1:40 MASYU MARU This time we present the construction of the double bottom for the bow section blocks. This covers blocks DB-5 to DB-9. When assembled as one unit, the total length is 1.53m. The bottom shell plate will be fitted later. Furthermore, construction is proceeding without painting. All materials are 0.6mm thick cardboard. The construction process involves creating assembly drawings and component drawings using 2D CAD, printing them on a home printer, then cutting them out with a hand cutter and assembling them. This is a full scratch-built model. I will post it in two parts.

Absolutely amazing work!
I'm deeply impressed and speechless. -
1:40 MASYU MARU This is the stern structure. The rudder horn and shaft bracket support arms are also fitted as a single unit. As the upper deck is the steering gear room deck, the steering gear platform and hydraulic unit platform have also been positioned. The numerous curved sections suggest the Shell plate fitting work will prove challenging.
-
Oh my god, are you cutting all that by hand?
-
Dear Jan Hascherさん、”ありがとうございます” Thank you very much. The parts are cut one by one with a cutter knife as shown in the picture.

Hi Minoru Okuda,
that is the real art of paperwork...
Respect.Best regards.

Wow, simply amazing!

Awesome work

Incredible!

Cardmodelling like the original way of building a ship.
More than great.

1:40 MASYU MARU Construction of the bow structure. The deck surface is at wagon deck level. The two openings on the wagon deck provide space for the chain locker (anchor chain storage compartment).

Was für eine Wahnsinnsarbeit
-
Amazing!
The parts are cut one by one with a cutter knife as shown in the picture.
In Japan everything will be miniaturized. So there is a tiny laser cutter in the blade tip.

Allready the inner structures look like a work of art. How supreme will the finished model look like?
Ulrich
@ René: Surelya Minora uses a micro-waves cutter hidden in the cutterplade. For a laser cutter is to rough for this accurate work of art.
-
1/40 MASYU MARU This time, I made the 2nd deck on the stern side. Stern tube boss is also attached. I will leave a picture of the inside of the ship because I won't be able to see the inside of the ship when the assembly proceeds.

That can be called a shipyard......

Dear Mr. Okuda,
it's incredible. Every step of your construction process showcases true model-making artistry. I can only admire and marvel at it! Thank you very much for the presentation here!!!

Dear Mr. Lars G.さん、ありがとうございます。
I've been following your diesel engines with great interest; they are superbly crafted. I've also built the main engines (8 sets per ship) for the Masyu maru, so I'll introduce them. They are 1/40 scale models, with a total length of 107mm. They are four-stroke diesel engines.
Best regards
M.Okuda -
Very good!
My 1:250 scale two-stroke engine has a total length of "only" 60 mm. Smaller four-stroke engines are more suitable for modern passenger ships. Your completely self-built model features very detailed prints, as I can see from the engines. It looks fantastic, I like it very much!
Best regards
Lars

Hi Minoru-san,
I'm deeply impressed by your model (omoshiroi desu).
1:40 is quite a large scale. How Long will your model be at the end?
Dewa mata,

Dear noltingさん、ありがとうございます。
My model has now reached the stage shown in the photographs. (It took about four years to get this far.) When the stern block and bow block are placed side by side, the overall length is approximately 3.3 metres. I intend to take my time going forward and introduce the construction process step by step, so I hope you will continue to follow it without losing interest.
Best regards
M.Okuda

Das sprengt alle Maßstäbe!

Incredible!
Will you be able to move the model out of the room - if necessary - or do you need to take out a section of the wall?

Greetings

Dear Mr Okuda,
I am very impressed. As a marine engineer, I particularly admire the V engines. I look forward to gaining insights into your construction process, when you will continue with your great work.
Yours sincerely,
Cariño

... Please do give me a hand when the time comes.

1:40 MASYU MARU This time we introduce the second deck forward. The tunnel for the bow thruster will be incorporated into this block. The current model-building method involves constructing each block separately, fitting the shell plating, then joining the individual blocks to assemble the structure. We are currently focusing on constructing each block up to the wagon deck.
-
Great job, it looks fantastic

Do you hove a tip for a source to become the blueprints?

Best regards
Andreas

This is awesome shipbuilding...
How much cardboard did you use for this project ?
This seems to be much coardboard...

Dear AndreasJaegerさん、ありがとうございます。
I once worked at a shipyard. During that time, I gained extensive knowledge about this vessel. Furthermore, photographs of its sister ship being scrapped were published web. Using these as reference material, I spent several years creating the working drawings for this model ship. Therefore, I'm afraid I don't have any advice that could serve as a source of information. I'm sorry. My apologies for my poor English.
Best regards
M.Okuda
Dear O-Brianさん、ありがとうございます。
Approximately 400 sheets of A3-sized cardboard, 0.6mm thick, were used to achieve the current state.
Best regards

Kon nichi wa Minoru san,
a cardmodel in 1:250 will be fantastic, too. Can you imaging selling a simpler drawing plan in 1:250?

Dear Pianisto さん、ありがとうございます。
Many people are making 1:250 scale card models, and they are truly amazing. I am continuously impressed by how precisely they can be made at that scale. Right now, I am fully occupied with the construction of the 1:40 Mashu Maru, and I can't even think about the next project after finishing it. At the moment, it is still a blank slate.
Best regards

1:40 MASYU MARU This time we present the watertight bulkheads for the FR70 and FR53 engine rooms. Watertight sliding doors have also been fitted to the bulkheads. The section from FR70 forward is the No.1 Main Engine Room, while the section from FR70 aft is the No.2 Main Engine Room.
-
1:40 MASYU MARU Construction of the Side tanks (heeling tanks). As these tanks are present on both sides, symmetrical counterparts are being fabricated simultaneously.
-
1:40 MASYU MARU The blocks completed to date on the stern side have been provisionally assembled. The blocks used are the double bottom, second deck, heeling tanks, and watertight bulkheads. The shell plates will be fitted to each block individually after each block is completed.
-
1:40 MASYU MARU We have fabricated the watertight bulkhead and bow-side heeling tank, so we have performed a trial assembly of the individual blocks. The blocks assembled are the double bottom, heeling tank, watertight bulkhead, and the second deck on the bow side.
