Realised after so long that i did find it and post it to Aaron some time ago. It's too big for this portal, so if anyone still wants it, let me know your emaili address and I'll send it. Unless a moderator can tell me how to upload it to the site as a library document?

Hi Codad, I too am thinking of making a live model. Your plans sound v. Interesting, could you please send a copy to [email protected] please! Cheers, Sec'

Hi this is my first post here and as the last post on this subject was some time ago so hope you all see it. Steve love what you have being doing with the 3D it is really cool and the time it must have taken is quite a commitment i take my hat off to you my friend. I am trying to build a 5% scale model of this engine that will run on steam, already have 3800 hours into this build and i am generating more questions than i have answers to. I am working off the French/metric drawing which is really bad quality but did not realise there was a English dimension version which has more detail and better quality where can i get a copy Help, Help, Help? Please.
Sec you posted a picture of the end/side view of the engine which was really good quality where can i get a copy? This picture has helped me the oil feed pipe connected to the bottom of the cross head had to be able to change length and in your picture you can see the telescopic section clearly however its position below the cross head probably means it was not oil for the cross head but was piped down the connecting rod to the big end bearing and the cross head was supplied from somewhere else? anybody got any ideas ?
Does anybody know where the oil supply was attached to the cross head slide plates? there appears to be a hole at the top of the machined oil grooves but where was the pipe connected to it? picture attached.
Does anybody know where the cooling water connects to the cross head slide plates? the only possible connection point i have found is what looks like a round bolt flange at the bottom of the slide plate (picture attached) however this is where Steve has the lifting beam attached and after looking at hidden detail drawing i am inclined to agree. So where are the water connections?

Steve once again terrific job with the 3D thanks for posting and sorry if this is not really posted in the right place.

Hi Griffon, amazing, your model looks great so far.
I'll go through the other photos I have and post anything I might have that'll help.
Regarding the telescopic pipe, I think this would have been for the X-head pin. They were telescopic pumps, so simple non-return valves on the inlet mean oil is forced into the bearing as the pipe length shortens. Clever! Also the oil pot would be too small to feed the big end as well IMO.
You talk about Xhead being water cooled, is this a design feature of the Olympic class? I've not heard of it before, even on modern 2-stroke marine diesels. Properly lubricated, the slides don't make much heat, the size of the slides should conduct away the heat ok.
I know there's a forced lubrication system for the turbine bearings, I'll look if it may also to the recip engine crank bearings.
Searching photos and plans for anymore info now about that.

Found this photo 'attached' of the Brittanic. It clearly shows the troughs under the Xhead slides, so I think it likely they were lubricated as someone mentioned earlier by a dip in the trough then smears the slides. Typically a oil/water mix to get optimum cooling and lub.
The photo also shows pipework feeding into and out of the main bearing by a forced system. Maybe a pump or simply a gravity tank

This photo is of Titanic's engines, 401, shows nicely the different shape oh the LP cylinders' slide valves. Hope it's useful

Hi Sec thanks for the photos they are much clearer than the ones i have and will really help. Just started work on it again other commitments got in the way so you timing is perfect and confirming the cross head connecting oil tubes were pumps is a big help, one less thing to bang my head against the wall about
Thanks Brian

Glad to be of help Brian,

I found a wealth of photos on the Ulster museum's website. It takes a bit of searching but if you put in each ship's hull number in turn and search through they have all photos in Harland and Wolff's collection. You can buy prints or view/save high definition copies of them.
Link: National Museums NI

Fascinating to look through and helped me a lot piecing together the puzzle, just watch those hull numbers! Best if you can see them painted on parts in the photo for a true guarantee.

Thanks very much for the photo.
Having the workers shown in the photo shows you a better idea of how huge these things were.
If I blow up and enlarge " the bloke in black on the ladder " he seems to be transparent..... you
see right through him.
A ghost ???
The ghost of Thomas Andrews ????
It is MOST eerie !!!l

My apologies to the Moderators and others for the repitition
but curious if anybody else has noticed the curious transparent ",bloke in black " and has an explanation ?

These are glass plate negatives, with the old photos if anything moved for the seconds of exposure it would appear transparent and 'ghostly'!

The light behind him probably added to the effect

As an aside, and as close as one can get to a steam engine of that size and similarity, still in operation, is the one at Kempton Park..

This is amazing! Can i ask that you finish the top of the casing and have 360 views inside of the casing?

Hello, sorry I haven't visited more often.
To answer some questions, almost all of the drawings I used for reference are either available on the web or from my main source of a pair of books "Titanic the ship Magnificent".
I used volume 1 a lot as it covers old practices of ship construction used on the Olympic class ships, machinery etc. Web sources like the Britanica and other reasonably reliable places. I also relied on the advice and suggestions from historians, sailors who worked on and engineered the older but more modern steam powered ships.

I was given a few proprietary images which covered plumbing and ventilation plans from the 1930 Olympic refit but all others were found in the public domain.

Some aspects of the images I made are definitely Titanic specific but most are a mixture of all 3 Olympic class ships. A few things (but not many) are educated guesses like the appearance and placement of the main steam board.

It took about a year for me to do the reciprocating engine room and boiler room #1.

I have 3 old computers still rendering 24hrs a day making a HD walkthrough tour of the room on all levels. They've been rendering (more or less) for about a year and about 3/4 done.
I also plan to walk through BR1 from Scotland Road afterwards.

Hoping to have this project rendered and wrapped up mid 2019.

Thanks for the kind words!

Hey Steve, I visited your YouTube channel and there are many subscribers but no content. Did your walkthrough renders not work out? I just got into 3D modelling the Titanic, and missed a lot of great discussion so I'm combing through archives upon archives of old content trying to learn as much as possible before resorting to asking questions that may have been answered already.

The next Kempton steam up for the worlds biggest working steam engine is due 19th - 20th March 2022. Subject to a replacement bevel pinion gear after 90 years of operation. The gear is made after a year to find a manufacture who could make the correct gear to match the crown gear. Its in the long progress of been ground and lapped in, with fingers cross ready for March.

Amazing detail, I can see ever rivet and pipe.
