come on, another little video

The Barrels
The barrels were created using a 3D printer, followed by two coats of black and yellow paint. They were then meticulously sanded with very fine sandpaper to give them a worn effect. Finally, they were coated with two coats of colorless matte varnish.
The Shark's Jaw
The shark's jaw located on the facade of the upper cockpit was also created using the printer.
The Mast
The mast was made using a 14 mm diameter pine dowel to lower the center of gravity and lighten the model. The rungs are made of brass and the lookout is made of copper, which is easier to bend. The shrouds are made of 0.8 mm diameter polypropylene ropes, dyed steel. The 12V micro bulbs used by our colleagues on the train helped me with the mast lights and signal lights.

For the sound animation, the model is equipped with a "JQ6500-28P" MP3 and WAV player module with a 12V stereo amplifier, two 10-watt, 8-ohm speakers, and a 12V/4.2V power supply. This equipment allows me to play five different sounds or music. There are a few iconic lines, and especially the film's soundtrack.
The patina
Very fine triple-0 steel wool is immersed in water. After a few weeks, it oxidizes and becomes rust powder. Finally, these particles are mixed with colorless matte varnish. The final step to reveal the signs of aging is to apply this mixture to the new paint and wipe it off immediately with a soft cloth.

The Staging
In order to recreate some of the film's key scenes, it was essential that a monstrous creature from the depths pursue the model. To bring this carcharodon carcharias to life, I chose a 41 cm long rubber figurine that can be easily found on an online retailer.
To submerge it, a copper tube was installed along the length of the bilge, extending a few centimeters through the hull at the stern. A second fiberglass tube is screwed to the first at a slight angle. Inside, a 2 mm thick rope is attached to a 13 kg servo winch and passes along the conduit, at the exit of which the shark is attached. When the winch is wound or unwound using one of the radio control potentiometers, the shark dives or rises to the surface.

To design the bait buckets at the stern of the ship, medicine tubes from my medicine cabinet were cut and painted. They were then filled with resin to represent the meat. I placed small pieces of lures found at any fishing tackle store. The hemoglobin effect is reproduced using red paint. The splashes were created by projecting droplets of paint using an old toothbrush and one of my index fingers.
As with all my constructions, I couldn't do without incorporating some radio-controlled animations. Thus, the tillers and gear levers on the upper and lower sections are functional thanks to mini servos coupled in parallel with the speed controller and the rudder.
The 12V micro-bulbs also equip the deck spotlight and the cabin interior. Flexible ducts were positioned on each side of the hull so that the cable route was executed as neatly as possible.

The table top wasn't a problem, however, as for the legs, there was only one photographic archive, and unfortunately it was very blurry. So I had to copy what I saw. The result is quite satisfactory.
By researching fighting chairs for big game fishing and being the size of my character, the copy wasn't too complicated. All the wood, aluminum, and vinyl fabric parts of this chair were glued with Araldite.
The ladder is made of 4 mm steel. To make it, I first had to trace it on a piece of wood, then use a router to mill the lines to the dimensions of my steel bar, i.e., 2.5 mm deep, so that the uprights and rungs would be square and wouldn't move during brazing.

Cabin and Deck Layout
There were challenges, particularly in terms of almost non-existent documentation. Not wanting to be approximate, but rather to be as precise and faithful as possible to the objects used in the film, I created my own database by capturing dozens of images of the film. This was the only way to get as close as possible to reality.
Thus, each of the objects reproduced is a strict copy of those found in the film, including the brands that correspond to those existing at the time, whether for fire extinguishers, scuba tanks, the first aid kit, beer cans, tin cans, safety instructions, the International Code of Maritime Signals, radars and sonars, etc.
The furniture was made from 3 mm poplar plywood. Small 6 mm brass hinges were essential for the cupboard door openings. A piece of foam resized to fit the bench and wrapped in burgundy vinyl fabric allowed me to create the cushions. A few small round-headed nails covered in this fabric form the buttons.

The deck is made of 3 mm plywood and is fully removable to allow access to the electrical components for possible maintenance. To represent the caulking between the wooden slats, lines were simply etched with a scriber. Once varnished in dark oak, the illusion is perfect.
The Cabin and Cockpit
To create the cabin, the exterior and interior walls were cut from 1 mm 3-ply plywood. The panels were then glued together. Wooden spacers were inserted into these partitions to accommodate the various wiring used for the lighting and window installation.
The port and starboard sides of the upper cockpit were made of 5 mm plywood, as was the instrument panel. 1 mm plywood was used for the exterior and interior walls of the facade. The scribe method using my scriber was also used for the vertical battens.

The keel was cut from 18mm plywood scraps, in four pieces. One of the segmented sections was used to hold the stern tube. The frames were made from 10mm plywood and perforated to facilitate the routing of electrical cables. The hull has a hard chine, which made assembly quick and easy.
Once the hull was finished, it was simply fibered and resin-coated with G4. Then, a coat of filler and sanding was applied to remove any imperfections, followed by the application of a few successive coats of paint.
To mount the exhaust system, a copper tube was inserted into a beech log that had been previously drilled through its center. The collars to support the exhaust were made of aluminum. The assembly was painted and aged.
