Shinpachi's 3D/CGI World

[Shinpachi]

Thanks javlin, Aaron, GrauGeist and vikingBerserker for evaluating my work.

There are so many excellent CG creators in the world!

I am not reaching to the research how much German U-boats influenced Japanese submarines yet but,
in my impression, it would be 80 - 90 percent.

Every Japanese engineers understood German before the war.
Even in 1970s when I was a student of a technical college, I was asked to learn German.

Interesting to know. Great work Shinpachi!

 

[Shinpachi]

OK, Aaron. Here is a historical record showing how IJN had contacts with the German U-boats.
Story must be back to 1918 when the WW1 was over and Japan was still a member of the allies then.

Attached image: page 3.
Translation of the page:

"Former German submarines
Receipt
Based on the cease-fire agreement dated 11th November 1918, an alliance naval meeting was held at the Ministry of Navy of the United Kingdom on 28th November and each nation (of the allies) was to receive the German submarines as the war trophies. It was decided on 9th December that the Imperial Japan was to receive the following 7 boats.
German submarines (7 boats)
U-125, U-46, U-55, UC-90, UC-99, UB-125 and UB-143"

Full copy of the original documents is also attached here in pdf file.
The 7 U-boats were exhibited, tested, researched by the Japanese navy( dozens of local makers joined research) and disintegrated several years later.

That's great information. I knew that some U-Boats has bases in Japanese territory during WWII, but I did not realize they had actually received some after WW1.

Here are photos.
From top to bottom: U-125, U-46, U-55, UC-90, UC-99, UB-125 and UB-143
They were numbered 1 to 7 (from top to bottom).

nice pics of the subs Shinpachi
keep them coming, your work is brilliant

 

[Pong]

Looks really great Shinpachi. Would love to see more 3D stuff.

 

[Shinpachi]

Thanks ellis995 and Pong for your favorable comments.

So, what I'm trying to make is I-400 based on I-14
Attached image shows the side section of the control tower of I-14.

Thanks for the info, Shinpachi...

I had no idea that the IJN actually owned some U-Boats, and some of those U-Boats in the photos looked fairly modern, too! Thanks for posting the photos and information!

Can't wait to see the progress!

 

[Shinpachi]

You are welcome, GrauGeist.
There are much more sleeping records when who visited the 7 U-boats etc in the JACAR library.
U-125 is said a direct sample for IJN I-21.

Thanks!

[vikingBerserker]

Nice!!!

 

[Gnomey]

Good stuff Shinpachi!

 

[Doughboy]

Nice work.

 

[GrauGeist]

This is coming along nicely...I can't wait to see the finished model!

 

[Shinpachi]

Thanks Aaron, vikingBerserker, Gnomey, Doughboy and GrauGeist.

Reading the manual I-14 page by page, I pick up measurement information to correct my modelling.
For example,

Diameter x Length of each tube:
Inner Main Tube(Hull) 5,800mm x 93,045mm
Control Tower 2,500mm x 6,830mm
Hanger Tube 3,650mm x abt.20,000mm

The center of Control Tower is located 5,050mm above the inner main tube.
The center of Hanger Tube is located abt. 2,900mm above the inner main tube.

Steel plate thickness is between 25 and 28mm
Water Pressure for Testing 2.5 ton per square milimeter.
Ribs are generally located 600mm apart.

 

[Geedee]

That my friend, is some very skillful work indeed ! . First class, and thanks for showing us what you can create.

 

[Maximowitz]

Remarkable work, very impressive indeed.

 

[Shinpachi]

I do appreciate your high reputation about my work, Geedee, Maximowitz and other memebers.
Thank you very much.

I must correct my last post -
Water Pressure for Testing 2.5 ton per square milimeter is wrong.
It must be per square centi-meter.

I can read Japanese but am not so familiar with the old Kanji(Chinese character) letters.
Sorry, gentlemen
