IJN Yamato by Wblakeny - DeAgostini - 1/250

[cog]

Your hull is starting to look nice and spiffy, Chris

[Old Collingwood]

Now that is looking impressive.

 

OC.

[WBlakeny]

Start of sanding

 

First i must make the rounding at her bottom plate.

To do so, i have to mark until were the rounding has to come on the bottom plate.

 

 

Then I cut off the corners carefully

 

.

 

Afterwards using I use an electrical sander.

 

 

The result :

 

 

[WBlakeny]

It's a this point in my build that I received my new copy of the new Yamato book by Janusz Skulski. 
I already was using the old version.

 

 

Much too my surprise, i noticed that the stern was completely altered versus the old version.

 

 

It's described in the book, that the stern was build in the fashion like the old Japanese battle ships.
Unfortunately, the book does not tell on what it was based to alter the stern so dramatically.

 

 

It's here that my build log is now to date.
So now I've made some photocopies at work which i enlarged to the scale 1/250. 
I also copied the body plan.

 

 

When i put my Yamato on the plan, it corresponds. Even at the stern, so that means that the deck at the stern is still correct.

 

 

But it's the lines beneath that have completely changed.

 

 

Now i don't know what to do, should i stick to the old plan, or do I alter the stern?

Decisions, decisions, decisions....
 

[CDW]

I know what I would do, but that doesn't mean it's the only correct answer. I would stick with the girl I brung to the dance. 

[popeye the sailor]

I sense a second hull coming...........  

 

this one looks too good to try and alter  

[WBlakeny]

I gave it much thought but i'm gonna take the plunge and change the stern.  

 

A bit further in the book of Janusz Skulski there are drawings of the rudder. It's also changed since the older version of his book and says it's based on the original Japanese drawings.

And since that shape of rudder was never going to be possible with the old stern on my ship, i decided to go for it. I hope it'll work out in the end, we'll see.

 

I've taken the dimensions of the plans which i had enlarged. There are 2 different dimensions for the stern.

 

 

First I've had to prepare a piece of pine to the correct dimensions.

 

 

With the scroll saw i obtained the needed profiles to form the stern.

 

 

Using a red marker i colored the wood which had to go, so i have an indication as where is still have to remove wood. 

 

 

A lot of wood dust was the result.

 

 

Unfortunately my first attempt was a failure, i had lost the curve at deck level. I had to redo all the steps.

 

 

My second attempt was spot on!

 

[cog]

You are a brave man ... Looks very, very promising!!!

[popeye the sailor]

just checking how that new 'tookus' is coming along.......

[cog]

It seems he is sitting on it Dennis

[WBlakeny]

Hello guys, i'm just back from a holiday. Not much time spend on my Yamato.

 

Just spend some quality time with the admiral and the kids 

 

I hope to be able to continue work on her this week.

[cog]

Good to have you back Chris,hope you enjoyed your holiday with wife and children. Now get to it!!! Make some dust, party time is over  

[WBlakeny]

Aye aye, sir 

[WBlakeny]

Wow, this is amazing, thank you for the links!

[WBlakeny]

Time to replace the stern on the model.

 

Carefully, using a small saw, i removed the old stern. 

 

After cleaning it all up and sanding it smooth, i glued the new stern in its place.

 

 

If you look at the sides, it shows clearly where the planking of the hull must be changed.

 

 

 

[yvesvidal]

I would not alter the planking too much. This will reduce the stiffness and integrity of the hull.

I would try to use some epoxy paste (or other things) to fill up the shape between the hull and the revised stern.

It may not be exact but with a lot of sanding, you may approach a good compromise.

Very brave!!!

 

When I look at your new stern part, I would have expected it to go round (bulbous) quicker. It stays hollow fairly long. My plastic kit starts round right away from the flat rear most part, which is inaccurate. You need not take a look at Greg's (RGL) Yamato, they have changed it to a rounded stern, which is, as we know now, incorrect. In the 2nd edition of AOTS it seems to me it goes quite fast to straight and flow into round. I presume you will need to get the putty out Chris, and do some sculpting

[popeye the sailor]

looking at it,  you might think that cutting it off 1 more bulkhead longer,  might have made the transition easier to blend in the contour.   but then you'd have to make another stern part to match it.  I'm sure you have a plan  

[WBlakeny]

I had already removed the planking and filed off a bit of the bulkheads so that the planking runs smooth till the new stern.

Then redid the planking till the new stern.

 

 

Afterwards sanded it all smooth.

 

 

And final result so far :

 

 

I'm happy with the result. I'm glad i took the risk of changing the stern. Who'll say what is the right stern, but now i'm following the new AOTS book and i'll stick to that.

 

 

 

[cog]

That's a smooth flow to the stern. Nicely done Chris

[popeye the sailor]

excellent repair!

[WBlakeny]

Thank you all.

I'm now in the process of sanding, sanding... and sanding.

 

Pictures will follow soon.

[cog]

I hope there is some hull left. You've been sanding for quite a while ... How's life? Missing your updates, Crhis ...

[WBlakeny]

Yes. There's still some hull left 😀

 

I'm sorry, i've changed from job and have not much time left for my ships. The shipyard is temporarely closed, unfortunatly, but i'm hoping it'll get better soon.

 

I'm missing the building alot though.

 

 

 

[cog]

I know the sentiment. I'm trying to squeeze some build time into my work schedule, but I have to refrain from the more elaborate things. I am working with a Belgium customer ... coincidence ...

 

Take care Chris

[popeye the sailor]

not hitting the like button........sorry to hear of your dilemma.  hopefully you'll get things sorted out and can continue.   your doing a super job there   

[Glenn-UK]

Good work so far. I have the kit on order so hope to start work on my build shortly.

 

Have you watched John's YouTube Yamato build videos?

[WBlakeny]

Hey Glenn, no i didn't watch those youtube videos.

Thank you for pointing me to them.
