The Ship Model Forum

Not much today, I did a bit of scale 1 auto mechanics for a change.
Drawing of the gratings�near the funnel and the engine room skylight which is not finished.
There are still two tanks to be made in that corner, one fresh water tank (kitchen taps, cabin) and one sea water tank (for flushing the toilets I suppose), then the galley skylight.

Any idea why there was a wooden grating at the base of the stack?

The stack and general marine architecture remind me a bit of the Hong Kong "Star Ferries", though they are open and optimized for a more tropical climate. Though diesel powered, not steam.

Don�t know Tom..

A very interesting colour photo I have just discovered showing Ingenieur Minard ex Nomadic dating from 1966 with the Queen Elizabeth in the background.

You can see that the boats are not covered by a canvas (awning) in 1966 but by sheet metal plates? The colour is also noticeable, perhaps chamois, like the chimney of the White Star.

I already had my doubts about the canvas awning after finding photos of the boats stored in Cherbourg before the rescue of the N�2. This replacement came later in the life of the boat, because in the first years of operation it was canvas.



A new, larger, rectangular freshwater tank is also clearly visible. Another ferry is moored next to it but it is not the Traffic that was scrapped by the Germans during the 39-45 war.





The engine room skylight.



Thanks to the photos I found recently I was able to reconstruct and modify it in its version that I think is close to the original.

I represent it open, because it must have been open when the boiler was under pressure to evacuate the heat from the engine room which was not well ventilated.

I am following this with really great interest--and your desire to get things as right as possible
is a strong drive.( and mine by proxy! )

ref the grating at funnel base ;
by being elevated and thereby allowing the deck to dry, could it be to prevent the build up of algae and slippery surface on the steel deck in that area
the ' shape and layout of that grating would lead me tho reckon it is so as to give secure footing for the guys coming down off the funnel ladder,

and give secure traction to feet when when trying to rotate the cowl vents...


...as you are still at the 3D stage with the open hatches,
That excellent photo of the man ( scale ) and the hatches is a really great find !

may I suggest first ( this might be rather more work--so maybe not worth it to tighten the radius of the hatch corners?

and ( hopefully easier ) to halve the thickness of the (safety cross-bars on the hatch ?
On your render--compared to the photo--they look too chunky to my eyes

Looking at the chap, the photo suggests these to 7/8" - 1" in real life approx ( 22-25 mm )

on a finished printed actual model--the cross bars on the engine room hatches will stand out against the
dark background of the ' hole' and white ( especially 2 layesr of paint! ) and that might make them too dominant
and look over-scale in my view

ref the boat covers-- that great observation
never occurred to me!!

I think you are correct in suggesting its metal - probably very thin plate
maybe on a hook-in hinge type on the central spine
( might possibly also be a tye pf plywood-maybe not

-though it looks too flat and even for wood--which would try cup and hollow over time .

whatever

GREAT works on a an often overlooked type of vessel !

Best wishes

Tks Jim! Best wishes too!

Indeed Jim, but the skylight is very small at 1/200, the cross bars are 0.25 mm in diameter, the extreme limit of resistance to tearing for the resin during printing, not for the printer.

The drawing of the 3D parts could be much finer, but I have to take into account the printing scale for each part and be very careful not to go below the tolerable printing limits. It's frustrating for the designer, but that's the way it is.

I'm certainly not teaching you anything Jim, it's also like that to inject it and even worse, the more you reduce the size of the vessel the more the parts are simplified, sometimes coarse. There's the simple example of ship railing that become huge on some models at very small scales, better not to put them sometimes, even in PE which has its limits too.

It's too late to change the radius of the panels, I found this picture late after I almost finished the drawing, difficult to go back sometimes with Fusion 360 without disrupting everything ...

Some pictures of the upgraded capstan, added the steam engine. Second picture show the galley skylight and the tiny sea water and fresh water tanks.

My (limited) experience with the printing process is that sometimes the printer will fill in nearby items, such as foot or hand rails next to a bulkhead, so the spacing must be exaggerated. For other examples I printed some nice 1:192 stokes litters, which came out much finer than the rendering, the actual diameter of the lattice came out considerably smaller than the design (about .30 mm designed) but printed well and were strong enough because of the structural strength of the lattice and short distance between points.

Pascal is very experienced with these design engineering problems. Myself learning through trial and error. There is a definite buffer between what you see on the screen and what emerges from the printer. Perhaps as the technology evolves this buffer will shrink. It is possible to print fine railings, but they have the structural integrity of overcooked spaghetti. I am hove to in the doldrums currently waiting for a couple of items to resume printing.

Regards to all! Tom

Very happy with the impressions of these elements (in 48 minutes), I reduced to 25 s the exposure time of the first 3 without incident, it still sticks a little too much, 20 s should be good. (Mono X 3D printer)

I left the tanks on their supports except one set, to avoid breaking the very fragile pipes.

The engine skylight is very good, the diameter of the bars to prevent sailors or passengers from falling into the engine room do not shock me. I would see when painting.

For the gratings, I'm going to redo some, the square holes of 0.15 do not cross, I'm going to redo them in 0.3mm of side. I had taken example on the coffee table of living room which in gratings of 32,8 mm, that is to say 0,164 mm in the 1/200... I suspected it a little, but I had to try. �

I had spotted this small ventilation duct on the first photo, the other photo pointed me to its shape, a shape resembling the Olympic class but much smaller.

You can also see that the air sleeves were not as high but with a larger diameter than when they were remanufactured during the restoration in Belfast.

On picture two, we see the new position of the mast which has been moved compared to 1912, we also see the covered walkway and probably a radio antenna.











Titanic ventilation duct in the same style:

In fact it is this model, I found it on the book of Bruce Beveridge's Titanic, either oval (photo) or round (plan).





It must look like this, I made it a bit big, I'll scale it down:





I don't know if it's the only one on this bridge, but I have a doubt. I think there are two of oval type in front of the fireplace, it looks like it anyway.





I started to draw the compass, there are still a lot of details to add.

This drawing is coming to an end.

I used these two images as decals.

https://www.canstockphoto.fr/rose-vent- ... 19880.html

It was fun to draw this compass, I had a good and beautiful period model in pictures.

I'm going to tackle with pleasure the wheel steering, and the spare lanterns of the navigation lights these next two days.�

Tonight to motivate myself on this long and difficult double project, I made a little diorama of my own. We could call this painting:

"SS Nomadic waiting for the RMS Titanic, coming from Southampton, on Cherbourg roadstead on April 10, 1912 at sunset."

Drawing of the steering wheel:

I was inspired by this picture, the same maker as the Titanic probably:







The one in Belfast which is not the original;







The unfolding of the drawing. It's quite simple to do, 3 hours and 30 minutes of work. The texture of the wood has to be adjusted.























It is better this way, to be refined with the compass.

Finished steering wheel. Tomorrow it will be the turn of the navigation lights lanterns.

All this detail just blows my mind. Fantastic stuff.

Thank you Martin!

Port and starboard navigation lights are completed.

Magnificent work and research all around.

Thanks Dan!

The drawing of this ship is almost finished, there are still some details to be created, navigation light of the foremast, small mast and aft navigation lights, some pulleys for the lifeboats, and the tracing of the upper deck planking, still a small day to complete these details after a few hundred hours of drawing since the beginning of November 2020, that is 2 months of design working on it every day.

There are a few flaws, but I'll deal with them. This is my second ship entirely designed in 3D and printed in resin. The next one will probably be much better, the experience gained will avoid me some mistakes.

Today I put the handrails, and the batayolles very particular to this ship with 5 bars, impossible to find in the trade. So I'm going to print them at the finest, 0.3 mm, it's going to be fragile but conform.

Pascal,

Very nice work!

How many passengers did the ship carry? What was the capacity of the lifeboats?

Looking at the two lifeboats I can't help thinking that the Titanic didn't carry nearly enough lifeboats for the number of passengers aboard.

I realize the Nomadic operated close to shore, but only two boats seems to have been inadequate.

Phil

Thank Phil.

SS Nomadic capacity was 1000 passengers. Only two small lifeboats 19,6 feet and life jackets..
SS Traffic, same capacity, but smaller (Third class passengers and freight)

10 avril 1912:
Boarding of passengers on board the Titanic:

��On board the ferry "Traffic", 15 passengers disembarked from the Titanic as well as some freight. The 102 third-class passengers waiting to board the world's largest passenger ship boarded first for the journey on board the Titanic.
The other White Star Line ferry, the Nomadic, also takes 179 passengers on board: 151 first-class passengers, including some of the greatest fortunes of the century, and 28 second-class passengers, all bound for America. French luxury goods such as champagne, wines and cheeses are also on board.��

there is sooo much fabulous wok in this project.

I am very very impressed!
