    1/350 Tamiya Yamato Operation Ten Ichi Go with Pontos upgrade

    Hi boys and girls

    I haven't been able to do some modelling last year or so but the move to our new house is nearing. Still lots to be done but I'll have my proper hobby room so I'm eager to re-start some older builds of mine, like the 1/350 Tamiya Yamato new tool kit with upgrade set by Pontos from South Korea.

    I'll start posting some progress from the past in several updates to start light the fire so to speak ^^

    Here we go:

    First some history.
    The Yamato class of Battleships consisted out of three ships: Yamato, Musashi, and the into aircraft carrier converted Shinano. A fourth ship was under construction, but with progress of the war it became clear that Battleships were obsolete technology and the hull was scrapped.

    The Yamato class had the largest naval guns ever fitted to BB's: 18.1 inch or 46cms. The blast of the main guns when firing was so heavy and dangerous that the AA guns near the gun towers had to be stationed in armored turrets. Tests with the guns - where live stock was put on the decks - had as a result that many of the animals were heavily wounded or even killed by the blast.
    There's a very rare photo of Musashi firing her guns. It's clear that this was quite impressive.

    Yamato was a top secret project and the Japanese population never knew of the existance of these ships during the war (except for the crew of course, top naval hot shots, people working on the shipyards and some lucky few who saw them sail by). The Americans never knew the exact displacement of these BB's, nor the caliber (positive estimates were 16 inch in stead of the 18) until after the war.

    Yamato and Musashi were prestige projects and because of that, they were often stationed in safe harbours like on Truk for instance. Some people claim that Yamato never achieved much during battles but that's not entirely true.
    Recent investigations proved (US photo film was researched) that Yamato during the Battle of Samar ( a couple of sea battles were called 'The Battle of Leyte', the Battle of Samar was one of those) hit the escort BB USS White sands from a distance of 24 kilometres. One of the longest range hits ever. Six impact splashes around USS White Sands can be seen on photos. Yamato was the only Japanese BB in the area with a three gun per turret configuration, so this proves that these impact splashes could only be of Yamato.

    I'll be building Yamato as she was configured during her last voyage for Operation Ten Ichi Go (Heaven Number One). Japanese naval brass had decided that a fleet consisting out of Yamato, 8 destroyers and one cruiser had to sail for Okinawa to support Japanese troops. The ships received just enough fuel to get there. Once arrived to Okinawa they had to deal with the US fleet. If this didn't work out, the captains had to strand their ships on the beaches and use the ships as stationary artillery, while the sailors could fight as ground troops. (Both the captains and Vice Admiral Ito didn't agree with this plan and they tried to get as much fuel as possible).
    It was clearly a suicide mission.

    On the 6th of April 1945 the fleet sailed of but they were spotted fairly quick by two US submarines. These were too slow to keep up with the fleet though.
    April 7th Yamato and here accompagnying ships were discovered again, this time by plaines of a US flotilla. Originally the US Navy intended to send some BB's towards Yamato to intercept and fight her but after some discussion it was decided to send airplanes from a couple of aircraft carriers instead.

    Around 12.30 the first planes attacked Yamato. Initially Yamato's maing guns fired some Anti aircraft ammo towards the planes but it didn't do much damage.
    Three consecutive waves attacked Yamato with a lot of bomb and torpedo damage as a consequence as can be seen on this diagram and photo.

    Some hours later it became clear it would be too much for the mighty Battleship. 22 torpedoes had struck Yamato. Eventuelly the rudder became blocked and she started doing circles. She listed very heavily towards starboard and started to capsize. When Yamato rolled over the 18 inch ammunition hit the walls and ignited. A gigantic explosion followed.

    3000 souls were lost, including vice-admiral Ito.

    Next: the start of the build.

    The kit used for this build is the Tamiya 1/350 New Tool Yamato, and I used some extra goodies by Pontosmodel

    Tamiya gives you two options: you can build the ship as a waterline model or with a full hull. I went for the latter and in time I'll add a seascape and a crew :flushed:.

    The hull consists out of two parts: midship and stern as a whole and the bow part. Glue and nuts make for a sturdy fit. Although the kit isn't perfect and some gaps need to be filled and sanded down.

    The Yamato class had two rudders: a main one and an auxiliary rudder (Bismarck could have used that one :tongue-out3. The propellor shafts are metal ones, a nice feature.

    When the hull was assembled I gave her a primer coat of black Mr. Surfacer 1500 and after that had dried a basecoat of Tamiya Hull Red was sprayed on. In reality the red color of Yamato was much brighter than the standard IJN hull red but oh well, when she's fitted in a seascape not much will be seen of that.

    The upper side of the hull has a casted degaussing cable. I'll be using an aftermarket etch part so the moulded part was gently cut off.

    As can be seen on the photo the degaussing cable is already attached to the bow. It's quite some work but at that time I discovered Gator Grip glue and this glue gives you some time to fiddle a bit with the part. Excess glue can easily be removed with a bit of tap water.

      The upperdeck was attached next. Impressive piece of detail: the baerings of the gun turret are even moulded, though they won't be visible at all.

      The aft deck is a Pontos etch part which fits right on top of the Tamiya part. Details like rails for the smaller vessels and bollards are glued in place.

      The bow section received it's replacement parts as well. Very clever engineering. During the years one of the smaller parts was eternally lost to the carpet monster so I'll need to make a replacement.

        The aftermarket set had some nice turned barrels as well. Sadly, the exit holes were off set so I had to wait for replacements at the time. But I couldn't wait to assemble a main gun turret and dry fit one of the bad gun barrels.
        One of the AA guns was constructed to. Very small and many, many parts :tongue-out2:

        To give you a sense of scale: on the next photo I compared the AA gun next to a 1/35 Tiger road wheel and a tooth pick:

        The tamiya kit has also an error: each side of the hull has six ventilator holes. In reality on side had one ventilator less, so the gap was filled (Japanese believe symmetry brings bad luck, I think this might be a reason why one side has a fan less)

              This is wizardry of the next level. It will almost be a shame to see paintwork covering the jeweller-esk brass-work.

                          This is a fantastic blog. Luv the history lesson at the start. The build itself is epic. Some stunning work with the PE. I wish you all the best with this mammoth build

                            Ralph, thanks chap. I agree, lovely sets and their after sales service is great. I bought this set when it was new and with the flawed gun barrels I contacted them and they sent me proper drilled replacements together with some missing parts.

                            Steven, thanks, hopefully we don't need to wait for another 2-3 years :smiling5:

                            Jack, thanks mate. No wizardry though, just loads of patience and even more loads of swearing :tongue-out3:

                            Paul, thanks mate, hope I can do that indeed ^^

                            Hi Jim, well, the move isn't there just yet. First new windows need to be installed, together with new floors downstairs, a lot of painting and new ceiling in the living room as well. Hope we can manage all of that before end of April :flushed: Thanks for the compliments.

                            Peter, thanks. They sure do. It's quite cleverly engineered. Although some parts gave me some headaches as well. The main mast is a pain in the bum to assemble and so far I haven't managed to get it right.

                            Ken, thanks chap ^^

                            Chris, thanks for the enthousiasm :smiling:

                            Hi Steve, the move isn't complete just yet. Just nearing LOL. Photos will follow when properly installed. And thanks bud

                            Let's try another update, shall we?

                            Some more aft ship work was needed.
                            After doing some research on the internet (and by now I also have a great book about Yamato and Musashi by Janusz Skulski with loads of technical sketches as well as 3D work) it turned out that Tamiya didn't get everything right. First a photo for discussion purposes:

                            As you can notice the Tamiya kit has 9 larger support beams and 5 smaller ones. This isn't right.
                            The large Yamato model in the Yamato museum at Kure, Japan shows a different configuration:

                            7 large support beams and 5 smaller ones
                            Strangely enough pretty much each aftermarket company has taken over Tamiya's error. So I ommitted some of the excess ones in the Pontos set. Because the placement of the beams is somewhat different I had to file down some a bit. An hour of work or so and one side was finished.

                            After that, it was time to give Yamato it's teeth. Main gun turrets number 1, 2 and 3 are finished. The guns of the front two turrets just fired their 'San Shiki' model 13 or bee hive ammunition (AA ammo) on a group of incoming bandits.
                            Some guns dropped again to the loading position while some others just fired or are firing. Makes it a bit more interesting.
