What a terrific collection. You Sir, love planes. Yves -
Merry Christmas to all and my Best wishes of Health, Love, Friendship and modeling passion for the New Year. A few updates on that Christmas day. The Diesel engine compartment is now completed and the pressure hull has been installed. The two pieces of pipes for the exhaust as well as the fresh air ingress pipe have been glued and sanded flush with the bulkheads. I have added an extra air tank on the pressure hull, tanks that were used to crank up the diesel engines. The electrical wiring has been completed and verified. We have four white LEDs in series, requiring close to 11 Volts to illuminate. With an adjustable resistor, I will be able to harmonize the intensity of the light, with the other compartments. The current is about 3 mA. The LED above the wood desk is a micro-LED and provides a more classic and yellowish color than the ceiling lights. It is now time to insert the module into the hull. Again, at this point, it is difficult and delicate to go back. The existing wires are carefully inserted in the slots provided by Trumpeter, on each bulkhead. The module inserts in the rear compartment, through the torpedo recess and two large pins, hidden by some apparatus. The module is only glued on the front bulkhead. Closing the starboard hull, this is what we will be able to see: You see the importance of creating the side tanks openings: And a couple of pictures for the claustrophobic's: Folks, I have reached a point where I have two modules to build and countless details to finish on the deck, conning tower, guns and on top of each module, when visible. Some electrical work needs to be completed, as well as some paint touch-ups and light weathering in multiple places. I will finish this model but have decided to take a little break from it and tackle instead one of the two projects I have at heart. One of them (there are many...) could go in this forum as it is boat related. The other one, not being something that floats on water would have to be developed in the "Shore Leave" section. Whatever is being done, I will provide a link to keep you updated. The Type VIIc will be placed back in its box (yes, the fully assembled hull fits) and stored for a few weeks or months. I wish you all Happy and Relaxing Holidays, and passion, fire and energy for many projects. Yves

I suspect that this kind of maintenance could not have been done at sea. This is just a way to show how the engine was made, the sheer size of the cylinders and to allow the observer to see the complete engine in the background. It is a model and not a representation of how it was used during a sea patrol. Many thanks for all the "likes" and support. It is very motivating. Yves

The crew is in place, around the diesel engines. It is the last piece of details on this compartment, before sealing it with the pressure hull. A few pictures.... Everybody is very busy.... Let's enjoy all these perspectives, because it will not be possible again, when the pressure hull is glued on top. Yves

You may not be good with computer, but you build superb models. Yves

Beautiful Model Denis. I love these barnacles stuck to the piles.... Are you going to model some water and light waves, too? Yves

Don, I have read some publications from Maciek. Thanks for all the good info you are providing to this thread and for your fantastic book. Yves

We now have reached a point, when serious decisions must be taken. Assemble or not assemble? I am sure you all agree that it needs to be put together. Therefore, here are a few pictures: And the silly pictures... I hope you have enjoyed being reduced to 1/48th scale and taking a tour of that interesting compartment. Next time, we seal it with the ceiling..... but first some crews.... Yves

Moving on with the walkway. Basically just a few parts according to Trumpeter, but a nightmare to assemble..... That table made of photo-etched parts is ridiculous and a challenge to the nerves. You can see the result of my assembly on the picture..... a disaster. Sometimes, it is good to show the casualties of modeling, as most builders only post their success: Trumpeter should have offered a table made of plastic parts and it would have been so much easier to assemble. instead, I decided to do mine with the "legs" of electronic components, bent and inserted in the walkway, after drilling #60 holes. A lot easier and so much sturdier. Quite realistic too: When all is painted and said: I have no idea what this table is used for. Is it used for mechanical jobs? Don, can you chime in and enlighten us? Yves

Don, you truly are the expert. I may have to change it.... I am sure the rivets counters will argue with my choice..... Yves

Most likely, I don't think they had ball pens yet and I doubt they used fountain pens inside a submarine. Yves

Still toying, yes literally, with the front bulkhead. I have decided with some spare parts to replicate the fan system, used to bring fresh air and extract used air from the inside of the pressure hull. Of course, Trumpeter does not provide the second set of fan/turbine as well as some of the pipes and it is very regrettable. It takes a lot of butchering and gluing of the pipes to get to a decent and matching results. I have also added the electric motors which are driving the turbines, as these parts were not designed by Trumpeter. Please do not ask for the electric wires of the fan motors.... Close up on the little wooden desk. Barely visible against the wall, is a German print indicating essential operations of the Diesel engines. On the wooden desk, is a schematic of some of the numerous pipes circuits and a large pen. Not yet visible, is a small light to the left of the red control hand wheel. The micro wires are coming above on the bulkhead. We now have quite a few pieces to put together. However, before the final assembly, I still have to work on the walkway. Yves

Thanks Don for these complement of information. Obviously, Trumpeter did not know about these peculiarities, or decided to skip them. Yves

I have been working on the exhaust system of the Port diesel engine. Most of it will be completely invisible, but I have the satisfaction to know that it is there.... First, the ceiling had to be slotted to allow the fixed exhaust pipe to go through. In fact, it is almost impossible to present the piping correctly, if you plan to use the hole provided by the kit. Below is a picture before: And after: The right hole will be used to insert just the elbow, from the top, and as such does not need to be slotted. The exhaust is built by carefully gluing the pipe to the ramp: The tube is coiled with some heavy cotton thread to simulate the insulation band, that was used to insulate against the noise and heat. Finally, after gluing in place the exhaust: Most of it is frankly invisible. So, let's enjoy it as we will never see it again, once the ceiling is installed. Yves

We are coming soon (hopefully) to a conclusion on the Diesel engines compartment. I am now working on the front bulkhead: The bulkhead is cut on the starboard side, to show the various tanks, since this section will be visible from outside. And to make sure that the rear kitchen bulkhead matches that one, we cut them together: And then, it is the delicate assembly and endless touch-ups with paint, to make it look decent and realistic: A few more details, a light above the desk and we will move to the walkway assembly.

Enzo Ferrari by CDW - Tamiya - 1:12 Scale - PLASTIC
yvesvidal replied to CDW's topic in Non-ship/categorised builds
I have the McLaren F1 from Model Art. This is not a kit, but is at the same scale as your Ferrari. Made of metal, plastic and rubber parts. I bought it in Europe about 25 years ago, when the car came out. Yves

To stay on the subject of the Diesel engines used in the Type VIIc vessels, it is important to note that these motors could turn in both directions. Switching from one direction to the other did not take much time and could be done in less than 30 seconds by seasoned mechanics. The reversing mechanism was cleverly designed and was controlled by a single cylinder on top of each engine: The control was done from the front of the engines and the following drawing provides a detailed diagram of the mechanism: Finally, these engines had rather fragile bearings. It was not uncommon to have to replace them during a cruise and trained mechanics could do that daunting and extremely dirty task in a few hours. The movie Das Boot depicts such intervention being done: Mr. Tore, the expert who navigated the U-995, recounts in his memoirs how delicate and tedious it was to replace one or multiple crankshaft bearings while navigating.
