yvesvidal Posted December 19, 2019 Author Share #484 Posted December 19, 2019 (edited) 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.

yvesvidal Posted December 20, 2019 Author Share #491 Posted December 20, 2019 (edited) 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?

I scratch built a replacement stand using plastic sheet and rod and bits of the PE. I like your idea of using component leads though - I wish I had thought of that 🤔 - it's a lot easier! I'm guessing that this was a maintenance/repair bench. The cylinder may have contained oil, or was a heating element. The vertical pipe should go up to the deck head so it's fed from something above? PS. A word of warning - when you fit the deck head (ceiling) you may find that the fresh air fan mounted from the bulkhead hits one of the boxes on the deck head. I rectified this by cutting down the shaft on the right-hand side of the fan and re-attaching to the pipe. popeye the sailor, hexnut, Canute and 3 others 6 Quote Link to comment Share on other sites More sharing options...

Ink was very much a part of maritime life. The Disbursing Officer had a knock-down desk with a double-acting drawer that was set up where appropriate. The Pay Book, showing earned pay and all debits against that pay listed out, per sailor. The Sailors, each in their turn, then approached the DO who pointed out the amounts for the concurrence of the Sailor. The Sailor then "made his mark" in ink, in the paybook. The DO placed those funds paid out on his side ofth drwaer, and the sailor then opened the drawer from his side and drew his pay. Since pay might be in specie or bullion, this is why the Disbursing Officer, at least until electronic debt/debit cards were introduced, wears a side arm as badge of office on payday.

Blue Pilot Posted December 24, 2019 Share #503 Posted December 24, 2019 Amazing, I wonder if they were prepared to do that kind of heavy maintenance at sea or did they cary spares like that to have on hand for after they limped into a shipyard? Long ago as a C-130 First Mechanic we carried spare parts but nothing that would require special lifts or cranes. I can only imagine looking at that piston the size and weight of the engine head! Even simply changing the piston on a car is a big job so I am guessing if they carried this as a spare it would be for use in a maintenance facility or am I wrong? popeye the sailor, mtaylor, yvesvidal and 3 others 6 Quote Mark Current Builds: 18th Century Merchantman 1/2 Hull Smuggler Pride of Baltimore II Gallery: Yankee Hero Armed Virginia Sloop Future Builds: Rattlesnake, Fair American Link to comment Share on other sites More sharing options...
yvesvidal Posted December 24, 2019 Author Share #504 Posted December 24, 2019 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.

yvesvidal Posted December 25, 2019 Author Share #506 Posted December 25, 2019 (edited) 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.
