A Challenge , I Think !

Sure, I have plans to do that with a 1/35 Italeri MAS Boat. Not cut away, but remove the deck. The problem is that there's not a lot of reference material, and the engines are large complex things that would need to be entirely scratchbuilt. I have a book on order per recommendation of Al Ross, but it's out of stock right now.

And it's been done. Speaking of, there was a Vanguard model that was opened to show a satelite. I remember building it, it was a big sucker.

I don't think Pop paid $ 599.00 for it...

Hi,

Although I probably don't have the time to do anything right now, your post got me thinking about some ideas. 

I have a 1/72 scale Revell of Germany 108ft Power Yacht, that has some interior detail on the main deck, that other builders have indicated is actually kind of hard to see once you put the model together.  That seems like it could be a good basis for either a "cut-away", or "lift apart" build, so that you can see the interior a little better. 

I have also heard that the actual yacht that the kit is based on has a stern "garage" for jetskis and other water toys, but that the base kit does not allow you to model that area as open, and provides no real detail back there.  So there may also be some potential there for maybe scratch building the doors open and adding some stuff inside. 

In addition, I'd love to maybe try and scratch build up at least part of the engine room, and show it through a "cutaway" opeining in one side of the boat.

Maybe some day.

Other than that, I've also seen a number of 3D CAD cutaways of modern diesel electric subs on the internet, and thought that it might be interesting to try and take maybe one of Revell of Germany's 1/144 scale modern German subs and try and make something that looks a bit like the mock ups that you see at trade shows, where alot of the interior parts are shown, but often parts of certain  systems are all painted the same, like shown below.

Tell you what ;

 Before you cut that Yacht . Do this . Get Lindberg's Coast Guard " Cape Class Cutter "

 Do what you want to it and this will be a less expensive alternative version . Besides the Walther Deisels look Kick Butt in there . You use either P.E. or Tichy Train Group detail parts for the walkways etc . 

 You use Walther H.O. train  Refinery kits for pipe and valve units . This will give you inexpensive training . The pipe sections to stand in for prop shafts .

 For the yacht , Write or E mail them and ask for brochures and maybe they will be glad to help . I am doing a ship that has all the marks and identifiers for a NUMA vessel . I got Mr.Cussler's E-mail Permission ! 

TB,

You've got a lot of good ideas .  Now you've got me thinking about an idea that I had a few years back when I first bought my 3D printer.  While surfing the internet one day I found a couple free 3D models of some medium speed marine diesel engines, and printed one out just to see how it turned out. 

I suspect that I could potentially mock up a notional machinery room for a generic modern ship around some of these free 3D models.  Fortunately we have a fair amount of marine engineering magazines and such at my office, so, even if I'm not actually modeling a specific vessel I might be able to make something reasonably representative of a typical engine room.

Dang, now I have another idea for my modeling wish list

Hi,

After thinking about it for a day, you got me to break down and order a 3D CAD model of a marine diesel engine, that I can print at home.

Maybe once I finish up a couple of the projects that I am working on now, I will start printing it in pieces, so that I can eventually mock up a notional modern commercial machinery room

Oy ! 

 Hey , that's great . But , It's a five . If you want bigger I suggest the Walthers H.O. Rail Diesels . They even come with the Generators . That one you show could be used for the gen set across the engine room .

The Transmission from a A.M.T. diesel truck turned on it's side can be your reduction and jacking gear unit . Thus a Turbo electric unit . Otherwise the Tranny from the " AllisonThunderBird " Drag car is perfect for a marine unit . Then connect your prop shaft to that . 

 I cheat and use a lot of other parts to pull it off .The results can be amazing ! Remember , if you choose to do the yacht , the engines I am talking about are 1/87 so they can be fudged into a 1/72 scale boat or ship . All you need to do is shorten the block and heads and associated gear mounted on it ! 

Hi,

Yeah, its only a five cylinder, but its a big 5 cylinder.  If you look closely you can see the railing around the different deck heights.  I haven't taken a close look at the model yet, but overall it looks to be about 3 decks high, so I'm suspecting that overall the full-scale engine would probably be bigger than my house .  As such I'm not sure what would be the best scale to use .

On a side note, here are some kind if fuzzy images of a similar project that I started awhile ago, but put on hold.  They show the parts for a 1/6 scale Chevy Small Block V-8 that I printed off a model that I downloaded off the internet.  Unfortunately I didn't check the transmission part close enough before printing it, and it got a bit messed up, because the shell was too thin for my print set up.  So it ended up with a lot of holes, and filler material.  In the end it the outer shell probably ended up just as much Bondo/Putty as actual plastic (or at least it seemed that way ).

Ay ! 

 Whattsa matta Fer You ! Thisa ting looksa good ta me , My goodness we needa youse in da gang dude . Nicea going ! Really , I forgot that many of the Marine applications are multi storied sized engines .Yes , You could use even a 1/25 Six as a multi storey engine in a 1/350 ship !

 My last ship had Wartzsilla Diesels that tall .Two full stories .Those were some of the first . I remember being somewhat overwhelmed when I first stood on the lower level and looked up at guys working on the Valves up top !

 That's why I stayed on the bridge ! You wouldn't ( well , maybe you would ) believe how much noise is generated by those things ! The Control Room had to be Sound-Proofed 

 Don't forget to include a cooling system too .This has through hull fittings for inlets and outlets  . Usually the manifolds and main exhaust have cooling jackets close to the engine as well .There are two types of systems .The dry which mean a closed cooling system and a wet which requires the exhaust be at the waterline .

 A wet exhaust was cooler as well . Now they would probably use Hundreds of gallons of DEF per day . I will never figure that out . DEF is urea based . So if you run out , does the crew provide the DEF ?

 All these systems that were liquid cooled to the sea used pumps so they would be near the inlets down low in the hull . All inlets are screened . As well as outlets .You don't want to suck sea growths or fishes  into your vessel's mechanical innards !.

Often there'll be a spare connecting rod, or even a crankshaft, built in to the engine room.

This is True .

     I remember seeing Rod and Crank parts fastened to lower bulkheads . The fascinating thing is that they could build an engine so big . Even being an engineer by choice , it still amazes me .

 Of course I went on to Buildings and Bridges and Levees ! Even more fascinating is the fact that I actually ran across an old freighter that had a four cylinder oscillating  steam engine and was still steaming . This while in the far east .

 This poor old ship had to be at least sixty years old then . But she was in surprisingly good shape and even was surprisingly clean . She flew the Danish Flag ! The crew was Phillipino as well . No one but the Third Mate spoke English !
