Worked a bit on the galley....details on the cuppoards, the sink, manholes, and feedthroughs for the ballast tank inlet valves.

Found some time to work on the Type II CAD model. Here's a view from the torpedo room through the control room (with radio room on the right) and through the galley to the door of the machine room.

Worked some more on the control room of the Vesikko (Type II). Got the gyro compass, the machine telegraphs, the steering wheel for the rudder , the compass repeater and the periscope winch setup into place. I also put the periscope wells and the pressure bottles under the floor done....

Found some time to work on the inner details of the control room of the Type II prototype Vesikko. The ventilation air manifold took some time. Folks back then really were artists in bending intricate peaces of tubing art...the box at the bottom are the alkaline cartridges for CO2 removal.

More detail work on the control room.....starts to lokk like something:

I worked allot on the control room, so much, that I needed to take a break from it. So I decided to give the Diesel engine a try...and here's why I love the internet. Designing the Diesel just from photos is very, very hard and will always be inaccurate. So I went on the hunt for drawings. And guess what, the International Maritime Museum in Hamburg has the Construction Manual in their archives, an archive that was digitized and is freely available though the German Digital Library
-> https://www.deutsche-digitale-biblio...st&hitNumber=1
Had problems downloading the whole file, contacted them and they sent my the 406 pages book as pdf, I love it!
So here we go..as the Diesel will be tiny in 1/72 scale, I have to make compromises with diameters and wall thicknesses here and there, but it starts to look like the original:

More work on the drivetrain....
Diesel engine, elastic coupling, transmission, clutch and then the electric motor. The cilyndrical uright thing in thze back is the oil cooler for the transmission.

I did allot of work on the diesel and then started to model the engine room, starting with the engin foundations. The engine bases were a welded steel structure that also served as main fuel oil tank. I also added the foundations for the two thrust bearings and right in next to them (bow side) the electric motor clutch and the rpm-meter. The blue structure in the port aft side houses the toilet.

More details on the Vessiko engine room...

More progress on the Vessiko machine room and the additional stern room with four bunks, two compressed air cylinders and the feedthroughs for the control planes.

Getting there.....I'm coming close to the point, where aditional detail wn't be possible to add in 1/72 scale. But nt there yet.

Getting ready to start to uild the Vesikko with interior. So I'm ading the still missing piece, the conning tower:

More cables and pipes. Routing the pipes and cables on a curved surface in the CAD is time consuming. But the result looks good....

After the CAD models are almost finished, I started to build the interior of the boat, that s going to be placed inside the corresponding 1/72 scale Vesikko kit by special navy. I started with the bow torpedo room, i.e. with the torpedo tubes. I printed the whole assembly in one go, as I did it for the much bigger Type XXIII. It took me 7 tries to get this, very acceptable result. So much for 3D-printing is easy. When you operate at the limit of resin printing, every wrongly placed support can ruin a print....
Then I continued with the starboard and port haves of the forward third of the torpedo room. Tiny again, but actually better to print than the huge structural parts of the XXIIII.
First components, that were glued into place are the pressure bottles for the expulsion of the torpedos. Very good fit....
