  1. Not too much progress today, some housework took me a lot of time this week and it's not over... Drawing of the aft strait or stream anchor, this evening. There is still the system that allows the anchor to be tipped overboard to be made, called " Mouilleur ". The stream anchor keeps the ship in a defined axis in a river or a narrow place with or without current. Generally, the two front anchors are dropped in crow's feet, then the strait anchor is dropped backwards, releasing chain at the front, and then backwards to obtain a balanced position with enough links in the water at the front and at the back so that it does not slip.
  2. Rob, you sew as well as my wife ( That's a compliment! ) Nice job!
  3. Drawing of the Anti Rolling keels. Not easy in general. But I have my method that works pretty well now.
  4. Thanks Rob, It will be necessary to transform this drawing in the real world and that it remains as beautiful. Thanks to HD photos of the Bretagne found on the US site: https://www.history.navy.mil/content/history/nhhc/search.html?q=BRETAGNE French battleship&ts=false I redrew the windlass/cabestan, the mooring bollards, different from the front ones, the air vents, and the sighting radomes for the torpedoes. A system to calibrate the guns can be seen, probably, on two pictures. This one is from elsewhere. We can see a typical skylight, very interesting. You can see on the deck the rails for the mobile projectors.
  5. I did quite a bit of documentary research today on the stern of the ship, the layout of the deck maneuvers, capstan, ventilation ducts and skylights. I have very few pictures of the stern, or the few I have are of the Lorraine or Provence, arranged differently. So I didn't make much progress today. But I learned a lot of things. There is still a lot missing.
  6. Tks all! Drawing of the rear main deck with camber, and the first deck. The casemates of the main deck, plus some details. I have the flagstaff to tilt at the stern.
  7. For the moment I'm focused on the 1915 version in terms of drawing. I will draw the 1940 version next, as I now have the necessary plans. It's a long job. After a few days of vacations, I'm back to playing the 3D mouse. A nice stay on the Ile de Ré, France. Lighthouse of the Whales, September 22nd, the weather was nice! Personal photo. Click to enlarge Today I worked on the rear of the ship and its 140 mm casemates.
  8. This towing cable stopper allowed the battleship to tow another ship damaged or out of propulsion during a fight or other events. The tension on the cable could be managed by this device.
  9. I'm not a fan of this kind of transformation, but I have to admit that you did a damn good job, Steve!
  10. This evocation of a 1907 Moissenet stopper from the Battleship Liberty is finished. I'll see if I have time to animate it, otherwise my friend Bernard will do it. The strut works on compression here. It is on the back of the stopper. The deck is reinforced at this point. -------------------------------------------------------------------------- There were also Moissenet claws that allowed to stoppering off a cable.
  11. It's coming to an end, I'll be able to continue the ship. There are still a few things to rectify and draw.on the brake. A new and different rendering, the Fusion360 app on IPad, this app only allows visualization and measurements.
  12. Small progress: The cable brake still needs to be designed. We can see the spare corners and counter corners on the intended platform.
  13. Tks Andreas, very interesting. You can see how it works here: The two shoes move apart thanks to the screw at the bottom (one step to the left and one to the right), the lower yellow friction pad which is placed on top of it rubs more or less on the cable, braking it with the help of the upper wedge. This screw is driven by the bevel gear return, the chain and the large flywheel. The upper wedge with the two handles is also adjustable with the other handwheel, it can be slid into the device, so that the wear due to friction can be compensated. Spare parts are available for the top corner and its opposite wedge. I don't know what the material is, maybe a Ferodo type material. "Ferodo is a British automotive supplier based in Chapel-en-le-Frith in the non-metropolitan district of High Peak, Derbyshire. The group specialises in the manufacture of braking products for both consumer and competition use1. History In 1897, Ferodo began manufacturing brakes for carts. In 1902, Ferodo introduces the first brake lining: an innovative and revolutionary step in the world of braking In 1922, Ferodo became the first company to supply original linings for production cars, equipping the Austin 7. Ferodo became the first company to stop using asbestos in brake linings by 1980" There's still a lot of stuff missing, the design is far from finished.
  14. I didn't make much progress today, I wasn't at home. Too sad, no direct access to this slide show. https://imagesdefense.gouv.fr/fr/le-sto ... enet.html# "This device is used when towing a large tonnage vessel and allows the operation to be made safer by braking or stopping the tow-roap , so that the personnel can control the speed at which the tow-roap is pulled. After these generalities, the slide show moves on to the description of the stopper: its general diagram and its frame for attachment to the deck. The next part is devoted to the operation of the stopper, the hawser spinning is explained by diagrams. The last part is devoted to the use of the stopper, diagrams and commented photographs explain how to prepare and carry out a tow with the stopper. Presented by the Navy's military schools. Prepared by the Manoeuvre School."
  15. Thanks Will, I don't know.. The drawing of the stopper continued today a bit. The top gears and screws are in right-hand pitch on both sides, I'll rectify that later.
  16. New rudder design following the plan, it gave me a bit of trouble, quite complicated shapes: All the layers of the cutting plan laid on their respective plan. The rudder is 7 meter long. On the right is the old rudder, much simpler. Thanks to Chris' plan, I was able to start drawing the famous Moissenet stopper. To my knowledge, there is no photo of this device. So we will discover little by little what it looks like in "virtuality" thanks to the magic of 3D, then in reality, once printed. This morning I also studied the functioning of this stopper to better read the plan (which is not so simple) and to understand the drawing in good conditions. I'll talk about how it works with a little animation at the end of the drawing. Battleship Liberté:
  17. Tks all. Fusion360. No, I'm a self-taught amateur, I started learning two and a half years ago during the Cov confinement.
  18. I'm going to redraw the rudder as I have the exact plan, I had drawn a head one which is not very accurate except for the profile which is. Propellers in place:
  19. Love this carrier, CV-1 too. I will do it one day, when I have the time.. Can't wait to see what happens next!
  20. Design of the propellers. Their diameter is 3 meters, designed for speed. The propeller pitch is 2m54. Although the Bretagne is not very powerful compared to what will be done later, 43000 hp, 21.5 knots. A French destroyer of the 50's is powered by 63000 hp, max speed 32 knots. Luckily, I have quite complete plans for once (thanks Chris). Among other things, the plan of the blades (called wing on the plan), the sections at different heights, it's really easier to realize with this information. You can also see on the plan, how the central nut is braked after tightening and how its flats are protected by a sleeve which comes to fit from above, closing the hub cone. The 3 screws that can be seen around are used to fix it. Nice work! The small screw on the cone of the nut is probably used to fill it with hot liquid tallow that will freeze in the cone later on, thus protecting the thread from corrosion and water ingress. It's just an hypothesis on my part, but it seems to me that it reads "filling with tallow" on the plan, technically, it makes sense. I could use this propeller for other ships by transforming it into 3 or 4 blades depending on the model. To make a left or right hand propeller, one click is enough.
  21. @ Stuart : With these new generation 3D programs, it is much easier to approach this discipline. I'm completely closed to the programs I've tried. After that it's a bit of self-training with the help of tutorials on Youtube, which are extremely well done. There is no secret. You have to practice. Sometimes you have to go through moments of great solitude at the beginning. Of course you have to like drawing. The 4 propeller shaft lines are almost complete.
