  1. Back to the SS Delphine project for 7 days: Drawing of the main deck aft ventilators, capstan, bar service, and the spare wheel helm. Remaining is the Brooklynn-made telephone to communicate with the engine and bridge, and the compass.
  2. Some accessories added on the foredeck on Sunday. The third windlass has no clutch, the lowering protections to the windlass chain wells for the sea packs, sheaves for maneuvering the anchor fouled by the arm (make a turn of chain around a leg of the anchor), I have others to draw double for the front cables of the anti-torpedo nets, the front fairleads (The model varies between the plan and the photos), the flagpole that very specific to leave free the fairlead of towing, it supports the removable anchor light.
  3. Not much to present, yesterday was a very complicated and time consuming day for digging the hull at the front because of the integrated hawse pipe in the hull. The front part is well advanced. I can now drill the portholes. Drawing of the small deck accessories. Tomorrow, I'll take over the SS Delphine project, alternately, for one week. Drawing of the anchor chains just for the drawing, but I'm also thinking of printing some. The shape of the forestay mesh is rather oval, I drew them a bit big, to be reduced. Drilling of the starboard portholes, port is a little different. The door you see under the waterline is the door of the starboard front torpedo tube. There are 4 of them. 2 forward and 2 aft.
  4. This is quite normal, it can be that good, until the hole in the film FEP. It doesn't affect the performance at all. The only problematic thing is if you need a super flat face on your part. A small bump on the wire can create a small defect on that surface. Do not forget to put the protective film on the LCD screen. Even if there are some bubbles, it is not very important. The screens are expensive.
  5. I don't know the date of this picture and which sistership. I think the guns were replaced/modernized as they were refitted or the plan is not good. I drew these guns according to a plan dated 1915. Since then I have received other plans with a different shape at the muzzle of the gun, more modern. I will probably modify the 3D drawing, it's quite simple. Base of my drawing: Dated 1915: Bretagne Dated 1916: Sistership Provence
  6. The foredeck is slowly being furnished, 350 mm mooring bitts, roller fairleads, lazarette hatch that can be covered by a canvas shelter. I reduced the size of the turret hatch, I had missed the plan, I'll see if I make an open one, it could be nice. There are two hatches one on top of the other, a very thin one that covers the armored one. This last one is equipped with a lever arm to open it because of its weight. The first one can only be closed from the outside, it protects the armored one from rain and sea spray, I think. This picture had me on the trail. You can see the thickness of the turret roof armor ( in 3 sheets ), probably 60 mm. Compared to the 210 of the sides. This roof is removable, it allows to replace the guns. Rear turret, guns dismantled, we can see the fixing screws of the roof which was temporarily put back in place. (Lorraine)
  7. This is a "Normal" phenomenon, because during the diffusion of UVs through the pixels of the LCD screen, the UVs diffuse a little at the periphery in the resin. This makes the part a bit oversized. For a simple part no problem. But for a part that has to be assembled to another one, it's a problem, on both parts Drawing of the capstan and windlass PS and SB, the third one is a bit different. The steering wheel is used for the brake. The 3 identical squares in the case on top of the windlass are used to engage it with a crank. It allows to anchor "on the brake", windlass engine out of gear. Here on the plan the position of the crank is quite dangerous, we can suppose that it was extended in reality to avoid that the hands touch the anchor chain. Another era. Anchoring to the brake: Traditionally the number of shackles ( One link: 15 fathoms or 27.50 m) put in the water is announced to the bridge by ringing the bell (for sounding shackles), which is at the forecastle usually, 4 shackles, 4 rings of the bell etc. On this bulk carrier in the video, it is by hand signals. Now there are UHF walkie-talkies, but given the noise when anchoring the bell is still the most effective, even 200 meters back at the bridge we hear it clearly. Then the anchor black ball is hoisted indicating to the other ships that we are at anchor. 2 white lights at 360° also indicate it at night, at the front and at the back.
  8. Hello Ian. I will start again on Monday Delphine, then it will be every other week, alternating with Bretagne.
  9. Drawing of the ladder, displacement of the turret hatch towards the back, it is not placed as on the plan, photos attest it. Note that the roof of the turret is not really armored (see plan), only the sides and those of the barbette are (around 240 mm). Battleship Lorraine:
  10. There are still a few details to be added on the turrets, railings, 47 mm guns, ladders to access the turret hatch, plus other small things. I was able to draw some details today. In particular the sealing system at the barbette level, these little turnbuckles that you can see holding the braie in place. I also put the two articulated grips that block the turret at sea in rotation at the sea station. It took me a while to figure out what these arms were for, but a rare photo where they are in place confirmed my hypothesis. They are not on the class plans. The hatches to the right and left of the cannons, are for the two sight lines. The small hatch between the guns is for lateral aiming.
  11. There is still some detailing to be done, but also the internal system of the turret in order to be able to glue the two guns easily with their "braie" (I don't know the term in English). They will not be adjustable in elevation. But it's possible by modifying the design and printing guns with a higher elevation, and also the floor supporting the gun mount. For the moment I've drawn the turret rangefinder, refining the bottom of the turret in shape. The fixing system to the barbette is drawn, the turret will be able to turn. The gun braies are in 1915 version for the moment. They have a different shape later, probably during a redesign when the maximum elevation of the guns was increased for more range. The clearances are increased on the parts that fit, this is due to the fact that the resin 3D printers make the parts a little larger than the design, about 0.3 mm for the Anycubic LCD printers, or on a cylinder 0.6 mm, so it is necessary to take this into account when designing. For the Photon Ultra which does not use a screen, it is much less. I will print a prototype with this one to validate the design of these parts. We can see that the guns of the B turret graze the rangefinder of the A turret in the 0° position. The -5° could only be reached in the lateral position of the turret, in my humble opinion. Later version of gun braies, probably after 1919 (The elevation of the main artillery was increased from 12° to 18°).
  12. A friend of mine gave me the plans of the turrets. Even with these plans, I must say that it was not easy to draw it, the design is more complex than it seems. From the cylindrical turrets of the pre-dreadnought to these ones, there is a world. The design office had fun! Some pictures of the turrets sketches, we are still far from the final printable version...
  13. Many thanks, Chewbacca, Stuart! The anchor is finished. It's always better to have a plan of course. Perpective errors, parallax etc.. So many parameters on a photo that can distort a 3D drawing. It should look a bit like this: Here it is, the anchors in place. Modifications of the hawsepipes on the forecastle with the addition of this part which is difficult to model and to integrate. Example on the Jean-Bart ( 1910 : A few railing added. But it will be 2 rail IJN PE that will be put in place.
  14. I waste time with the plans which are heterogeneous, it's hell, when you superimpose them, there is no 2 identical ones... Probably plans of studies which did not succeed for some. We can see that some shapes, especially at the level of the side barrels, have been modified in order to simplify the manufacturing process, probably or for other technical reasons. I had a lot of fun with the 140/55 guns, I wanted to make them swivel in elevation, but it's impossible with the hard "braies". Well, I drew the mechanism anyway. I put the breakers in front of the front side barrels, there are some on the second group too. I have good pictures that give the angle of the breakers. I started to file the parts in two folders 1915 and 1940 to segregate the two versions. You will just have to click normally to switch from one version to the other in the drawing. These are of course not the original gun mounts. These cannons could be removed from the mountings to put them under cover and perhaps for maintenance inside the bridge. Being permanently exposed to sea water, they must have suffered from corrosion. Removing a cannon was not an easy task despite the overhead travelling crane, especially at sea with rolling, pitching and seas. Hence perhaps the decision to remove the 4 front 140 mm guns from 1922. Working this morning on the "alcoves" of the 140 guns. It's full of little subtleties, I have a few to add on the turrets. For a change, I'll draw the anchors. I took some pictures at the "Pointe de Pen-Hir" near the port of Camaret, Bretagne, France, on the "anchor path" last March, it was not insignificant. http://baladesbretagne.canalblog.com/archives/2016/10/10/34422182.html http://4sardines.canalblog.com/archives/2011/04/28/21004171.html "...The first anchors came from the Toulon arsenal recovered from the warships that took part in the battle of Mers El Kébir (Algeria) on July 3, 1940: Cuirassé Bretagne, Cruisers Dunkerque, Strasbourg, Courbet..." One of the anchors of the Bretagne is there, at least the same model, and another one of the Courbet, among others (they are different). I was careful to take a picture of the front and side. My wife gives the scale ( 1m65 ). It's a perfect match. Anchor of the Battleship Courbet:
