The Ship Model Forum

most excellent !!!

similar in 1/350 I did on Koeing I built in 1999

I toned down the white with a light veil of hull gray, then overpainted the Paris green between the numbers with a microbrush. I like it now. The figures are a bit larger than before, but hey...





Fitting the remaining rear canopy supports, and the cable connecting them.

Some progress.

Installation of the C-turret deck railings, and the stanchion on the same deck. There are still many to be installed at the rear of the deck.

Drawing of what would be the winch used to turn the boat cranes. I don't have any photos of this equipment. I used the ship's plans to imagine it, schematize it in 3D and then print it out. I waited until the last moment, hoping to find a photo or a document.

I still have the 4 garbage chutes to draw and print.





Note that the bridge stanchion are mounted longitudinally on the Bretagne and Provence battleships, and laterally on the Lorraine (with the X at the top so as not to impede passage).

Pascal,

Have you ever tried searching for patent drawings for the winches or other equipment?

While working on my Oklahoma City CAD model I stumbled across the patent for one of the winches on the ship. It had very detailed drawings of the winch and its parts.

Then I started searching for other things and found patents for the entire guided missile launching system and the TALOS guided missile! Hundreds of detailed drawings!! It was the last place I expected to find such information.

The salt rime at the water line of the ship looks very realistic.

Thanks for the idea, Phil.

But I couldn't find anything about it. Not sure if it exists in 1910 for the Navy and if it is eventually digitized. Already, not all warship plans are digitized.

Drawing and printing the garbage chutes:

There are 4. I have good detail photos of the chute. They could be slowed down with canvas to avoid soiling the hull too much, later in the 1930s black stripes were painted on the hull to visually mask the soiling.

Are these general refuse or ash chutes?

Both probably.

During the 1924 refit, the ship converted some of its boilers to oil-fired, and during the 1930 refit, all boilers were replaced by oil-fired boilers.

After refit 1924-25, only the front ones exist.



On 1940, as you can see, this equipments still exists forward.

Searching the plan :

"Manche � d�tritus" : Garbage chute

David, from an English forum, pointed out to me that the large volume of ash was probably sent overboard by an ejector as documented on the Titanic:





Digging a little deeper into the bilge plan in the Battleship Bretagne's boiler room, we can probably see the ash ejectors in the fore and aft boiler rooms.

They are called "Escarbilleurs" in French, a name derived from escarbille:

"Fragment of incompletely burned wood or coal that escapes from a furnace."

Escarbilleurs:

"Grate under the firebox that collects the poorly burned particles (escarbils) and separates them from the ashes, in a boiler using solid fuel (usually coal).

Here, these devices are located on the starboard aft and port forward sides of the 2 boiler rooms. I think the term has been hijacked a bit.

There would be ash and slag. I gather the ejector works by the Venturi-principle, so it may not transport larger particles. These may need to lifted up in a different hoist. The ejector would need somewhere a pretty big ventilator.

Originally, there would have been probably ash-carts or -trolleys that move on rails around the boiler room or on an overhead tramway. There needs to be a hoist for those trolleys and more overhead rails to bring them to the chutes.

An ejector can be activated by water or compressed air, in this case seawater, which is most often used on ships.

It's still used on today's merchant ships in several places on board, and I've used it very often.

To dry out seawater ballast tanks, because it doesn't get de-primed like an ordinary volumetric pump.

And to create a vacuum in the freshwater generators on board, where the seawater boils at 60�c with the vacuum, allowing the 90�c engine cooling water to be used to heat the seawater and evaporate it to make freshwater.

If the venturi is wide, a lot of soil can pass through it.

Another type of ejector, on the side of the ship:





Hydraulic ejector for bulk material, recent, But the system hasn't really changed its design.

simple design to transport bulk materials
applicable for small quantities for short distances
with abrasion resistant linings
simple design for mixing bulk material with water
no moving part, less maintenance

Bottom ejector:

I'm still going around this battleship to install the railing, there are a few lengths to form and glue!

I've also installed the starboard gangway forward. I still have her lifting masts to draw and print. I'm going to replace the aft ones, which don't conform.

I've found a photo that shows me their shape.







I still have to install the stantions for the aft mast platform. These are higher. I'm hesitating between resin or piano wire. The fear, as they're high, is that they'll bend over time... Maybe a mix, with one base in resin and the rest in piano wire, would be a good idea.

I'm working again on the sailors who will board the "Bretagne".

I'd like to reproduce the beautiful scene in this photo, which I like very much, showing sailors on the deck at the port bow of the "Lorraine" in Brest harbour and workers from the Arsenal forging parts.

I would place it on the starboard side for the Bretagne, the side that will be displayed in its showcase.

I replaced the civilian workers with sailors.



I'm starting to get a nice crew, but I need a lot more different poses.











I'm also going to reproduce this one, the sailors with their lunch tin queuing up outside the galley door on the port side of the C turret.



This scene also shows the 340mm shells being loaded into the ammunition bay.

The shells were loaded by this removable mast at A and D turret level, through a hatch in the deck.

I made some officer today!

Well, it's a general's outfit, but it only shows sailors at 1/200 scale.

No shoes in this new character and his outfit, strangely, too bad, but it's not serious. I'll have to get them for myself.

Two more sailors on food duty, and I've still got one to do with a crate.

The scene of the forge is finished.



I'll move on to the soup queue.

What software are you using again for these figures?

There is a lack of commercial naval figures in intermediate scales, indeed. I will have to fashion mine from N-scale Preiser-figures.

I use Daz Studio, the software is free with free basic character (Genesis series), but addons are paid for outfits etc. ... The prices are minimal in the DAZ store, but it's a small investment.

Of course, it pays for itself very quickly if you have a resin printer, given the price of resin miniatures on the market.

What's more, the postures are perfectly suited to your project.

Relatively easy to use, even though it's free software, but a bit messy. You have to use it a little to learn. But it's still quite magical, I think.

I printed this prototype some time ago at 1:200.
