#55006, "RE: Titanic 3D model project"
In response to In response to 0


          

Hello.
I've finished with the reciprocating engines. Lots and lots of changes. I followed many of Bill's suggestions (Thanks). Added the rest of the plumbing, baring and rev gear valves and too many other tweaks to list here.
It is easy to keep going as it is never "good enough" so I kinda had to come to a final stopping point.

Below is a couple last photos in the test room. I am all done with the engine except for the auxiliary blow-off valve and associated wheel which will go on the port side. The plumbing is installed (Thanks Bill for the schematics posted elsewhere). The small pipe sticking out straight forward and parallel with the HP input is the aux drain for the Rev gear, the "L" shaped pipe sticking out amid ship then turning forward (Superimposed over the HP input pipe) is the connection for regulated steam. The pipe running from under the IP cylinder down the Y column to the floor is from the drain cock valves to the (supposed) port hotwell tank:



Shown below is the piping and control for the baring gear. Also the forward drain cock pipe to the (supposed) starboard hotwell tank:



One easily missed change is the new drain cock valves. They are now bolted to the cylinder bottom and their actuating rods follow the proper upward angle up from the bottom, according to the Britannic forward engine view:



When I mirrored over to port and put them into the reciprocating room model, it was surprising how much bulkier these engines are than the previous version.
These are built with the Britannic side and front view backdrop and Titanic cylinder head top view. They are really and truly a monstrosity!

The necessity of the skewed position of the engines became more apparent as we'll need the additional rear space for catwalk stairs. There's not all that much room for the stairs between the exhaust LP big-end pipes.

Each after end is rotated 1 degree outward. I didn't take any actual measurements between the port and starboard frames but 1 degree seemed to be enough. I bet it would also put our propellers at or near their proper spacing (If they were to be made).

Speaking of stairs-
When I did the previous catwalk stairs, one obstacle discovered was getting around the inter-cylinder I beams. To create enough headroom for someone to ascend-descend without clobbering their head.

Here the crotch I-beams (I know there's a joke there somewhere) are installed which will pose more of a challenge for stairs.
This room is filling right up. The necessity for doing a 360 view is more apparent.

Notice how much more light is admitted through the forward casing to Boat deck. The operating area of these engines become more apparent here. The room seems to be getting smaller.
The valve gearing,main rods etc are now in their proper place. Still trimmed to full forward:



I'll probably mount two telegraphs onto each Y beam column, the same one which has the drain cock plumbing:



Each reverse gear has two cut-off valves:



You can see how really BIG these monsters are in the ariel view:



I did a few 4K renderings of these. Wow about an hour to render one frame (on an Intel i7 octo core). A 1280x720 resolution is about 12 minutes each which is more manageable. Radiosity is set to 12 bounces. Volumetrics is also possible, which adds "Thickness" to the air (as if observing light beams in front of a window) but multiplies the time by a lot. I am currently at 1,389,929 vertices and 96,101 polygons. Fine for photos and cinema but this would have to be redone for any gaming purposes.

I have the room plumbing worked out for the supply steam and I'll post the plan later. Also began planning a 3D printable model. You'd be able to download the files and print them yourself or send them off to a printing company like Shapeways.

A couple questions if you don't mind. I've done a lot of telegraph research and there doesn't seem to be much of a standard one style to the other. You google "Titanic telegraph) and the sort to find endless styles.
Does the one below seem a likely model candidate with its STOP,STAND BY,DEAD SLOW,SLOW,HALF and FULL markings?

Also for future references, does anyone know the engine RPM targets for those speeds? I believe FULL with a full head of steam would be 78 RPM.

Thanks and enjoy,
