Model Yamato painting- 2 (finished, almost)

A few photos of painting the model Yamato. I used Tamiya paints. Spray cans for the large areas- and hand brushes for the small ones.

The entire hull was primed, then the water line masked.
Masking tape to define the waterline, then a quick, careful spray with dull red. Lovely colour. Not dull at all.

Then removed the masking tape and applied some more tape over the red. Painted the top half of the hull, and the other modules, “battleship grey”. Then glued the modules together.

The wooden decking is laser cut and the individual planks are laser marked. Incredibly thin… not measured but maybe 0.25mm. And have a paper backing which when removed exposes the adhesive. The pieces are extremely accurate for the model, fitting into their spaces and around winches, guns etc. NO trimming was required. My only issue was that some areas required extra adhesive. I used Tamiya Ultra Thin Glue, and it worked well. Great care was required in positioning the sheets.
And some hand painting of small details. The superstructure tower, funnel, 5″ guns, anti-aircraft cannons, and main aerial. The wooden decking was then applied. See how accurately it fitted around all of the deck machinery and guns…
A close up of the wooden decking detail. Very impressive! And not expensive. Cost about $AUD20 including postage.
The fore and aft flag posts are very fine, and inclined to catch in clothing and break. After repairing them at least 10 times, I reinforced them. Can you see the dressmaking pin? The cavity to the left of my finger is the lifting well for the aircraft, leading to the hangar.


The end result….

Superb shape! And this photo reveals that at least 95% of the ship volume is within the hull.
9 18″ guns in 3 barbettes. The wings on the barbettes are range finders. The decks around the guns were kept as clear as possible because the blast from the 18″ guns was huge. 20kg/cm^2
Yamato could carry up to 8 spotter planes. Launched by catapult, and picked up by the crane at the stern.

The model is complete, except for the flags and aerial cables. Took me a week to make and paint. I really enjoyed the build. And I really like the model. It was not an easy build, but the real credit goes to the people who designed and made the kit. It is truly impressive how well everything fitted together.

Now. Where to put it? And how to keep it dust free?

Yamato-Painting1; Restoring an old Westcott 6″ wrench.

The 1:350 Yamato model is made of plastic. Mostly Polystyrene, but also a small amount of ABS. Different glues required for each type of plastic. Both types will hold the parts in a minute or so, but several hours are required for rigid holding.

There are 17 different colours specified, which explains why the paints were so (unexpectedly) costly. Mostly IJN grey, and dull red, for the hull exterior, and wooden deck tan. I bought Tamiya spray cans for the dull red, IJN grey, and primer. The wooden deck tan was unavailable, so I bought some laser cut sheets of impossibly thin wood, already in the correct colour, and made for this particular model. Pictures later.

So I sprayed the primer coat.

The question was whether to make the entire model, then paint; or paint the individual parts on the sprue frames before assembly ; or something in between.

I thought that painting the entire model would be simplest, but some small parts and areas would be inaccessible, and the result would be messy.

Painting every component on the sprues would leave a bare cut area on every part which would need to be touched up later, so that did not appeal. Plus it would be very time consuming.

So I decided to make the ship in modules, and paint each module separately.

The painting modules….. the hull is just 2 colours, IJN grey, and dull red below the water line. Some masking will be required. The other modules will be painted individually. As seen, 99% of the gluing has been finished.
So today I applied the primer coat. The paint is touch dry in about 10-15″. I started with the underside of the hull, then turned it over, on the box as support, and painted the decks. The box was exactly the correct size to support the deck without damaging the tiny attachments.
Then the smaller modules. The alligator clip attached to a chopstick was a handy way of rotating the workpieces, and minimising painting my hand.
Still some small parts to be attached, but they will be different colours which is my reason for not attaching them before this. This is one of the 18″ gun barbettes.

Tomorrow I hope to start applying the final colours.

Painting is really NOT my thing. So to finish the day I spent some time restoring an old small Westcott adjusting wrench which had been given to me by a friend.

It has an interesting, appealing shape. Sadly abused, bending and breaking the jaws and bending the rather nicely curved handle. So my first step was to disassemble the parts. The moveable jaw had seized so I punched it out.
I tried to cold bend the fixed jaw but it would not move. So I used a hand hack saw to open up the crack, then bent the jaw back towards a right angle. 3 successive cuts and bends were required to get it back to 90ยบ.
Then V’d the cut, almost to the box inner section. Then arc weld filled the V. It wont be as strong as the original, but will be OK for light applications.

Finally some time was spent grinding and sanding the weld flat, and filing the parts make them slide easily. It was still a bit sticky, so some “Gumption” was used to smooth the action. The handle was cold bent back into a nicely curved shape. I might get around to blackening the wrench by heating it and quenching in dirty sump oil.

Model Yamato

So far, glueing up the model has been interesting and a lot of fun. Look at the progress after 2 days….

The guns and superstructure are just sitting there. The components will be separated for painting.

The tools which I have found useful are lined up.

Alligator clip on a chop stick, rubber bands, Extra Thin Tamiya Glue for polystyrene plastic, flat non serrated small pliers, needle nose small pliers, safety razor blade, sharp side cutters which I have modified so the cutters are thin and very pointy, steel ruler used as a scraper, small fine file, fine sand paper, fine tweezers (actually from my microsurgery kit of 30-40 years ago), coarse strong tweezers, and utility knife. And of course an A2 cutting board, and Tamiya Instruction book which I have found to be accurate and very helpful.

The Extra Thin Tamiya Glue is very good. It sets in a couple of minutes so parts can be finger held in position. It is so thin that it tracks into small cracks by capillary action. And it is transparent. Time will tell how paint adheres to the glue.

The Tamiya parts are also very impressive. Beautiful smooth finish, minimal flashing which can be scraped off with a finger nail. And the parts fit together very accurately, for the most part. Rarely I had to use the razor blade to make parts fit together, and that was usually because I had missed a bit of the sprue when separating the parts from the sprue.

This was one of the first areas to be glued.
Large joins, like this foredeck to hull, were glued progressively, holding each bit with a rubber band. The deck has a bend, and I could not hold it in place with only my hands, but the rubber bands worked pretty well.

It was quite exciting to see the hull coming together.

Many of the parts are extremely small, and too light to feel. The fine tweezers are very handy for these. So far I have lost only one part after dropping it.

I am close to painting the components. I will use Tamiya spray cans, brush applied paints for tiny parts and fine lines, and possibly an air brush. I have been watching YouTube videos to pick up hints on the painting process. It was surprising to me just how many YT videos exist on the subject of painting model Yamatos.

Then the major components are glued together.

Then the smaller guns and other surface equipment will be glued on to the painted surfaces.

P.S. Another 1/2 day gluing up these tiny planes. One more to go.

These really tested my eyes and hand control. Cotton bud for scale.
This cheap Banggood LCD microscope was very useful. Only trouble was that it magnifies my shakes. (Mustool G1200)odel
