Thanks Joe, you welcome to the adventure :thumbs_up_1: It’s really nice to work on this beauty.

Drawing of the promenade deck supports on the forecastle. Laying of sheets on the underside of the hull.

I have started the superstructures, especially the places on the deck. This system of embedding is not bad, it's the third time I use it, it gives very clean connections between the deck and the superstructure.

I leave a 0.3mm gap between the two, because of the resin which can increase the size of the parts a bit, but this might be adjusted with a prototype of the superstructure.

So, taking note of the bow-thruster, you will model her as she is today, not as she looked originally?

Yes, I made the decision to do the current version. I lack the photo documentation to build it as it was in the 1920s.

There is this old and beautiful model which could have helped me, but it has errors, the author had to face the lack of documents too.

The book published on this ship would have helped me, but it is unobtainable and above all unaffordable.

After a few days of sunny holidays I am back to the virtual drawing board.

You can see how it was built and restored

Yes, photographs of construction or restoration are always useful to understand the structures.

Yes indeed, very important.

I've finished this forward block of the main deck. I can start another one, the forecastle.

Image

Image

Image

Small advance on the front. To be completed.

A few pictures of the underside of the forecastle and other places not or hardly photographed because less "glamorous", despite my daily research.

I'll have to trust the plans.

What are the underwater "holes" forward for? The design of the hull lines is interesting and typical of the era. Is the extension of the bow profile underwater (1) a function of possible ramming (2) a proto forerunner to a bulbous bow, which with the counter stern would extend the hull speed thru advancing the wave making forward and much like classic sailing yachts extending the effective waterline length aft at speed?

Cheers: Tom

The holes are the refrigeration sea water outlets and bilge, for the different devices. We often forget to represent them on the models, as well as the sea chest.

On this shipyard plan, they are very precisely represented.

Image

For the bow of the Delphine, indeed, although it was 1920, it is nowadays very fashionable.

The Bouvet ( France ):

Apparently Zumwalt isn't having a lot of crew topside on the forecastle! The USN "Standard Battleships" had a very similar stem to Delphine, it was the cruisers that broke this mold with more clipper like bows, which was followed by the fast Battleships. Counter sterns were abandoned by warships, the cruisers (USN) mostly evolve into transom sterns whereas the fast Battleships did not. Vanguard (RN) was an exception.

Great that you are doing another existing ship where a lot of information is available!

Cheers: Tom

Tks Tom! :thumbs_up_1:

Started the forecastle deck to be able to place some elements present on the main deck and the promenade deck, ladder, windlasses, hawks.

Somehow, this double rail around the forecastle is a somewhat unusual arrangement. Was this the original design or introduced later to make it e.g. drier?

The digital model comes on very nicely - and fast!

Thanks Wefalck.

The double bulwark did not exist when the ship was new.

This ship was built in a yard in the Great Lakes in the USA.

We can think that it was made to sail mainly on the lakes and not on the high seas.

Because of the shape of its bow, it is not very well defended against swell and big waves.

So in the beginning there was no second bulwark, there was a simple classic railing.

Image

Image

Image

Image

Canvas in place:
Image

Image

It seems that some ten years later, a second bulwark was installed probably during the second world war. I did not succeed in dating this modification, can during its transformation into a warship.
It allows to protect from wind and sea spray, the forecastle flush deck and the promenade deck probably. It was more robust than the canvas usually placed on the railing.

The SS Delphine renamed Dauntless ( PG-61) during wartime:

http://www.navsource.org/archives/12/09061.htm

Patrol Gunboat:

The second Dauntless was designed by H.J. Gielow and built in 1921 and built as the steel-hulled yacht Delphine at a cost of $2,000,000 by the Great Lakes Engine Works, Ecorse, Michigan

Launched 2 April 1921
Burned and sank in the Hudson River, New York in 1926
After four months on the bottom, was raised and rebuilt at cost of $750,000
Struck a rock in Lake Huron in 1940 off Manitoulin Island, Ontario, Canada, but suffered only minor damage.

Acquired by the Navy 21 January 1942
Commissioned USS Dauntless (PG-61), 11 May 1942
Decommissioned 11 May 1946
Struck from the Naval Register 5 June 1946
Transferred to the Maritime Commission for disposal 10 June 1946
Returned to her prewar owner, Anna Dodge Dillman of Grosse Pointe, MI and renamed Delphine
Acquired in 1950 by Horace E. Dodge of Grosse Pointe
Acquired in 1966 by Anna Thomson Dodge of Grosse Pointe
Donated to The People to People Health Foundation in 1967
Sold in 1968 to the Lundeburg Seamanship School of Piney Point, MD and renamed Dauntless

Sold in 1986 to Travel Dynamics of New York City
Sold in 1989 to Sea Sun Cruises, a French - Singapore Co.
Sold in 1997 to a European businessman and towed to Bruges, Belgium for restoration, which lasted from February 1998 to July 2003

Renamed Delphine, she currently operates out of Monaco.

The bulwark is transformed and is in one piece in 1942.

Extensively modified.

The Dauntless after war:

Today:

Image

-----------------------------------

I can't wait to print the first hull sections.

An HD image of the underside of the ship, my Imac took all night to create it. Just for fun, because all this will be inaccessible to the eyes. And it is also on the 1 scale model.

Some elements are missing, like the windlass drive shafts in the middle of the gangway and some sponges... The steam engine of the windlasses is below this deck.

It will be in place soon.

Click twice to enlarge.

I didn't do much today, I drew the windlass well where the drive shafts of the wildcats and gipsy go.

On the picture you can see the steam engine that drives the two shafts, under the main deck.

Drawn a little handrails and the railing of the stairs.

I started the windlass which is very special. It is inspired by the capstan-type windlasses of the warships of the time.

I only have one and a half photos to make it and a bit of a diagram. But it should be enough, you'll have to make do with it. I've had no luck with additional photos of the windlass so far.

Here is the sketch:

Image

Image

Image

Image

Image

Image

Image

Still a few things to review and add to get it finalized, but it should look something like this.

My guess is that the two handles are for releasing the port and starboard locker clench in case of hooked anchors on the bottom, or a problem with the windlass.

Item 13.

I think the handwheels are working band-brakes to control the chain, when it is running out.

Normally, there would be a threaded spindle with handwheel on the same axis, while here the handwheel sits perpendicular to the plane of the band-brake. There must be some sort of lever mechanisms inside the frame under the handwheel.

Indeed I drew it, it's a rather classic L of corner recall.

I started to draw the telescopic crane before. No plan of course, but some pictures taken from far away and the pictures above.

I don't have the brand of the crane, and I couldn't find it on the internet after having looked at hundreds of pictures of this type.

The arm is almost done, I have some modifications to do and then I'll move on to the crane body and the cylinders.

Image

Image

Image


Image

Image

......It's almost done, I need to get the arm up a bit.

Yesterday; Test printing of prototype parts of the forecastle with the brand new Photon Ultra 3D printer.

It's very good, despite the fact that I printed the crane horizontally, which is not the best for the printer and the part. But I wanted to do a quick test ( 50 mn ).

Another final print is in progress that will take more than 4 hours, but vertical for the crane. I have applied design changes on the next batch, the anchor chain turnbuckles.

Image

Image

Image


Image

Today: I am still "furnishing" the forecastle.

Front and rear capstans, no shots, partial or distant photos.

I managed to buy the SS Delphine book (1000 copies) from a private individual with a stroke of luck and at a reasonable price. It is a very rare book for sale and very expensive, the last price I saw on a book selling site was 200 euros...

There are 400 photos inside ( 328 pages ), I hope I will find my happiness. It comes from Belgium.

https://en.maremagnum.com/rare-books/ss ... /143384802

Image

The capstans:

Image

Image



Image

Image

Image

The new batch printed differently.  The holes printed well at the end of the anchor chain turnbuckles. It's the camera that doesn't follow anymore.

I know, I keep forgetting to do this myself, but could you put a coin into the pictures for size comparison ?

So, what's the diameter of the turnbuckles ?
