When one looks at above pictures one could believe, that the stern torpedo room is done....well, not quite. The complete lower half of the pressure hull and the t-frames are missing. Also the section below the torpedo tube, where the stern trim tank was located, was wrong. So I altered the back part to resemble the trim tank and added the lower pressure hull with the frames. Tedious job, but finished it looks quite good.....well, despite the backside. I also added the torpedo loading tube, which was missing in the kit, too.

Indeed, indeed.....

And complete with the stored extra torpedo. In the kit the torpedo is just sitting flush on the floor with no fixation. Kinda bad idea with a boat roling in heavy seas. So I scratch built two bases and tied the torpedo down with styrene wire. Looks better me thinks ;-)

Flappy torpedoes would affect stability somewhat as well as ruin their accuracy if the internals are knocked about too much.

And I guess it wouldn't be great for the interior of the boat when a 1,5 t Torpedo bangs around.....

Progress is slow as there are many little things to do that require some time. E.g. the hatch and of the rear torpedo tube is missing as is the parts of the hull where the torpedo exits the boat. I shaped this using glass fiber and made the hatch from resin. I also started to modify the outer sections that go into the stern, e.g. dive bunker 1. Lots of fitting, modifying and whatnot. But it comes together. I will make a real cut away boat, so I'll cut the transparent hull and the stern section open. To do this properly I already glued the stern section to the starboard transparent forward half of the hull. Assembled that thing looks "xxxxx" huge...compared to a 1:72 Revell VIIc

O.K., and with cut oprn hull. Need some minor adjustments and some small repais where I got to brutal, but all in all, I'm quite pleased with the look....

That is a seriously impressive display piece. Looking forward to how this develops :-))

O.K., still slow progress. Mainly because I had to rebuild the aft dive bunker 3 times. Ripping of styrene, putting on new sheets in a new configuration. reason was, that the bunker has an intricate shape, that I had problems figuring out from the drawings I have. But now I guess is pretty accurate. The bunker has a dome like shape with the bow end splitting into two sections that sandwich the rudder lever (to which the drive shafts) for the rudders are attached and the spare torpedo compartment.  The two bottles for compressed air rest on these sections, angled upwards. I also put in the blow valve for the bunker and the corresponding mechanics. I also added the drive shaft for the aft torpedo tube hatch and cover. What is still missing is the electric drive for the rear dive planes, it's drive shaft and the deflection mechanism that connects it with the planes. But I'll have to think a bit how I'm going to make that.

Again small progress. I decided to add the actuator for the rear dive planes. You can see it in front of the stern torpedo tube. It's basically an electric motor with a gear box and a push rod driven by a thread road. The thing is pretty much the same thing than the one driving the rudders. Modeled in CAD, 3D printed, painted......
