atic: 1:35 Bronco XXIII with interior

[Fergal]

Brilliant stuff, please keep it up. I've recently purchased a clock that was in U 2336 and bought the Bronco model as well. There is very little available regarding the interior of the XXIII so this has been fab.

The torpedo room of a type XXIII submarine. The room was too short to fully pull the torpedoes from the tubes or to load them from inside. So they had to be loaded from outside through the muzzle doors and could only be pulled about 2/3rd of their lengths to service them. There were four foldable bunks on the port and six on the starboard side. Together with hammocks and mattresses on the floor the room could accommodate more than twelve people at once. On the port side there was a tiny galley with two cooking plates and an electrically heated pot right of them. Below the floor plates was the big battery that made the type XXIII together with the type XXI the first real submarines...

Progress on the Type XXIII submarine galley. Added the activated-charcoal filter for the fresh water faucet right to the sink and the respective piping. Additional work on the ventilation ducts and detail work on the electrically heated pot. Getting there.....

Working on the deep bilge pump of the Type XXIII. It was made by Klein, Schanzlin & Becker (KSB) an to my knowlege it was a two cylinder double-action piston pump with cross heads. With respect to how it looked....few information on that side. Tried to get info from KSB, but no answer. I know that in the stren room of the type XXI the same type of pump was installed, so I took it from there....I guess it's close but becomes guesswork in the lower parts.

Conning tower done....the wiring of the switches and boxes in the isnide is a but guesswork, but it makes sense. Sits comfortably on the control room....

[DrSchmidt]

Added the ladder and some junction boxes. Fixture for the lamp and cabling, the the CAD model of the conning tower for my 1:35 Bronco XXIII submarine kit is done.

Type XXIII submarine: That was a complicated one.....the cable pull mechanism of the periscope. The periscope was raised and lowered by a cable winch in the control room. The cable ran over various pulleys to the periscope. Intricate arrangement under the roof of the conning tower.

Conning tower. Hatch done, next attack periscope. There are plenty photos but all look differet. The XXIII plans help a little bit and I found some blurry cross sections. So what I show here is my best guess approxiamtion.

Thanks very much for posting the step by step progress on your CAD and 3D printed model interior. The level of research and effort that has gone into this project si very impressive.

Indeed one of the thing's of I've found very satisfying with CAD work is translating drawings, photos and often a bit of guesswork into a 3 dimensional model. As you note this often this takes a few iterations to get it right.

Out of curiosity what CAD software are you using?

[DrSchmidt]

Designing the hatches for my Txpe XXIII submarine project. Even with blueprints one can spend a few evenings to get them right...

Still designing the Type XXIII interior. Putting the finishing touches on the ventilation ducts and the ventilation manifold for the batteries. During charging the batteries produced hydrogen that had to be removed by the ventilation system. So there were four tubes running above the battery cells that collected the hydrogen though tiny tubes that were connected to the collection tubes. Tedious work....
