Does anyone happen to know the thickness of plating used on the funnels? This along with dimensions of the L beam that connects it the the deckhouse is useful. Oh.. Is anything known about the interior structure of them? And Not only the plating but I am looking at photos and even THG Renders and im having a hard time deciphering the layering of the plating. How did they go together?

Whenever I have been needing to do research I have been checking out ttsm from my library. I don't have copies if my own yet. I just found a brief description of the actual funnel plating in vol one so I am still looking for help.

I have based myself on the photographs on the web and the books: TTSM Volume 1 & 2 Titanic in photographs bY: DANIEL KLISTORNER, STEVE HALL, BRUCE BEVERIDGE, ART BRAUNSCHWEIGER, SCOTT ANDREWS "The Birth of the TITANIC by MICHAEL Mc CAUGHAN, ANATOMY OF THE TITANIC by TOM McCLUSKIE, TITANIC & HER SISTER OLYMPIC & BRITANNIC by TOM McCLUSKIE & MICHAEL SHARPE & LEO MARRIOTT AND THE BOOK: OLYMPIC & TITANIC & BRITANNIC AND ILLUSTRATED HISTORY OF THE OLYMPIC CLASS SHIPS byMARK CHIRNSIDE.
Thank you all. Sorry for all my spelling mistakes.

Thanks for the illustration. As I mentioned above, I have little information on the internal structure of the funnels so I can't agree or disagree with your interpretation.
Going by photos and the 'Engineering' plans, the lower funnels (i.e. the portion of the funnels between the boiler uptakes and the deckhouse roof) appear to have 10 radial plates, or distance pieces, between the funnel and the casing. I don't know if this was the case for the connection between the inner and outer parts of the upper funnels. Another consideration is whether the inner and outer parts were rigidly connected or if there was some provision for expansion (the inner funnel presumably being much hotter when in use).
These comments of course apply to the working funnels; funnel number four would be quite different internally.

I agree with Ralph. I have never seen much evidence about the internal structures of the funnels. Any attempt to recreate it would be almost completely speculative. One vessel which might provide some clues would be SS Nomadic. Regards Bob Read

I'm pretty sure Nomadic's present funnel is a re-creation. The original seems to have been removed when she was converted to a restaurant. The Queen Mary's original funnels were also replaced unfortunately.
But your suggestion is sound; maybe other surviving steamships can give us some insight into funnel construction.

Unfortunately, neither of the original Queen's funnels would be informative regarding the Olympic-class liners. While the outer funnels were elliptical in cross-section, the inner portions looked more like a subdivided box, or "egg crate," and were true extensions of the uptakes. Also, the outer funnels weren't built as a single assembly -- instead, they were individual segments that were stacked (pun intended!) one upon the other. The photo below shows the QM with No.1 funnel still missing the top ring; the normally hidden top of inner funnel is still visible here:

Thanks, I didn't realize that about the Queen Mary funnels. I believe the Normandie had the same 'egg crate' arrangement in her two working funnels.
Your photo, showing 'Liverpool' painted at the stern, brings to mind a bit of trivia I read recently. It seems the Queen Mary never actually visited her port of registry, which gives her something in common with Titanic.

Yes, Normandie had the "egg-crate" type of inner funnel as well. In fact, I've noticed this, and variations of this arrangement in other ships and, always, it sees to go hand-in-hand with the application of watertube boilers. The tops of upper inner funnels of the Ballin trio also appear to be divided fully to the top, based upon available aerial photos and others which allow a glance at the funnels from this vantage point. By way of contrast, it seems that all of the photos I've been able to find of large ships having many firetube boilers connected to a given funnel, it appears that the inner funnels were divided only as high as the casing tops, while the upper inner funnel was a simple undivided tube of the same cross-section as the outer "skin" which concealed it. It would seem to me that there must have been some advantage in draft to be gained in keeping the flues separated to the very top with watertube boilers, that didn't apply to the operation of Scotch boilers, whether they be coal- or oil-fired.
