Gerhardvienna got a reaction from Tadeusz43 in USS CAIRO by Gerhardvienna - RADIO - live steam
After all that more theoretical stuff it`s time for smoething real. Today I started with the 12-pounder carriage. This is a really small thing, just about 3,3 cm long without the wheels. The main part is soldered from 4 pieces of 0,5mm brass sheet, still some parts missing, but things go on.
Best regards, and many thanks for yll your kind likes!

High interesting stuff! I will take some time tomorrow to study all of that things and try to bring it to my Cairo model. Thank you for sharing!

Indeed it is an extra piece of work, to find missing datas for that ships. I`m awaiting all of your research results, so maybe there will be more to come into my model of the Cairo too. But as I`m making a floating model, there will not everything be made after the newest results, but I intend to make all the outside parts correct. Your model will be (and is!) a beautiful piece of artwork, I`m fascinated from it!

Attached is the Revision E(draft) of our Gateway Model Shipcrafters Research Outline which identifies issues with existing data being used to define the Civil War era City Class Ironclads.
We are following the results of this research as we scratchbuild our 1:24 scale model of the USS St. Louis for the Missouri Civil War Museum but wanted to start sharing it with with all interested model builders

Some more steps done for the small carriage, just the wheels, barrel and the frame for the ammo boxes missing.
Thank you for watching

Hi johnhoward
This version of the capstan seems to be too far away from the Cairo`s. It is driven by a single cylinder engine, while the suspected engine should have been a double cylinder engine, when I look at the shape of the machine base parts. The only thing I have to find out is where to place that engine. The gearing setup can be adapted for the capstan, no matter where the engine will take place, time will tell.................
Best regards

Very nice work Gerhard,
We'll be starting ours soon, but of course it will be twice the size at our scale and should be a little easier to make.
By the way I've attached another possible version of the capstan steam power system in case you don't like the PTO shaft idea. We originally preferred this idea before we determined it would be in the middle of the coal bin. It does look very similar to the Cairo gearing setup.

Gerhard,
Attached is a photo of our USS St. Louis ironclad taken a month ago. Unfortunately we found it impractical to manage or maintain the real time log on this forum but we have retained all the data and I am trying to retroactively bring the log up to date. We have 9 of our Gateway Model Shipcrafters participating part time on this project which has been in continuous construction since September 2014 and we expect to take at least another year to complete. As you have independently recognized for your USS Cairo, researching to verify or correct the enormous amount of conflicting or missing data for the City Class Ironclads is a full time job by itself.

Hi Gerald
This is really helpful! So I can make my choice for the boats, and maybe start with one of them! Thank you

Hi johnhoward
EVERY hint helps, Thank you!
By studying the sketch above, this could have been a 26ft long cutter. I found one pinnace at the NMM Greenwich collection, wich will be around 16 cm length in 1:50 measure. even the shape comes close to the drawings, but the boat is a bit younger, from 1878. But I expect that there were not so much changes in shape on such boats, so I will go with it. Just the one Launch is still what I wonder about length and shape. By searching for "Bristol Boats" I fell over the Atkin&Co Site, they show a good drawing for a 15ft 6in. boat, even similar to the Cairo drawings. http://www.atkinboatplans.com/Oar/BruceConklin.html
Best regards

I`m doing my best, therefore are so many requests I have to make. Still one more, what size did the ships boats have? Soewhere I read about 2 different types of boats, see the pic. I just dont know at the moment where I found this
Hi Mark
That`s what I`m afraid of, that a lot of things simply disappeared for some reason, and is lost now maybe forever.
Regards& thank you all for stumbling in

Beneath the studys about the second auxiliary engine and the 12 pounder I made another gun barrel ready for 3D printing. This time is was the Rifled Army 42 pounder, 3 required for the model.

Hi johnhoward
Found both books by googlesearch, interesting things to learn for me. As I have learned more in the past few days than in years before! So the doctor should be built in but turned 90deg. not as Gene Bodnar did show it in his Cairo model: http://www.modelshipbuilder.com/e107_plugins/forum/forum_viewtopic.php?5406.60
When there was no power assisted steering, the other auxiliary engine will have one reason only, to assist the capstan? If we (or you) can find out, where to locate this second auxiliary engine, I will make it too, just for the reason it was there!
Regards
Gerhard

Hi johnhoward
Thats what I found out by scaling the drawings to same measure. The so called auxiliary engine would have been far larger than the driving engime. I thought, that the auxiliary engine could have driven the capstan and MAYBE the steering, as it was done on different (german) river tugboats, while the Main Auxiliary Engine "the Doctor", was used for filling the water boiler. If that scond auxiliary engine was used for steering too, this could declare the giant size of it. But in the drawings I did not find any hint for that!
So there is a lot more to find out how they have built the ship, and how they managed to steer it! The fire room did probably not have enough space for an extra engine, so the place of it could have been "around" the Doctor, or at one side of the vessel in height of the capstan. The plansheet I`ve shown before shows the top view of the engine, there you can see a rod to port side of the engine, but unfortunatly not further parts of it. So we will have to speculate, how the parts we know did work together, and what parts are missing! To illustrate what i mean I`ve made a little sketch fron the auxiliary engine with the Doctor as a simple square set in.
Best Regards &Thank you for your worthful help!

Hi johnhoward
So I could go with the carriage from post #151 exept the lighter wheels. Measures are good to see in the markerhunters article https://markerhunter.wordpress.com/2011/01/17/dahlgren-12-pdr-small-bh/
Many thanks for your help!
And another request too..............
In the plans from Vicksburg I could see, that there were a Two Cylinder steam engine named " Auxiliary engine". Wher the he..... was this built in, location was shown as unknown, whe I followe the plans!
