Battleship Bretagne - France - 3D realisation - 1:200 scale


Recommended Posts

Printing of a 340 mm prototype turret, there is not much to review, it is rather good. The assembly is well done respecting the tolerances of the resin 0.3 mm. 

 

The printing is very fine thanks to the Photon Ultra, especially the padding and riveting.

 

I printed with 30 micron layers, but I'll test again at 20 microns.

 

I chipped the sealing skirt a bit when I was removing the paint, it's very thin there. No problem, it's a test. Otherwise it runs well with the system.

 

I've primed the hull, and sanding and repairing the little dings is in progress.

 

About the colors:

 

From "Les Cuirassés de 23500 tonnes" Bretagne, Lorraine, Provence:

 

5. Paintings and particular marks :

 

51. Paintings :

 

The hull up to the waterline is painted green (Schweinfurth green), the deadworks and superstructures are bluish-gray, a classic color since its adoption in February 1908. Only the strake on top of the chimneys is black.

From 1915 onwards, i.e. during the test period, the steel of the 340 turrets and their guns was stripped and treated with a "grease plug" to prevent corrosion. These "grease plugs" contained a mixture of grease and lampblack, which gave the main artillery turrets the shiny black color that can be seen in photos from that period.

Towards the end of the war (1918), the upper half of the AR. mast was painted black to avoid the soiling caused by smoke.

In compliance with the Ministerial Circular of November 30, 1920, the waterline is painted black over a height of one meter (0.50 m on either side of the waterline 10).

The boats are painted bluish gray with white interior. The vertical parts of the deckhouses of the launches are kept "clear" or varnished if they are made of wood, otherwise they are painted in the color of the boat. The roofs are painted in grey for the steamers, in white for the launches.

52. Particular marks :

Since 1912, the particular marks of battleships and cruisers consist of white rings painted around one of the chimneys. These rings allow, within a squadron, to identify the division to which a ship belongs and its rank in that division. The code used has already been explained during the presentation of the Courbet type battleships.

Between 1916, the year of their entry into service, and their first redesign, the three Bretagne frequently changed their particular markings, so the study of the latter is the subject of a table in the appendix, common to all battleships of 23,500 tons."

If anyone has existing paint references for the bluish gray, Schweinfurth green, linoleum red ochre (Here can be the Tamiya XF-59 ("Linoleum Deck Brown")?

For the 380 and 140 gun turrets, I'm thinking of using two colors, a dark charcoal gray for the turret itself and a semi gloss black for the guns. 

 

We can see on the 1915 photos that the color of the turrets varied according to whether a recent layer of grease plugs had been applied, from shiny black to medium dark gray. It must not have held up well in the sun, sea spray and rain.

The printing work is progressing, and also the precise adjustments of the 3 large elements of deck 2 before they are glued together, that takes a little time.  

 

Only the front part 1 and 2 of deck 2 are glued together, I just printed the rear part 3, which still needs some adjustments. But it looks very good.

 

This deck 2 will not be glued to the main deck of the ship right away. There is a further precision to be respected to avoid breakage which is always possible.

Tks.

 

Printing the front of deck 3. It fits perfectly.

 

Deck 2 is fitted and the 3 elements are glued together.

 

The toilet scuttles have printed well, you can see the small holes.

 

The front chimney is being printed, result tomorrow morning.

 

Then I will continue to climb to the bridge. 

 

I'm missing a tap on a scuttle, I'm good to reprint.   🙄

Printing of the bridge deck ( Deck 5 ), charts room, bridge "blockhouse". Nothing is glued and not really cleaned of course.

 

I decided to print the railings, it's not bad at all.

 

Deck 4 of the superstructures with its railings is being printed.

 

The other railings will be printed separately, too complex in terms of media to print in one block.

 

The different elements and the way they are divided to be printed easily. It works well.

Wonderful stuff as ever. 

 

Can I ask a simple question, what diameter (actual not scale) are those railings?  I'm currently not doing below 0.3mm dia on rods as otherwise they are too weak.  Those railings look smaller than that to me.  I'm also using a Photon Mono 4k btw

 

Cheers

Tks Ian! 😉

 

Printing again of the stack but in two pieces, it's even better, for the de-grappling and the painting.

 

Printing also a lot of small parts, and the protective railings, but which are also used to store life jackets and not hammocks as said above.

 

The spiral staircases are very well done, very fragile. The more classic ladders too are nice.

Reprint of the bridge with the railings, but in two parts.

I have 4 of them. 

2 Anycubic Mono X 4K
1 Anycubic Photon Ultra
1 Phrozen Sonic mini 4K

 

I mainly use the first 3.

Hello Pascal,

I have the Phrozen Sonic mini 4K, which experiences you have made with this?

Do you have any tips using it?

Regards Andreas

I use it very little, I'm not a fan of the brand. The prints are not always good, it's not consistent. I use it to print transparent resin mainly. The finish of the machine is also a bit cheap.


I will not buy another printer from this brand.

 

I'm waiting for the next generation of Anycubic printers for a change, I can't wait to see what will be offered after the 8K.

Towards the end of the war (1918), the shaft of the rear mast. is painted black in its upper half to avoid soiling due to fumes.

Extract from the book by Laurent Roblin and Luc Féron. "La Royale à la Belle Epoque".

 

719-ZR0s-JRLL.jpg

 

In 1995, Laurent Roblin, chief curator of the Musée de la Batellerie in Conflans-Sainte-Honorine, discovered a large metal box at the bottom of one of the museum's storage rooms. Inside, fourteen boxes of glass plates? This collection, which had been sleeping in a storeroom since 1967, turns out to be of inestimable value. 

What are we looking at? 

 

223 images of exceptional quality and totally unpublished, based on the theme of the Royale, the French Navy, from 1895 to 1914.

 

Translate:

"The boundary between the dead and the live works is materialized by a white band about 25 cm above the waterline.

As far as the color of the living works is concerned, the campaign specifications all specify, when the matter is mentioned, that during the passages in the basin, the hull was repainted with "Schwein-furth green". We also owe Jean Guiglini the formula for the composition of this painting, and we give it here for the benefit of model builders who would like to get a closer look at reality. (Extract from the magazine LA NATURE ler semestre 1930 p. 47).

 

- Mercury soap 15%
- Rosin 20%
- Turpentine 20%
- Lead soap 15%
- Linseed oil 20%
- Copper acetoarsenate 15%


This last material, toxic for marine organisms, and having a very bright aquamarine green color, gives this paint its tint and its anti-shellfish and algae characteristics (nowadays, it looks like an "antifouling" paint)
But the problem is not so simple! Indeed, the black and white photographs of the building taken during this period all show, under the white net of the waterline, a dark area that cannot be the result of a green tint. Furthermore, the paintings, watercolors and colored postcards generally show a red area under the white line in question. Finally, the estimates for the work done on various buildings at that time, and on the Bouvet in particular, mention, in addition to the Schweinfurth" green, the use of lead minium in large quantities.

The explanation seems clear to us and is, for example, visible in the photo of the Carnot at the basin. While the minium was used as a protective layer against rust, a layer of "Schweinfurth green" was applied afterwards to protect the hull as much as possible against organic dirt. When floating, the main problem is corrosion - it is the oxygen in the air that attacks the iron; this is probably the reason why an area of about one meter, painted with minium, was kept at the top of the living works, just under the white border.

Lovely work Pascal.  I know you are determined to print the whole thing, but I must admit I would have been tempted to make the masts from brass tube with printed features.  Given my clumsy hand I'd have broken them already :doh:

 

Merry Christmas

Awkward, awkward... You're a little too hard on yourself, Steve! 😂

 

I gave it a shot, it worked. I'm reprinting a set of two mats with easier to remove holders. 🤔   I may have to make copies of this battleship for others. So it's better to have this problem solved before, in the heat of the moment, than later.

Some pictures of the progress of the painting.

 

I used Humbrol 144 matt for the hull and superstructure. 

 

Humbrol 96 matt for the steel decks.

 

Revell 37 matt for the linoleum decks.

 

Shading with N°9 matt Revell anthracite. Turret also with N°9, chimney top with Revell matt black n°8. The straps are a little lighter with a mixture of Humbrol 9 and H 144 grey.

 

For the hull, first layers with Humbrol 37 matte green, then SM364 Revell green.

 

I still have to work on the hull which is too light for my taste to get as close as possible to the "Vert de Paris", I have to add some shading around the sheet metal plates before reinforcing the SM364 green to darken it slightly. But for now the effect is the right one, I don't want a uniform hull colour.

 

All this in anticipation of the ageing of the whole. 

 

Nothing is glued yet.

The problem was that the Humbrol 37 green doesn't cover anything, it's water, first time I used it, I used up 1 and a half pots for the coat.  

 

The SM364 green covers well, so that'll do it, but then my shading took a hit, so I'm going to redo it, then 364 again, then a coat of clear matt after aging to immortalize it.

 

The red surface corrosion protection strip is painted with Humbrol matt 60 which I mixed a bit.

 

I printed out work supports for the hull to avoid damaging the paint, they are aimed at the place of the supports of the final display. Practical.
