This is a quick update on progress. Having done the animation test - which has many technical issues still to be sorted - I wanted to do something that felt more like a big step forward, so I've started on the Y-Frames.

Latest rendering of the Engine. Nothing new here - I haven't had time to do actual work for a few weeks, so excuse the dodgy animations - it's just better visuals...

This is the latest update on progress...the project has slowed down considerably due to pressure from other projects, not least of which is the Bow wreck I'm scratch-building. This latest set of images shows the correct configuration of the central Y-Frames (which supported the High and Intermediate pressure cylinders). Also included is a shot of the Flywheel at the aft end of the engine with more accurate detailing.

Hi All...it's been a while since I last posted here on the Titanic Engine Build I'm working on. I've made some useful progress - The linking spans between the Y-Frames are now in place, with the Frames themselves now finalised. The Weigh Bar with it's support arms have been added, though the bar itself will undergo further modification as components of the reversing gear are added. The Worm Gear for the Barring (Turning) Engine at the aft end - next to the Fly (Bull) Wheel has been added and most recently, the Drainage reservoirs - Steam Traps - which carry condensates (water, oil) from the Cylinders have been added though connecting pipes are not yet made.

Hi Cian,
Do you have the original drawings of the engine to show the external sizes in feet and inches. Total length, width and height. If so please reply.

Hi Mike, I don't have original plans as such, I'm using a combination of photographic data and the plans found here - Plans
These are for the Britannic, obviously, so there are differences (Particularly with the Low Pressure Cylinders - Britannic's low pressure cylinders were primarily a single casting, with the cylinders and valve steam chests as a single unit, whereas with Olympic and Titanic the Valve gear steam chests were a bolted-on separate cast)...

This update shows the re-animated engine in action. Previous versions were tests to figure how to rig the beast and while this is not yet final - I'll probably find ways to further reduce separation of moving parts - I think it's close to finished. The Port Engine is seen here running at between 72 to 75 rpm, approximately full speed for the engine, and running in the Ahead direction.

Latest update - I've begun construction of the Browne's Reversing Engine...

More progress on the Reversing engine...It's tough work, with the available plans being somewhat difficult to interpret for a non-expert like me. Often, photo's of Britannic's engines help to shed light on things like this and while they have been of some help, there are fairly big differences between them and the plans (assuming I'm making a reasonable interpretation of the plans).

AWESOME!! Keep up the fantastic work!!

Latest progress on the Reversing Engine for the Titanic's Portside Reciprocating. This is proving to be an extremely difficult task, far more difficult than I would have expected. Reference for it is limited as I've mentioned before, so I have to try and navigate the differences between the Photographs of the engine and the available plans. The large drum at the back of the engine, which I believe is an oil reservoir for a hydraulic backup system that could be used in case the steam supply to the engine fails or is interrupted seems to also double up as a bracket which attaches the Reversing Engine to the adjacent Y-Frame (column) of the Reciprocating engine. The problem for me at the moment is the nagging feeling that there's probably error creeping in.

Outstanding work Cian, that looks excellent!

Regarding 'error creeping in' I guess you can only do the best with what information you have available.

Decided to test fit the Reversing Engine to the Reciprocating Engine in the main scene. Texturing and unwrap are not complete, so you will see some oddness there, but otherwise most of the main elements are in place. There are still improvements and additions to be made, it's not precisely placed relative to the engine, but the 'test fit' in the main scene works fairly well.

Hi folks, I've added a new video to my youtube channel showing progress on the engine build. Given that I've been extremely busy in work over the last few weeks there it shows essentially what was in the still images I posted a few weeks ago. Apart from 'unwrapping' the Reversing Engine for texturing and some piping (I'm assuming part of the oiling system) to the Piston rods, the video just adds to the progression on my channel. One little nugget though...after several requests, I've attempted to add sound. I'm not a sound engineer, so it's amateurish and frankly, I have no idea if it's remotely accurate

Your doing a really good job on this. Not as big as Titanics engines but the vid below is of an triple expansion engine room and the sounds it makes. Your sound choice doesn't sound too far off. Again good job.

I have been on the SS Shieldhall ship three times want a fantastic experience you get on how the triple expansion engines work as used in Titanic, although on a on much smaller scale but the principal of steam is the same. The telegraph message from bridge to the engine room telegraph is very much the same as in Titanic to. The only main different is oil been used in the boilers and not coal. The temperature of the oil fired boiler room is over 100f as in Titanic can be as high 120-140f, and back breaking shovelling coal into the boilers. Even the bridge is some thing like on the Titanic again on a smaller scale. All those lovely polished brass work and varnish wood work. The steering gear is very much the same principal as Titanic to.
I would recommend a trip to anybody and the ship is still running to day, but with covid-19 restrictions.

I would like to see that engine. I like engines so it would be a treat for me. Would also like to see the SS Jeremiah O'Brien liberty ship engines also. But will have to wait till the bug thing is over as traveling is not fun right now. 100* F doesn't sound that bad. That was spring time where I used to work.

Cheers Mike, Cheers Steven... That is an excellent vid. There's a ton of info in there, great find...
