German Type 212A 3D Print Build

[rwtdiver]

I found this closed cell foam on Amazon,

https://www.amazon.com/Foamzz-High-Density-Panels-Closed-Cell-Insulation/dp/B0BNP4D39T/ref=sr_1_4?adgrpid=12281548

Would it work for sumarine floatation?

Thank you DrSchmidt,

Makes me I wish I could go back to school and studied my German a little better! :-)) Great video non the less, and it certainly gives you some idea what the crews of the 212 submarines go through, also some great shots of the submarine itself. This will all help when the finish work on the 212 A comes do.

That above is another excellent video, Thank you. I get the sense of the pace and life on board during heavy weather.

here is a frame from the video showing detail of the starboard sail navigation light. Might be useful. It looks the same on the Dolphin subs too (both built by HDW). Hope it of some use. The subtitles says 'The position lantern 10 CM Plexiglas.'

Steven,

Thank you for posting the great video. Some really good input into the 212 class boats.

Thank you Bruce, I appreciate the information.

I have looked on amazon and I believe they handle the closed cell type foam. Thanks again.

I have been working on the control linkages for the 212, which are quite complicated for the uninitiated builder. I emailed Bob at Nautilus Drydocks and he lead me to his build of the 212 A boat

https://www.rc-submarine.com/product-page/german-type-212a-full-package-in-1-72-scale

And the diagram of the 1/16" control linkage was on this site.



I reduced the photo of the diagrams down to 55% and 60% which seemed to be the same size as my "Z" bender makes. with this information I am sure I will get it real close.

SPECIAL NOTE: To those of you that are wanting to get into this hobby, you will not find a better source anywhere than Nautilus Drydocks. Check out his store, and his 100's of informational
YouTubes. Also this forum is the best for information and people that are willing to help you...

Thank you this will be a useful analog in the German Israeli Dolphin 2 x stern set up too. same design and radio to program. Timely.

The Type 212 A's are very small subs as subs go. I saw a German You tube documentary on the boats. The fighting abilities are remarkable, but the crew is cramped even for a submarine.

They said in documentary the cook is only member of the crew that can't be covered in duties by other crew members There is just one cook, and the poor guy serves 4 meals a day. breakfast, lunch, dinner, & mid watch. He cooks in 6-hour cycles, cook has no back up, only member t of the crew like this. Cooks 3 hours - sleeps 3 and then another cycle. The future larger 212 CD will be a huge plus. Surprised how much sodas and sugar candy the Germans consume. This common?

This afternoon I followed up on the prep work for the linkage horns.







As the photos show, each brass horn had to be hand filed and shaped to the so they would fit into the stern section and not rub against the side of the hull.

Now we need to bend the wire linkages.

You need closed cell foam board or sheets, I usually pick up at Home Depot for cheap, not sure if amazon has this

Question:

Now that I am starting the build on my 212 boat, I will be needing foam blocks for the trimming process. Can someone (Hopefully amazon) tell me where to find and what kind should I be looking for? I used to get it from Nautilus Drydocks, but Bob no longer carries it.

Thank you for the help.

The hull printing work is moving along.



I am a little more than half way through with the bottom sections.

Making some headway on the stern section of the 212.



I installed the 3/32" brass tubing for the bushings to support the 1/16" brass rods for the rudders and dive planes.



I just stuck the rudder on to see how it was going to fit. I will make further adjustments to reduce the gap and set up the alignment..

Got in some early morning soldering work done.



I have manufactured 4 brass control horns for the rudders and dive planes. I still need to drill the holes in the arms for the control rods, and ounce I have the holes drilled,
I will then finish the shaping of the horns.

[rwtdiver]

Tonight I decided to get started on some of the more complex parts to the 212 build.



I printed out the stern section and the rudders/dive planes. This is so I can get started on the control surface linkages. The stern section controls are in a X configuration which makes them a little more complex to fabricate and install.



The control linkage will required 4 interior horns for the control rod connections. I will be fabricating them using brass bar stock and 1/16" collars.

I'm rellay looking forward to the next generation of the 212 class, the 212 CD (common design), that will be built together with Denmark. Wit 73 m length they will be much bigger and powerfull.

DrSchmidt,

I found this photo showing a comparison between the 212 A and the 212 CD that you referenced.



The size difference is amazing! Thank you very much for posting the information..
