the South China Sea meets the Pacific. Two different types of water, and it was such that you could, just like a submarine, achieve neutral buoyancy and stick your hand in and out of salinity layers that may have been many degrees different. You could FEEL your hand cold, while your body was in quite warm water.
We did not have onboard Salinity Meters but you could sometimes see with your eyes water that seemed "thicker" - sometimes with more brine or plankton. Your hand could feel different temps of water.
It makes me smile to think that you trimmed the boat in silent running mode with the periscope and accumulated hydraulic pressure. Not only would the trim be affected by the mere physical extension and displacement of center, but one would think that moving a column of air that is inside the tube higher or deeper would affect buoyancy by its expansion and compression. Even a few meters of change can affect the volume of gas.
Cheers Sir!

I think a big different between the Norway and New Zealand fjords is the rainfall, we have extreme rainfall (between 8 m to 15 m a year). I live only about 60 km away from a place that get between 18 to 20 m of rain a year but where I live we only get about 2 m a year :D

Good heavens, I hope you get it mostly as rain and not snow otherwise you could end up with some 150 meters of snow. We think 5-6 meters of snow up in the montains is enough.

Yes,apart from the very advanced "hanging" underneath a different salinity/temperaturlayer an absolute dead silent condition could be nessecary in other places.We had silent running procedure which means you could hold her by hydroplanes at a very low speed, the VIIC`s had bad steelpropellors susceptible to pittings and could easely produce noise, so the safest way would be to put her on the seabed. All auxiliaries were mounted on rubber chocks and tools were rubbercoated. The crew moved silent around only when absolutely necessary, Das Boot gives an excellent example of this condition. We had noisetrials every so so often and each auxiliary got its "noise certificate" but we shut off all nonessentials including ventilationfans. Yes noise is a subs worst enemy.Quote...Deligthed to hear you are, I presume, a PADI divemaste...
Tore, I am indeed a PADI divemaster. We could no doubt start a whole new thread based on diving (we are, after all, miniature submarines in that aspect, and have a lot of similarities with our bigger steel brothers!)Quote...So the the good old VIIC was ticklish but with some speed you could hold her within limits by the hydroplanes...
would there be times when you would have to hold her dead still, submerged? I would suspect that even single crew moving from compartment to compartment could upset the trim a bit.
It look like that you may have miss a man hole cover on this bulkhead.It looks like the manhole you are referring to is about the same configuration as the one on "E" deck as far as size and bolt configuration. Where did you get that reference Simon? How high was it above the base of "E" deck? Do you have a drawing that you used to generate your image?

I see you are busy with the forward atlantic bow details. Many people have been discussing how the surface of the forward steeldeckpart looked like as several kits shows all kinds of surfacepatterns.Thanks for the detail pic Tore! Very useful. I assume those surface bumps were something like raised weld beads and not rivits. I will have to place them on my deck. That is the best pic I have seen of the actual surface of an atlantic deck.
I`m posting a photo below showing the details of the original VIIC/41 as on Kaura.

I think they were more like pressed out knobs (intergrated) in the plate rather than weldbeads, definitely not rivets.

I will test to see if it would be more useful on my model to actually dimple some thin sheet metal from behind to get the effect, or to use putty or some such to apply the detail to the existing plastic casing I have!
ChristpopherQuoteTopher, cabling is excellent, one of those details that 'sells" it.Rokket - Thanks -
It is slowly starting to build up to the cramped environment that we are trying to replicate.
I am constantly working on my pre-model drawings so that I can fit in details as the build progresses, so I don't get stuck later.
For instance, I have the forward dive planes and their mounts in, and I have the drive motors, but it seems that the push bar between the two will be viewable from my planned cut-aways, so now I have to figure out how to squeeze one in place.
Fortunately, I do not have the skin for the chin floodholes in place yet, as that would make putting the push rod actuator impossible!
Among many challenges are making the decisions of what to include so enough is represented, getting them to look enough like the actual parts, and making it all look believable.
I am constantly raising my own bar as far as modeling skill goes with this project, but it is interesting in that each bit i get work done on makes me re-evaluate if it could be done better. Some things I leave that for "the next one" and some things bug me enough that I rip it out and do it differently right here and now.
I intend to finish the framing and casing sections in the near future, so then I can begin to work on the area of the actual torpedo room. That will have many challenges as well - like the curved torpedo compensation tanks and the below-deck torp stowage racks.
I am working on the drawings for them already.
I guess I do not pick "easy" projects! :-)
Cheers

Yes that right, 10 mm for the knobs & 20 mm for the steel plate rivets, was what I workout. I believe this style of plating was used only on the decking. The German’s used a different style of plating inside the boat.Yes you are rigth.

Purists may hate me, but one idea for the tiny bits in the guts is to be "representational" - ie the pushbar can be seen as a shape and a bar, obscured by much, so it only has to be "something" there. I found putting in my p-hull that so little was visible, the basic shape and a few details were all that was needed.Rokkets.
Fantastic work, this is quite a project.
anti-slip bumps - I'm certainly not only least qualified here, but additionally far from an expert, but I can easily see from the pic that they could be stamped as Tore says, or equally plausible big rivets. I'm leaning to rivets, as some of the heads look mighty "big" and "separate" to be stamped, altho hard to see with paint.
Internal floorplating.
Down below is a small picture of what I as far as I remember shows the pattern of the VIIC internal floorplating.

Your two very good pictures of the bullnose is a bit bewildering to me as on KNM Kaura the bar framing the hole is not forming an oval(circle) but rather an U shape where the two "legs" are ending on both side of the bow as shown on the two photos below. ( May be we are going into to many details here?)

Exellent pictures. If these pictures are of the originals U 995 then it is clear that the floorplates are aluminum and my memory fails. I remember the floor darker like the picture below. It seems to me that these pictures could be from the Laboe U 995 and they have done a lot of changes to her since the wartime. The colours of the engines was definitely grey and not green as on the picture.The pressuredoor to the controlroom did not have the fancy yellow stripes and dots. The tables were natural oakwood coloured framing, the tableplate was linoleum definitely not painted green as on the picture.See my picture of the area from the same position in 1953 and ignore the young lieutenant.Internal floorplating.

I'm pretty certain that U995 as she is now is wrongwrongrong...the yellow stripes are for safety (tours), and the aluminium plating is new. The pattern is modern and the old ones were steel and show rust. At least on U505 and in USN Gatos... aluminium was for aircraft back then! My 2 cents anyway...I think you are rigth. I believe today U 995 is more a tourist thing rather than a correct restored U-995/41 . To my opinion it`s a pitty they have made all the incorrect changes, both to the casing as well as the interior colours. As have been mentioned before, modellers should be very careful in using her as a reference they way she look today.
Here is the progress I made last night, and today...Christopher
Below you can see I added an indication of the forward dive plane pushbar and mechanism gland,,, I also added a few more of the forward frames to complete the sealing end of the tauchzell. Now I can add in the remaining forward frames.
(https://www.kabutographics.com/_VIICBuild/__Pushrod001100_5659.jpg)
Below you can see that I have started on the undercasing parts for the atlantiksteven, and will soon lay in the plates forming the bow buoyancy tank, and will have to build in the tow hook and tow hook well after I do the tank plate..
Behind it I have built in my deck stowage locker on the Bb side.
I have added a mechanism for the vent, as well as a top grating for the same through the bow casing. I painted my vent mechanism bronze, since it seems to me it should not be a part that is prone to rust, but if there is anyone who knows what the vent was constructed from, I can change that.
You can also see the grand layout for the torpedo lubrication lines for tubes I - IV. I am slightly worried that I made these lines a little too heavy, but it does not look bad to me. Again, base coated them as bronze, but will probably tint them to be copper.
(https://www.kabutographics.com/_VIICBuild/__Misc100_5658.jpg)
Below you can see the lube lines a little better, including the access boxes and nibs, and the anchor chain.
Now I can secure the ends of the GHG cables to their through-deck plugs. Just visible is the vent for the bow buoyancy tank on the topside of the deck.
I also made the bolts visible in the "E"Deck access hatch stainless steel, so the crew will not have to worry about rusted out bolts! :-)
Simon - Were you able to find a reference I could look at for the missing manhole you mentioned I should put in? I can find no reference in any of my material.
(https://www.kabutographics.com/_VIICBuild/__LubeLines_001100_5661.jpg)
I will have to put in the mechanism for the main vent for the tauchzelle and the actuating universal joints, but that is still a ways down the line yet.
Well, I am off to build a few more frames till the Wife comes home.
Cheers!
Christopher
The man hole at Spt. 102 has a diameter of 650 mm.Thanks for the info Simon! :-)

I am slightly worried that I made these lines a little too heavy, but it does not look bad to me.I quote myself, and the more I thought about it, the more I did not like the former lube lines I laid in. In scale, they would have been over an Inch in diam. and that is wrong. So, i ripped them out and did them again, in a much closer to scale copper wire. As we sometimes say in the states... Mo better! :-)

For that reason there are 8 automatically switched on battery powered emergency lamps, 9 mountings for battery powered hand lamps and 8 battery powered hand lamps located as follows: Forward torpedo room 1 Battery Powered Emergency Lamp on bulkhead t D.Spt 63 and 1 Battery Powered Hand Lamp - Mounting between frames 69-70 on the port side.I can find the device between 69-70 with no problem, but am curious as to where on bulkhead 63 the device is...
also...Each boat is equipped with 8 battery powered hand lamps, whose location is shown in the preceding table. To help with location, the power switch of each lamp is surrounded by a ring covered with luminous paint.
I can find the device between 69-70 with no problem, but am curious as to where on bulkhead 63 the device is...Emergency lamp is on the port side of the hatch, labeled with "Notbeluchtung", but without the bulb (only the hole for it).
on the kabelbild der licht I see 3 circuits on the Bbd side and 2 on the Stbd side of the bow compartment, but it does not show the actual location, nor does it show the colors of the lamps in place.Well, I'll post my thoughts about lamps locations soon.
Will keep looking, but it seems to me that this compartment was not an overly well lit place...
Could you point me the mounting between frames 69-70?Maciek,
I did see the notes on the "nightlight" at the end of the report, but do not know where this would be wired into the room either.
On the Kabelbild the rectangles are not the lamps, but distributing boxes. The lamps are connected to these boxes.
I have counted 9 lamps in the forward torpedo room: 5 port and 4 stb. In the tubes area there are 3 lamps (one
you have located at the image from u-historia), there are 2 more lamps just forward the tubes.
And you could always show just one tube open...I am likely to do just that, but will have to go in and do some serious (and careful) hollowing with the dremel tool.

Progress:
So I just designed some 1943 KM bed sheets in Adobe Illustrator, blue stripes on white, and some medium gray KM wool blankets with blue edge stripes, and a white KM Eagle, in 1:35 scale. I printed them on 100% cotton rag paper, and took sanding paper to the back of it to thin it out. I broke the fibers about two hundred times over the sharp edge of my calipers in every direction possible, front, and back. I now have very soft, foldable sheets and blankets to place on my bunks.
I crunched them up a few dozen times, unfolded them, broke the fibers again over the calipers... and started gluing them to my bunks.
I will post pics tomorrow - but I am happy so far with the results. I have coated them with Testors dullcoat to even out the color. That is drying now. I am going to do a similar technique on the bottom of the bunks to simulate the springs - (no softening or major folding - just printing) just in case someone peaks that far under in the finished model.
Going to bed with a happy modeling feeling... :-)

Thanks Gents! I will remake the beds! I used a reference pic from Bavaria Studios that showed blue and white stripes. It will be no problem to come up with a new pattern. The image in Tore's pic have a larger pattern than the other pics. That will make for a more visually compelling image I think. I will make the blankets a little darker, as these dried a little close in color to the sheets, and I want a tad more contrast. I used a historical replicas website ref for the blankets, but do not know if it is "period". Any objections?The blankets with the german eagle and swastika was never used by us of course, but we had dark gray blankets (I guess german) which were put in a blue and white checked cover (bag). There were indeed two different sizes on the checkpattern of which the larger checks were in majority. The beds in the center were more like a canvas stretcher and not like hammock as on UK subs.They were mostly stowed away during daytime (poor junior sailors.)
Christopher
Ps: the larger torpedoroom pics are just about how crowded I want to have my boat looking. :-) I"ll need to junk it up after I get the regular details in!
Is this a Type IX? The lockers are different from the type VIICs I have seen?This is type VII - in the background, between the torpedo tubes, there are visible control shaft for the anchor/capstan motor and motor driving shaft. Such arrangement - with the motor in the bilge, between the tubes - was on the type VII boat's. Type IX had motor under the ceiling - just like U-995 today.
How does this look? Better? There are trim lines so the colors will go to the edge of the blankets and sheets.Christopher I believe a fraction more white would do it.
I figure I should get thumbs-ups before I remake the beds.

Oh my.... Now this is real deal build! I love the details. Looks like i really have to buy that set of plans as soon as possible :)Marko you`ll get the best VIIC model interior ever I bet. Looking forward to seeing the progress.
Wider is better...Yes Christopher that`s it!

I agree it is a possibly the mountings are for the depthgauges, that was my first thougth and I have been looking for evidence. Maciek know more than me about the torpedoneed for knowing the depth,but I am pretty sure there was a depthgauge both forward and aft.
In control room were two repeaters - one near the rudder station (at forward bulkhead), and one near the navigator table (wall type) (both are missing in U-995). I think that the wall type was fixed mounted, and the helmsman's was moveable:I found the picture of the second, wall type repeater - and now I really do not know, which one could be moved to the aft toredo room, because both look detachable...

It doesn't match to the mounting you marked in the aft torpedo room.
If you compare the Sbd side of the metal wall in the aft of the fwd torpedo room -the one with the valves- the Bb side metal looks cut away. It is decidedly something that was removed. Drawings show that as being a storage locker. I could see the emergency tools and maintenance equipment in there, but the Bb side is definitely altered.Could you marked the parts you are talking about on the pictures?
Is the way that the angled deck plating is finished here the way it was on VIIC's and VIIC/41s, or is this a later addition for the KNM Kaura or U-995 post-war?
I notice that the Sbd side seems to have a cut out section, but the Bb side does not. What is that cut for?
Also, what is the device to the left of the green valve and flow-meter? It has a black painted shaft or pipe leading at an angle into the deck, and looks like it might be geared (it has lube points), but it looks like a pipe leads into it. It is not on the Bb side.This is angle-gear for the shaft, which drove the forward diving planes, when the electric drive/control was damaged. The shaft was led on the stb side to the control room, to the diving planes control station - on your photo is cut because of the entrance. The other end was led below the deck plates, between the tubes, to the coupling (which was control by means of low compressed air) and then drove the diving planes.
I believe, it is not original, but maybe Tore will confirm this.Maciek,
Do you have any pictures of this area on a Type VII? I have never seen one, and only got my picture from http://www.deutschland-panorama.de/museen/laboe_technisches_museum/ps/10_1051_06.php (http://www.deutschland-panorama.de/museen/laboe_technisches_museum/ps/10_1051_06.php)Well, maybe these photos help - they are from Lothar-G
if this is your first shipbuild god man cant wait to see your next !fine work my friend love the scale of 1/35 also i think it is a great scale to really go all out . 1/25 is also what i call builders scale !great work ladd cant wait to see more from you ! all the best !

If it were the stern tubes of a type IX, the tubes would not have been labeled I & II.
The Officer looks familiar! :-)I hope, you don't mind I have used your crew member :)
I have never seen drawings of an X B so thank you.
Tore - Do you remember if the lower bunks had a bunk fence on them? Drawings show they did, but that may be a drawing convention.I don`t think we used them because the lower bunks were used as a seating and normally the tables were mounted.
Christopher
ChristopherWell, Guys - here is some more work. I hope I have the spacing right.
I got a detail picture (bad) of this area where you hopefully can see how it normally looked like. The tables were easy to remove but as rule fitted as shown.

Also, when I go to build my cut-away version of the Famous U-35, I would assume she would have as a typical load-out of G7A's?. My U-35 will have the torps more visible as i envision it. Does anyone know or have drawings of the external differences between G7As and G7Es?
When i was in the US Marine Corps i learned about various coding and color codes for ammunition. I am still surprised that there is not a reference for WWII Deutsch Torpedo codes.As far as I know, some color codes were used for pistols and (likely) warheads. Simple color codes were also for torpedoes, to distinguish versions with different steering gear (simple gyro - straight runners, or various variants of pattern runners - FAT and LUT).
As far as I remember, I did not read about it on the web, so I will have to look for in my paper sources.
Can you list the codes you mention or can you point me to the places on the web I might see them?

A green band along the tail-piece of a torpedo indicates that it is fitted with an engine of increased horse-power.http://uboatarchive.net/U-517INT.htm
A green ring around the depth-setting indicates a new type, to be set from 12 to 0 metres instead of from 0 to 12 previously. In the new type setting, the spring is only tensioned when the torpedo is in the tube. Prisoners stated that the new method of setting the depth from 12 metres downwards is more accurate.
A red bar on G7a, torpedo indicates that it is not to be fired with a speed setting of 44 knots during trials, in order to preserve its mechanism.
A prisoner claimed some knowledge of the red and green markings on torpedoes. He said that the markings referred to the weight of the head, those with the red ring being stated to have the heavier head. The prisoner added that those torpedoes marked with a red ring would have as "verst

:( I can understand why some people find the emblems used in the Third Reich offensive. My Father, who is a Kriegsmarine Veteran has always concluded that Hitler and the Nazi were idiots even then. But I also feel it is doing the present generation a big disservice not allowing them to see and even allowing them to make their own judgements. Many young poeple (30 and younger) in Europe and the US don't even realize or care if there was a World War II. To them it is "ancient history" When I build a model of a German WWII subject, if I want a flag or marking on it, I put it on. It is "Historically accurate". If they don't like it, don't look.
To me I got the impression that the pipeplan shows an ordinary boardvalve with air connection for weedblowing. Se standard sketch below. As far as I can see(it may be wrong) there are only two valves connected to the valvehousing as usual the correctly marked ( with a ball) handwheel for the boardvalve and the smaller correctly marked handwheel for the seaweedblowing. This arrangement is on all vital board valves.
Christopher/ Maciek.
Maciek thanks for the answer. I having studied the drawings and photos a bit more and I guess the only right in my previous post is that I do not know anything about torpedoes ;D . Anyhow me being puzzled about seaweed blowing is probably due to the fact that I didn`t recognize the icon for the seavalve properly, it is not a suction seavalve (as for pumps) but a flooding seavalve normally not equipped with weedblowing (low suction). Normally the seavalve housing do not have any direct connection to other pipes, branch off is done after the valve ( except HP air for weedblowing) however this valve has indeed a connection for fineflooding instead of weedblowing. Below I have made a picture trying to explain my thoughts.
I`m not sure about the 2nd. extra connection you made on the valvehousing Christopher, as I cannot see it on the photo and it is unusual to have so many connections directly on the seaboardvalves. Again I am in deep water when I come to torpedo questions you guys know better than me.

Investigating the tubes, i have come to the realization that while nominally mirrored they cannot be exactly mirrored, as the torpedos are the controlling factor.
There are no port or starboard torpedos - so certain fixtures must be in the same place on each tube.
There are, however, port-side fixtures and starboard fixtures for the tubes. You cannot use all of the parts from one side to fix the other side.
This no doubt, increased the logistical load for the warehousing and mechanical people.
The pistons have keys/ears the go diagonally depending on the side of the ship they are on.
The aft torpedo tube on the U-995 seems to be closest to the portside model.
Unbelievable a third extra connection on a seaboard valve. This look more than a seaweed blow valve, leaving the other two in the dark. Could we guess equalizing line and steam? I really not sure.
Here is one more shot of this valve

Christopher, I believe we can verify this easily by looking at the tubes of the Type XXI and XXIII as there tubes I am sure are steel. We just need a few good photo

Maciek, I did not realise they werepiston-less. Why did they remove the piston system?
Thanks Maciek -
I suppose that defeats rather soundly my theory that late period tubes did not have the bulges - I just needed the right photo, and your two definitely show them. None of the ones I have had until now show a definitive bulge.
Good to know.
It does tell us one thing for sure - putting a string or a tape measure around them to get an external diameter will not be exact with the bulges in the way, but could still be reasonably close. We still need someone to find wall thickness with calipers. If only we new someone at Laboe!
I will continue to plod on...

- Detailed pressure relief hand wheel on breech door (A surprisingly difficult shape to construct in 3D!)(http://www.kabutographics.com/_VIICBuild/new3d006.jpg)
Excellent work Christopher, one note - this is not pressure relief handle wheel, but a handle wheel for spindle to adjusting piston postion (and whole tropedo) in torpedo tube, when breech doors are closed.Thanks Maciek! I MEANT to type Position Relief not pressure relief! One day I will learn to use a keyboard properly! ;-)

Wonderful work. Will you be releasing a 3d interactive virtual tour once you have completed the project?OldNoob -
Hi Gentlemen,Thanks Maciek - good information.
Being with torpedo tubes subject, I have updated my description of U-Boats torpedo tubes:
http://www.ubootwaffe.pl/en/u-boats/equipment/torpedo-tubes-of-german-u-boats (http://www.ubootwaffe.pl/en/u-boats/equipment/torpedo-tubes-of-german-u-boats)
The major update is section about heating torpedo batteries, but there are also several
minor changes.

The FaT drawings were quite useful. I will have to design torpedo tubes Pre-FaT (probably bronze), ones with FaT (Probably steel) and ones with LuT. Because I have the most pictures of LuT Mechanisms, I am starting with those, but if you have any more information or drawings on the FaT and LuT mechanisms on the Rohr I would appreciate it! :-)
I am also trying to find period drawings on the angle setting and firing mechanisms.
Questions -
... could a tube have both FaT and Lut mechanisms, and were they the same location on the torpedoes/tubes?
... do you know the frame locations on the Type VIIC/VIIC-41 for the ETO Heizkasten? Were they likely in the similar location you showed on the Type IX? I see the vibration shock mountings on the drawings at http://www.uboatarchive.net/U-570Plate34.htm (http://www.uboatarchive.net/U-570Plate34.htm) but I do not see those devices on the photos I have of U-995.
Five Electric torpedo heating control boxers, (ETO HEIZKASTEN). Of these two were mounted on the port side, and two on the starboard side, placed for use with torpedoes loaded in the bow tubes, and one at the stern for use with the torpedo loaded in the stern tube.
Surely she must have had the ability to fire electric torpedoes... "LUT-Versionen wurden aus den g
Well, no. The FAT setting gear consisted of two parts - one - regular gyro angle setting spindle - as in case of regular GA VIII, and FAT spindle, located in the area of overpressure valve (forward of gyro angle setting spindle). LUT setting gear consisted of multi-spindle gear located in place of regular GA VIII gyro angle setting spindle. These two mechanism could not be built at the same time.
I notice in photos of U-995 there are several shock mounts applied to the inside of the druckkorper between D.Spt that could be where the heating boxes might have once been mounted.
For instance, betweend Sbd. D.Spt 75-76 near the box with the four torpedo lights there is an obvious mount for something about the same size as what we are looking for...
and there is another set of mounts similar, below the manual lube-oul pump Sbd. Dspt. 74-75, near the flow meter.
There are also mounts that had something removed on the BB side above the flow meter quite near electrical switch boxes.
We must still find what the 45 cm x 33 cm mounts near the (post-war) electrical switches. They are an enigma (pardon the pun), as are the (post-war) switches themselves. The underside of the lower set of electrical boxes (painted sloppy dark gray) seem to be of a sort that might allow for something portable to be plugged in to them at the bottom. It is a continuing challenge to figure out what was "period" and what was post-war additions.
What you say about the low mountings by the flow meters also makes sense. I do wonder what pipes used to be mounted there, and why there are not mounts of a similar nature farther forward.
We must also remember that there may have been equipment mounted where the door was cut into the side of U-995. I rather doubt that it was a blank, clean bulkhead.
