Amazing work and great attention to detail.

Pascal,
Thanks for posting these latest pictures. I had been scratching my head trying to figure how that thing works! Especially the "U" shaped part that moves on the two threaded screws controlled by the red hand wheel. Now I see it was used to push the wedge back to loosen the grip on the cable. Something would be needed to loosen the grip because friction with the cable would pull the wedge very tight into the device.
Very nice drawings! There a lot of little bits and pieces like this on ships that end up consuming a great deal of modeling time. But for me that is just part of the fun!
Phil

According to what I was told, the "U" shaped part is used to adjust the friction more finely, it is on the side of the towed boat.
The large handwheel is used to get as close as possible to the cable, a coarse adjustment.

Somehow this design is very complicated with expensive to manufacture gears, such as diagonal ones ...

Sure..
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 R�, France.

Lighthouse of the Whales, September 22nd, the weather was nice!

Today I worked on the rear of the ship and its 140 mm casemates.

I think it was to hide the name of the ship at the time of the photos ( War 14-18 ?).
I don't see these plates anywhere else than on these two photos taken in Toulon probably.
I will not take them into account.
After these plates disappeared, the name was written with letters in relief painted in black.

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.

The speed with which you work in 3D never ceases to amaze me ...

Tks!
Thanks to HD photos of the Bretagne found on the US site:
https://www.history.navy.mil/content/hi ... p&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.

Drawing of the Anti Rolling keels.
Not easy in general. But I have my method that works pretty well now.

Pascal,
I'm in awe of this project - You've outdone (AGAIN!) your previous 1st class work.

Interesting "A" shaped design on the bilge keels, I can see where these would be very strong! As to the "hat" vents on the deck, is it possible these could be adjusted and closed from below by sliding up and down on the rods forming the legs? Always fascinating seeing how thins evolved in the industrial analogue era.

That's an unsual way of stowing the arm of the anchor, presumably to give extra security at this somewhat exposed position.
I don't want to criticise your excellent 3D-modelling job, but shouldn the arms be tapering to a sort of bulge in the middle, with a flange the rest against the eye in the anchor, being secured on the other side with a pin ?

Indeed, the drawing is not finish yet.

I continue on the stern with the drawing of the fairleads, always a little complicated to draw those.
The one on the side is used for the refloating according to the plan.
Addition of small details.
I found this very nice picture of the front that I did not have. It is very very interesting. I was missing the exact shape of the protection of the tube of the chain-lockers, I have it, I will be able to modify.
You can see the 47mm gun on the turret too.
