Post Scriptum
===========

Gentlemen,

Today, I proudly present you the finished Yamato Rigging Guide.
In 34 different rigging procedures and 344 pictures, I exposed you the origin, trajectory and destination of Cables and Cords, Insulators and Lanterns, Brackets and Lug Rings in all the different areas on Yamato’s Rigging Manual.

In all these chapters, the location of qty = 146 Brown Ball Insulators and qty = 39 White Bar Insulators have been unveiled with corresponding text and pictures.
Let me tell you : it was quite a challenge during all those years but I did it with a lot of pleasure.

The articles : Terminology.

I am the first person to admit that these rigging steps can not be read like a novel.
Explaining how cables run from point A to point B, and all the unforeseen problems that show-up during that process is a challenge. It takes a special kind of language to explain problems to people and to simplify the description in a comprehensible way. To do so, you need to use technical terms and expressions.
That’s the main reason why all the rigging steps are written this way.
And repeating some words and terms countless times to avoid misunderstandings is a big part of the job.
So, yes, these articles are not meant to be read like a novel.

The Indicator Colours (arrows/ stripes/lines/circles/ tags).

You all noticed I did use a lot of different colours for these Indicators. Why so many different colours ?
Very simple : because of all the pictures I used in the Yamato Rigging Guide, there are not 2 alike when we talk about clarity or exposure. It’s possible that in a same picture, 1 single object needs different colours of indicators. And then I forget to talk about the back-ground colour which can differ a lot in the same picture. Changing background colours are a nightmare when you want to clarify an object in a picture ! So that’s the reason for so many different indicator colours: for clarity and contrast.
A little side-notice : as far it was possible, I tried to use Yellow Colour for Port side rigging and Blue or Light-Blue Colour for starboard side rigging. Did not always worked out like I wanted but sometimes it did. Good Colour codes make it much easier to understand pictures.

2024 : A brand new destination for the Yamato Rigging Guide.

When in Jan 2024, I restarted making articles for the Yamato Rigging Guide, some clever & forward thinking people of this site proposed me to publish my articles in the Tips and Tricks Section of the Ship Model Forum.
The reason for this proposal was to avoid that all Yamato rigging steps would be buried in the numerous articles of the 160 + pages “ calling all Yamato fans” section.
Consequently, all the rigging steps moved to the Tipps and Tricks section of the Ship Model Forum. If you go to that location you can easily find the Yamato Rigging Guide.


And the following address brings you to the first page of it !

And what about the original 2017 articles?
Creating new articles, from jan 2024 on, had a positive consequence : I was able to use more advanced computer techniques than I did in 2017. Nothing more than a time-related advantage.
But when I compared the 2024 publications with the 2017 articles, I saw an immense quality gap. A gap that needed to be filled.
So I decided to revise every article I published in 2017 and if necessary to adapt text and pictures accordingly.
Since end april 2024, all the 2017 articles were revised & corrected.
The visual indicators, or more precisely : the complete lack of them, is the reason why many new pictures were added, but this time with comprehensible arrows, circles , lines and tags.
A lot of text in the articles disappeared where I judged it to be obsolete and when it was not contributing to the rigging subject. I’m afraid that in 2017, I sometimes took the discussion too far away from the rigging subject.
The result today is that the 2017 articles are conform to the 2024 standards, shorter and showing more accurate pictures with comprehensible indicators, arrows and tags than before.
I consider this as a progress.

Any questions or remarks ?
I repeat myself from my first article on 04 march 2017 when I say that I’m not an expert. Not even close.
So it is possible that somebody, (an expert for instance) might discover errors or mistakes in my articles. I take that into account, already since 2017.
If such happens, may I ask you to send me a message via Ship Model Forum so we can solve the problem and make sure that the Yamato Fans receive correct data ?
Needless to tell you that every serious matter will lead to a correction of the relevant articles by myself.

Thanks
=====

For all the people that gave me positive comments for my rigging articles : Thank you.
I highly appreciated your posts & private messages during the making of the Yamato Rigging Guide.

I also want to thank Baseballbrat and Dan K. for their good advice and interventions when my knowledge and my aging eagle-eye came too short.
Thanks Jim! Thanks Dan K! You helped me very well…

When the publication button was jammed and the “next -to -be-published” articles were stuck in the pipeline, Dan K and Jim Baumann helped me several times out of my problems.
Thanks Dan ! & Thanks Jim for repairing the pipeline…

And I may not forget to mention Rob Wood. Everybody that followed the different rigging steps in Yamato’s Rigging Guide has certainly looked at some of Robs pictures without knowing it.
Thanks Rob, for allowing me to use your pictures. Today you can see they all served the right cause…

At last, I want to thank the guy- or lady that invented the snipshot technology. :smallsmile: You can not imagine what an ease that ment for me when I was preparing detail pictures for my articles.
Have a beer on me, snipshot guy- or Lady, wherever you may be !!

I hope sincerely that you all enjoyed the Yamato Rigging Guide.

It’s time for me to weigh the anchor.
And there is only one more thing left to say :

Gentlemen,
Have a nice day.

Thanks again Katana for this extensive look at the rigging of Yamato. Not only the rigging but the ship details. Like you've said from the start, no other exists on the internet but yours. We all here appreciate the dedication and the time it took to formulate a guide that's easy to follow along with backed up HD photos. Well done sir!

TIA

Jim

CHAPTER 06. STERN
Step 06.00. Rigging MC 1&4 above Stern up to the Ensign Staff

Gentlemen,
Today we will talk about the rigging of MC1&4 above the Stern, all to way up to Yamato’s Ensign Staff.

Before we take a look, it is useful to know that in all different pictures, the names, numbers and colour codes (when present) always refer to the same items. Much easier to understand this rigging chapter :
Blue arrows: MC1 trajectory up to Black arrow Nr 11.
yellow arrows: MC4 trajectory up to Black arrowNr 11.
Blue- or yellow ovals : Brown Ball Insulators.
Black arrow: Joint nr 11 where MC1&4 are merged into 1 single cable “L”.
Red arrow: Stern Crane tip with 2 separate rigging stations : the Upper Lug Ring and Lower Aft Lug Ring.
White arrow: Ensign Staff Lug Ring Nr 13 where Cable “M” is attached with a loop.

Pic 001: This is a schematic overview of the Stern Rigging area. It shows the trajectory of MC1&4 that run from the red-striped rigging area line to the Crane-tip.
Joint Nr 11 = where MC1&4 are brought together and form a new Cable “L”.
Cable “L” is attached with a bottlescrew to the Upper Lug Ring on Crane -tip Nr 12. In the aft-lower Lug Ring on the crane tip, Cable “M" emerges from another bottlescrew and runs towards the Lug Ring on the Esign Staff.
Pic 002: As a little reminder, this picture shows the rigging area of the Aft -Ship but most off all, at its left side , the red-striped line shows the end limit where the Stern rigging area starts.
Pic 003: this is a general Upper view where you can see the complete Stern Rigging Area.
Pic 004: Aft-Side view with all the items of the Stern rigging area.
Pic 005: Side view with all the rigging details in perspective.In this picture you get a good idea where the Stern rigging starts , left of the yellow striped line.
Pic 006: View of the Aft Stern area. Please note that in this picture all the Brown Ball Insulators are visible.
Pic 007: Detail view of the Ensign Staff. Prominent in this picture: Lug Ring Nr 13 to which cable “M” is attached with a simple loop.
Pic 008: Second detail view of Lug Ring Nr 13, but this time with the 2 last Brown Ball Insulators on cable “M”.
Pic 009: Aft view of the Stern rigging area with all its protagonists.
Pic 010: Detail of Crane tip Nr 12, Joint Nr 11 and Cables “M” and “L”.
Yellow arrow: Bottlescrew in Upper Lug Ring on Crane tip where cable “L” ends.
Blue arrow : Bottlescrew in Lower Aft Lug Ring on Crane tip where cable “M” starts.

Rigging procedure.
Let’s start and please use all pictures as a reference.
One should forget, but actually we only keep following the trajectory of the double Main Cables Nr 1 & 4 that transformed back into single cables in port & starboard joints Nr 10 of the Aft-Ship rigging (previous Main Chapter).
In many pictures, the red/ yellow striped line shows the border between the Aft-Ship and the Stern rigging area. Main cables MC1&4 come from beyond that line and go towards the Crane-tip on the Stern.
In Joint Nr 11, MC1&4 are merged into 1 new single cable : Cable “L”. Cable “L” contains 2 Brown Ball Insulators and it ends with a bottlescrew in the Upper Lug Ring of Crane-tip Nr 12.
In the other station of Crane tip Nr 12, the Lower Aft Lug Ring, Cable “M” emerges, also with a bottlescrew and goes down towards the Ensign Staff. On Cable “M”, 2 Brown Ball Insulators are installed near the Crane-tip and another 2 near the Ensign Staff.

The special lay-out of Crane tip Nr 12 : See Pic 010.
A. The Upper Lug Ring:
From the moment MC1&4 left the Side Mast tips, and travelled the entire trajectory up to the Stern Crane-tip, not one single rigging device was used to put tension on these cables.
That’s why in the Upper Lug Ring of the Crane-tip, a bottlescrew (Pic 010, yellow arrow) is installed on Cable “L”.
Remember: Cable “L” is the joint of the 2 Main Cables Nr1&4, so any tension applied on Cable “L” by a bottlescrew will be transferred on MC1&4 all the way to the port & starboard Side Mast Lugs.
What a considerable distance between the Crane-tip and the Side Mast tips, don’t you think ?

B. The Lower Aft Lug Ring:
This device is located on the aft side and a little bit lower than the Crane-tip. In this Lug Ring, another big bottlescrew (Pic 010, blue arrow) is attached with one end. The other end is attached to Cable “M” which goes down to the Ensign Staff Lug Ring where it is attached with a simple loop.
The bottlescrew in the Lower Aft Lug Ring puts tension on Cable “M, and by doing this, it also relieves the tension of MC1&4 on the Crane Mast in Crane-tip Nr 12.

Insulator Count
Take a look at the 5 different locations where Brown Ball Insulator-pairs are installed in Pic 001-003-004-005 and certainly in Pic 006.
Total amount of Insulators used in this Rigging step : 10 Brown Ball Insulators

This is the end of step 06.00. Rigging MC1&4 above the Stern up to the Ensign Staff.
This is also the end of Main Chapter 06. STERN.
And this last rigging step concludes all the chapters of the Yamato Rigging Guide.

Thanks for your attention.

Gentlemen,

have a nice day.

Thanks Katana.

I'm looking precisely for the hardware that is holding the wires down on the hull (where they attach). A lot of these are turnbuckles hooked down to an eyelet, some are just run through an eyelet and attached elsewhere. The ropes are run through pulleys and tied down. The wires with insulators (tube type) i'm not sure about how they attach when hung to other wires and the ball insulators are looped and twisted around glass balls, but I don't know how those wires hook into the hull or elsewhere. I maybe missing things, so I have to go through the photos again and look closer. You have cover most of this in the guide.

I have the 1:200 Gallery Yamato kit with the Pontos Detail up set. This kit is large enough that rigging hardware could possibly be 3D printed along with any other parts needed to add more realism to the build. I just don't want to glue rigging wire or line down like all other modelers are doing. It looks tacky.

With your rigging guide modelers now have an accurate reference to know where all the lines go. I'm trying to better understand how everything falls into place. I was hoping that somewhere in Rob Woods photo collection that he would have photographed all the small hardware in what he had shot while doing his walk around. It's possible while he was doing a specific subject that some of this also appears in the photos.

Years ago I contacted Rob Wood asking for such photos knowing he seemed to cover just about every inch of the ship, but I believe he was moving and mentioned he would get back to me in the future, but never heard from him.

Any further photos you can find would be appreciated

Thanks again!

TIA

Jim

CHAPTER 05. AFT SHIP
Step 05.05. Rigging Cable from Side Mast tips to Second Level Deck

Gentlemen,
Today we will talk about Cable”C” that comes down from the port and starboard Side Mast tip Lugs Nr 0 to the attachment Lug Nr 7 on the second level deck of the Aft-Ship.

Let’s take a look at the pictures :
Pic 001 : this is the schematic drawing used in all the rigging steps of the Aft Ship. In this step, the next items are of interest : Startpoint Nr 0 at the Side Mast tip Lugs, Cable “C” and lug Ring Nr 7 on the second level Deck. All on port and on starboard side.
Pic 002 : this is a general overview of starboard Cable “C”( yellow arrows), from startpoint Nr 0 ( blue arrow) at the Side Mast tip Lug, almost vertically down to the second level Deck, where it’s attached to Lug Ring Nr 6 ( light blue oval) with a bottlescrew. Also note the 2 black ovals near the Side Mast Tips and near the second level Deck. They each contain 2 Brown Ball Insulators that are installed on Cable “C”.
Pic 003 : Detail picture of Cable “C” where it arrives on the second level deck. Please note the detail of the bottlescrew and the 2 Brown Ball Insulators.
Pic 004 : View of the same area on Port side.
Pic 005 : general overview on starboard side of a big part of the rigging cables of the Aft Ship. Not only Cable “C” with the Bottlescrew and Insulators is visible but also the 155mm Gun antenna Brackets with all their incoming cables, the connection cables to the AAA Front Brackets and the “Loose Cable G “ that ends on the vertical wall under the starboard AAA platform.
Pic 006 : Detail view of the same area. Please note the location of the 2 Brown Ball Insulators and the Bottlescrew that is attached to Lug Ring Nr 2 on the second level Deck.

Rigging procedure .
Let’s start. Take Pic 002 as a reference.
At startpoint Nr 0, Cable “C” departs from the 2 Side Mast tip Lugs. A little bit further on the cable, we meet 2 Brown Ball Insulators. From there, cable “C” proceeds towards the second level Deck. Before it arrives there, we meet another 2 Brown Ball Insulators. Little after the Insulators, Cable “C” is attached with a Bottlescrew to the Lug Ring on the second level Deck.
Details of the Starboard Bottlescrew and the Lower Brown Ball Insulators are emphasized in Pic 003.

Insulator Count
In Pic 002, you notice there are qty = 4 Brown Ball Insulators installed on the starboard Cable “C”.
This means that on the Port Side Cable C there are also qty = 4 Brown Ball Insulators installed.
Total of insulators used in this rigging step : qty = 8 Brown Ball Insulators.

This is the end of step 05.05. Rigging Cable from Side Mast tips to Second Level Deck
This is also the end of Main Chapter 05. AFT SHIP
Next Main Chapter : 06.STERN
Next Rigging Step : 06.00. Rigging MC1&4 above the Stern, up to the Ensign Staff.

Gentlemen,
have a nice day.

Hello Jim ,

The 01.01. photo 07----------> found it in my stash : see annex

the 01.01. photo 10 is from Rob Wood

The 01.04 photo 02 ------------> also from my stash : see annex

HTH but maybe it's much easier if you could describe what precisely you are looking for.
I have a database where the pictures are sorted by subject. Comes in very handy , sometimes ....

Greetings,
Katana

Katana,

Most of the photos are in Chapter 1 + 2.

01.01 Photo #7, #10

CHAPTER 05. AFT SHIP
Step 05.04. Rigging Loose Cable from AAA platform bracket Nr 5 to Structure Wall Lug Ring Nr 6

Gentlemen,
Today we will talk about about the 2 single, loose cables that run from the port and starboard AAA platform Brackets Nr 5 to Lug Ring Nr 6 that is attached to the vertical structure wall under each AAA Platform.

Take a look at the pictures : they give you details from different angles.
Pic 001: this is the schematic drawing used in all previous rigging steps of the Aft Ship. For this rigging step the next items are of interest : Cable “F”&”G” , bracket Nr 5 and lug Ring Nr 6. All on port and on starboard side.
Pic 002: Is a Port Side detail view of the loose wire trajectory from Bracket Nr 5 to the ring Lug Nr 6, in the structure wall, under the port and starboard AAA platforms.
Pic 003: Starboard side view with detail of the starboard trajectory of the loose cable.
Pic 004: General starboard view that gives you a good idea about dimensions and proportions of the cables and AAA platforms.
Pic 005: Angle-view with starboard detail of the loose cable.
Pic 006: Port side view with detail of the loose cable trajectory.
Pic 007: Close -up of the starboard loose cable.
Pic 008: Port side view with detail of the loose cable trajectory
Pic 009: Starboard side view with detail of the starboard trajectory of the loose cable.

Rigging procedure
This rigging step will be a simple one.
On both Brackets nr 5, cable “G” is attached and from there it goes under the port and starboard platforms where it is attached with a Lug Ring Nr 6 to a ring on the vertical structure wall.
The lug ring is located quite high above a vent. See Pic 007 for detail and the other pictures for general view.
Although Cable “F”, coming from the Side Mast tips is present on all pictures I would like to note that Cable “G” is certainly not an extension from Cable “F”. Bracket Nr 5 is the end station of Cable “F” and also the place where the new Cable “G” starts.
This chapter received its name because the 2 cables in this rigging step are really hanging “ loose”.
When you observe these cables you will see that they are not attached to any other station on the aft ship and they have no insulators installed. One may wonder what the added value is to install a short, loose cable without insulators and which makes no contact with any other rigging device.
Another subject for the long list of Yamato’s rigging mysteries….

Insulator Count
All the pictures show you clearly that in this rigging step, no insulators are used.

This is the end of step 05.04. Rigging LOOSE Cable from AAA platform bracket to lug in Structure Wall
Next Rigging Step : 05.05. Rigging 2 Cables from Side Mast tips to Second Level deck

Gentlemen,
have a nice day.

Hi Jim,
I have no problems to look for them, but it would make things much easier if you could give me the chapter and the picture Nr.

Greetings ,

Katana

Katana,

With all the Yamato Hiroba 1/10 photo collections you have including the Rob Woods set, are there any that have closeups of the rigging hardware? I can zoom up on some of the photos, but it would be better to have isolation photos of this stuff. In the past you have posted some of them here, but some have not been included so far. A full collection would allow someone to 3D print them in the future.

TIA

Jim

CHAPTER 05. AFT SHIP
Step 05.03. Cables to AAA Platform Front Railing Brackets

Gentlemen,
Today we will talk about the cables that arrive in the 2 AAA Platform Front Railing Brackets.
For clarity : the front railing of the AAA platform faces the Aft side of the ship. Good to know when you study the rigging of a ship…

Let’s take a look at the pictures list:
Pic Nr 001: This is the schematic reference picture that will be used in all the rigging steps of the Aft Ship. The elements of todays rigging step are : cables D&E, Branches Nr 2&3, Joint Nr 4, cable F, cables” J”&”K“and joint Nr 5 on the Front Bracket.
And of course : all these items on port and on starboard side.
Pic Nr 002: Side view of AAA platform with detail view of the incoming cables on the port side front bracket.Pay attention for the port side bracket Nr 5: the green arrows mark the Bracket Lugs where cables” F-J-K” are attached. Also clearly visible: the length of the rod between the platform wall and the lug-eye. Quite long!
Pic Nr 003: Upper Side view of port & starboard AAA platform, also with detail of front brackets. In this picture also, the big length of the bracket rod is prominently shown.
Pic Nr 004: Close Head-on view with incoming cables and detail of the 2 front brackets.
Green arrows: bracket Lugs where cables “F-J-K” are attached. Yellow arrows: attachment points ( 2 per bracket) where the triangular shaped support rod is welded to the Platform Wall.
Please note the 4 Brown Ball Insulators near Antenna Brackets 2&3 on port and starboard side of the antenna.
Cable “F” comes from joint Nr 4 that merges the 2 short cables coming from branches Nr 2&3 on cables “D&E”. See also Pic 001 for detail.
Pic Nr 005: Upper aft view of the starboard platform with cables and bracket.
Green arrows: bracket Lugs where cables “F-J-K” are attached.
Pic Nr 006: Starboard view of platform & cables.
Green arrows: bracket Lugs where cables “F-J-K” are attached. Yellow arrows: attachment points ( 2 per bracket) where the triangular shaped support rod is welded to the Platform Wall.
Pic Nr 007: Close -up of Pic 006 : Front-side view of platform & cables.
Pic Nr 008: Front view with detail of incoming cables. Please note the angles with which both Cables “ F” arrive on the front bracket lugs.

Let’s start the rigging procedure :
The Aft AAA platform is located between the Rear Range Finder and the Aft 155mm Gun. See Pic 005. The platform floor is slightly higher than the top of the 155mm Gun roof and it is surrounded by a metal wall. See Pic 002. The metal wall is only the lower half part of the railing because above, on the outside of the metal wall, a vertical railing is attached. See Pic 002.
Caution : the front railing bracket which we will discuss in todays rigging step is no part of that vertical wall-railing!
Outside on the platform wall, a smaller, horizontal railing is attached, much lower than the original railing.
At the underside of that horizontal railing, the 2 front brackets are welded to the metal platform wall. See Pic 002-003-004-005-006-007 for detail.

The platform bracket:
This is a solid long rod (see Pic 002 for detail) with a lug-eye on one end. The other end, the flat side, is welded to the platform metal wall. A second solid rod, bent in a triangular shape serves as bracket support and is welded with its tip to the underside of the long rod and with its 2 flat ends to the platform wall. (see Pic 004 for detail).
The location of the 2 brackets is at the front side of the platforms, but not in the middle. (see Pic 004 for detail).
When you look at Pic 003, you will notice that the 2 brackets are installed rather on the front Outer side, than on the middle of both platform walls. The 2 brackets are facing the stern side of the ship.

The incoming cables :
Each platform front bracket Nr 5 receives 3 cables: See Pic 001-002-003-004-005-006-007 for detail.
First cable ”F” : (see Pic 001 for detail). Above on the Aft Ship, rigging cables “D&E” are split at Branch Nr 2&3 into 2 short cables. Little further, these 2 short cables are immediately brought back together in joint Nr 4, where cable “F” (blue tag on port side and yellow tag on starboard side) emerges and lead to the port & starboard lug-eye of the 2 front brackets Nr 5.

Second cable “J”: from the 155mm Gun Antenna bracket Nr 2 (red & green tag), cable J leads to the lug-eye on port & starboard front brackets Nr 5.
Third cable “K”: from the 155mm Gun Antenna bracket Nr 3 (red & green tag), cable K leads to the lug-eye on port & starboard front brackets Nr 5.

Insulator Count
In this rigging step, no Insulators were used.

This is the end of step 05.03. Cables to AAA Platform Front Railing Brackets
Next Rigging Step : 05.04. Rigging Loose Cable from AAA platform Front Brackets Nr 5 to Structure Wall Lug Rings Nr 6.

Gentlemen,
have a nice day.

Hello Jim,
my pleasure.

Have no idea at all about the PDF 's. I have already made copies from what I published before , but that was done in MS Word files.
Cheers,

Katana

Fantastic Katana. Thanks for all your hard work.

Does anyone know if it's possible to put this in PDF as a complete collection?

Any information would be appreciated.

TIA, Jim

CHAPTER 05. AFT SHIP
05.02. Cables to Aft 155mm Gun Antenna Brackets
Gentlemen,
this is the rest of the pictures.

CHAPTER 05. AFT SHIP
Step 05.02. Cables to Aft 155mm Gun Antenna Brackets

Gentlemen,
today we will talk about the Cables that go to the Aft 155mm Gun Antenna.

The Aft 155mm Gun Antenna Brackets contain not only cables that arrive there, there are also cables that depart from the brackets.
But today we will talk only about the cables that arrive on the Aft 155mm Gun Antenna Brackets. The departing cables will be treated in a future rigging step.

And what else than a collection of detailed pictures can tell you more than 1000 words ?
Pic 001: this is the schematic drawing that will be used in all the rigging steps of the Aft Ship. The following items are important for this rigging step: Cables “D”&”E”, Branches Nr 8&9, Cables “I”-“H”& “B” and Antenna Brackets Nr 1-2-3 , all on port and on starboard side.
Pic 002: a side view where you can see both Side Masts. Please note that cable splits & junctions detail is far more visible on starboard MC4 than its opponent on port side : MC1. Also present & tagged : all cables
leading towards the 6 antenna brackets (green & red Nr 1-2-3).
Pic 003: Front view of the Rear Range Finder with on the foreground the 155mm Gun Antenna with its green & red tagged brackets and port & starboard cables “B-H-I” coming from above. This picture also shows the
linear distance between all brackets.
Pic 004: Right front view of the same area. In this picture you can see where the antenna is installed on the 155mm Gun Roof.Please note the different angles between cables “ I-H” and cable “B”.
Pic 005: Starboard side Aft view of Antenna brackets. Detail in this picture : the lugs that are installed on the aft-upper location of the antenna bar. Again the different angles between cables “ I-H” and cable “B”.
Pic 006: Almost straight head-on detail picture of the Antenna brackets and their cables towards the AAA platform front brackets Nr 5. Also note the prominent presence of 4 brown ball insulators on cables “H&I”.
Pic 007: Port Side view of the same area. Very distinctive in this picture : look at the angle with which cables “H&I” arrive at the brackets, with their 4 brown ball insulators. Also note that the antenna brackets are
located a little bit higher than the AAA platform front brackets.
Pic 008: Port Aft Side view of the Antenna. In this picture we notice the location of the AAA platform front brackets : not in the middle but more on the outside of the platforms. Also the angle with which port and
starboard cables “B” arrive at the anntena.
Pic 009: Bigger view from the same position as Pic 008. This picture shows you the difference of arriving angles between cables “B”, coming from the aft Side Mast tips and cables “H&I”, coming from junctions Nr 8&9 on
Cables “D&E”.
Pic 010: Big side view to show the trajectory of port & starboard cables “B” and the location of the 2 brown ball insulators ( see blue circles) near the Side Masts.
Pic 011 is the schematic drawing with all cables arriving at the Aft 155mm Gun Antenna.

Let’s start this rigging procedure :
In all the pictures of the 155mm Gun Antenna , the 3 port brackets are marked red and the 3 starboard brackets are marked with green colour.
Numbering of the brackets is, like so many items in the Yamato rigging, done in mirror view.
In plain English: both brackets Nr 1 are located on the OUTside of the antenna, brackets nr 2 are in the Middle and brackets Nr 3 are installed on the INNER side of the antenna, facing each other.
Notice : not only the Antenna Brackets are identified in mirror view, the locations from where the incoming cables originate are also a mirror view from each other.
There are 2 different sources that “provide” the antenna brackets with cables : startpoint 0 on the 2 Side Mast Aft Lugs and cables “H&I” (port and starboard side) above the Aft Ship.

Starpoint Nr 0 at the 2 Side Mast Aft Lugs.

On both Side Masts, the Aft tip Lug is considered as startpoint Nr 0.
From there, cable “B” departs and immediately encounters a brown ball insulator not far from the Mast tips.
See blue circles in Pic 002 & Pic 010.
Then, both cables “B“ (blue tag for port side, yellow tag for starboard side) lead to the red and green tagged outer brackets Nr 1 on the antenna. See detail in Pic 003-004-005-006-007-008-009.
Antenna brackets are in fact big lug rings that are attached on the upper aft side of the antenna bar. Very suitable to fasten cables. See detail in Pic 006 & 007.

Cables “H&I” at port & starboard of the Aft Ship rigging.

Cables “H&I”emerge from junctions Nr 8&9 with blue tagged cables “D&E” on port side and the yellow tagged cables “E&D“on starboard side, high above the Aft Ship. They lead to the red & green tagged brackets Nr 2&3 on the 155mm Gun Antenna.
See detail in Pic 001 & Pic 002.
Here are the interactions between the cables “D&E“ ,junctions Nr 8&9 (port & starboard) and the antenna brackets :
In Branch Nr 8 on Port side cable D, cable “H” goes down to the red tagged Bracket Nr 2 on the 155mm Gun Antenna.
In Branch Nr 9 on Port side cable E, cable “I” goes down to the red tagged Bracket Nr 3 of the Aft 155mm Gun Antenna.
In Branch Nr 9 on Starboard side cable E, cable “I” goes down to the red tagged Bracket Nr 3 of the Aft 155mm Gun Antenna.
In Branch Nr 8 on Starboard side cable D, cable “H” goes down to the green tagged Bracket Nr 2 of the Aft 155mm Gun Antenna.
With al this info, we know which cables arrive in the 6 Antenna Brackets and where they come from.

Remark :
We know there are qty=4 brown ball insulators near the Antenna brackets Nr 2 & 3 of the Aft 155mm Gun. It’s maybe worth to compare this with the lay-out of the Front 155 mm Gun…
If you look back at rigging chapter “01. FORESHIP 04. Rigging Antenna Wires to Front Bridge Structure” published on 19 march 2017, you will discover that on the Front 155mm Gun Antenna there are qty = 4 White Bar Insulators used instead of the 4 brown ball insulators on the Aft Antenna. Quite a difference !

Insulator Count
In this rigging step we see on port & starboard side of the antenna :
qty= 1 brown ball insulator on cable “B” at startpoint 0, near the Side Mast tips.
qty= 1 brown ball insulator on cable “I” near bracket Nr 3 on the Antenna.
qty= 1 brown ball insulator on cable “H” near bracket Nr 2 on the Antenna.

Each process is applied on port and on starboard side.
Total amount of Insulators used in this rigging step = qty 6 brown ball insulators.

This is the end of step 05.02. Cables to Aft 155mm Gun Antenna Brackets
Next Rigging Step : 05.03. Cables to AAA Platform Front Railing Brackets

Gentlemen,
have a nice day.

CHAPTER 05. AFT SHIP
Step 05.01. Main Cables Nr 1&4 Double Splits & Joints above the Aft Ship

Gentlemen,
Today we will talk about the double splits and joints on Main Cables Nr 1 & 4. (MC1&4)
The last time that MC1&4 were discussed, was in step 03.01. “Rigging of MC1&4 from Bridge Main Yards to Side Mast arm Tips”.
In that specific rigging step we saw that MC1&4 departed at the Bridge Main Yards and arrived at the Front tip Lug on both Side Masts.
In todays rigging step, MC1&4 depart from the Side Masts Aft tip Lugs (port & starboard) towards the Crane-tip on Yamato’s Stern.
But before they arrive there, a lot of structural changes will be part of their journey.
Notice :
As a reference I use 2 schematic drawings : pictures 001 & 002. They served in rigging step 05.00. but their contents & info are suitable for this rigging step.
As regards to Pic 003 - 004 & 005: Not every picture shows the same kind of details. Let me explain:
Pic 003 is a rear view picture that shows you very well the proportions of MC1&4 towards the Mast beams. It also shows the individual dimensions and distances between Split Points Nr 0-1-2-3-4-8-9 and the 2 brown ball-insulators near start point Nr 0 (yellow circles).
Also distinctive in this picture: the departure points of Port Side Cables D-E-F-H-I. On the other hand : the starboard cables and split points are very hard to discover, due to the Black back-ground colour of the Funnel. But when you use your zoom, you may find them.
Pic 004 is a SIDE view picture that I introduced with only 1 goal: to show you the dimensions and proportions of all cables on MC1 &4 above the Aft ship.
When you look very close at this picture you can see :
a)the individual dimensions and distances between Split Points Nr 0-1-2-3-4-8-9.
b)the dimensions of all the cables that come down to the deck.
c) the relative position of the split points & cables towards the Aft AAA platform, the 155mm Gun Antenna and towards the Gun Barrels. Important : the yellow striped line, marked with Red arrows shows you MC4 Joint Nr 10 that indicates the end of cables D&E but also the left end of the Aft Ship Rigging Area. And it also shows you the vertical position of the rigging area towards the barrels of the 46cm Aft Gun Barrels.
d)the arrival of cables on the AAA platform Front Railing Brackets and the cables reaching the 155mm Gun Antenna : they are clearly visible in this picture but in a side -view they loose too much detail to be numbered or tagged.
Pic 005 is a Side view, ideal to show you the distance between MC 1&4, and the dimensions & proportions of the Aft Ship cables.
This picture was used to show you detail of all the split points, joints and cables near the Side Masts.
What you didn’t see in Pic 003 & 004, but what is exposed and colour- marked & numbered in this Pic 005 : the arrival of the 2 cables ”F” on the AAA platform Front Railing Brackets (joint Nr 5). Also marked: the arrival of the cables (B-H-I) on the 155mm Gun Antenna, on port and starboard side. In this picture, certainly MC4 lends itself better to show details of the Aft Ship Rigging. Due to the capture angle in this picture, MC1 is not that suitable.
So far the list of what is different in pictures 003-004 and 005.

What is common in the pictures and drawings : I used the same Colours, Branch Nrs, Split Point Nrs and Cable Letters.
Much easier to compare details from pictures with the schematic drawings and vice-versa.
Before we start, I would like to emphasize on a subject that will be used in this rigging step : The “ Triangle Branch / Joint”.
This device is in fact a cable split- or branch where the original incoming cable is duplicated from a single into a double one.
Not far from the split point where the incoming cable is duplicated, a solid rod is attached perpendicular between the 2 cable members. That’s the reason why this particular Branch looks like a “Triangle”.
Typical for a Triangular Branch is that the distance between the 2 cables remains constant untill another triangle is installed and the opposite procedure is applied. When the 2 cable members arrive at the second rod, short after, the 2 cables are merged back together to form 1 single Cable. In our case: MC1 or MC4.
One can say that a Triangular Branch is the opposite, or the mirror view of a Triangular Joint: and this is exactly what happens above the Aft Ship on Yamato with MC1 and MC4.

Let’s start.
In chronological order this is what happens with MC1&4 above the Aft Ship:
Main Cables Nr1&4 depart, at the Side Mast Aft tip Lugs in
startpoint Nr 0. Near the start points , both cables run trough a Brown Ball Insulator. Not far from the Side Masts, MC1& 4 reach Branch Nr 1, where they are split via a triangle branch into cables D& E. These Cables continue their way to the Crane-tip on Yamato’s Stern.
Immediately after Branch Nr 1, we meet Branch Nr 2 & 3, where 2 short cables are attached to cables D&E. The short cables are brought together in Joint Nr 4. In Pic 003 and 005 you get a good view how close Branch Nr 2&3 is located near Branch Nr1.
The same goes for Joint Nr 4 : the cables that extend from Branches 2&3 are quite short and Joint Nr 4 is installed right after the short cables.
Out of Joint Nr 4, Cable “F” emerges and goes down to the bracket Nr 5 on the Front Railing of the Aft AAA Platforms.
On Cables “D”&”E”, not so far behind Branches Nr 2&3, we encounter 2 new Branches: Nr 8 & Nr 9.
From here, 2 new cables emerge and go down to the Brackets on the Aft 155 Gun Antenna. The same process takes place on port and starboard side, but in Mirror View.
Please check the cable names and Joint nrs in Pic 003-004 & 005.
From Branch Nr 8 & 9, Cables D & E ( port side) and cables D& E (starboard side) proceed to the crane tip on the stern. Above the 46cm Gun, little before the end of the barrels, cables D&E are back joint into MC1 & MC4 in Cable Joint Nr 10.
From Cable Joint Nr 10, MC1 & MC4 resume their way to the crane tip on the stern.
So far the MC1 & MC4 double cable splits above the Aft Ship.

Insulator Count
We see 2 brown ball insulators : one on MC1 and one on MC4 near the Side Masts. See yellow circles in Pic 003 and red circles in Pic 005, both near start point Nr 0.
Pic 002 shows you the schematic position of the insulators on MC1 & MC4.
Total amount of Insulators used in this rigging step : Qty = 2 Brown Ball Insulators .

This is the end of step 05.01. Double Splits & Joints of Main Cables Nr 1 & 4 above the Aft Ship
Next Rigging Step: 05.02. Cables to Aft 155mm Gun Antenna


Gentlemen,
have a nice day.

CHAPTER 05. AFT SHIP
Step 05.00. Aft Ship Rigging

Gentlemen,
Just like in other Main rigging chapters, this first article will be a fairly general one, without too much details. Details will be discussed in their appropriate future rigging steps.

Today we will talk about the Rigging on the Aft Ship.
I will explain you where the Aft Ship area begins and where it ends.
Rigging on the Aft Ship mainly includes all the Splits , Branches and Joints that are applied on Main Cables Nr1 & 4, from the Side Mast Arms, up to the area right above the Aft 46cm Gun Barrels.
Also in this Main Chapter: we will talk about Connecting Cables between MC1&4 and the AAA platforms, Structure Wall and the Aft 155mm Gun Antenna.
Pic 001 is a schematic drawing (not to scale), of all the cables and locations that are involved in the Aft Ship Rigging. Please use your ZOOM.

Nr 10 Triangular Joint = location where Cables D & E merge back into 1 cable : MC1 that proceeds to the Crane tip on Yamato’s Stern.

Yellow highlited Letters (Starboard Side) & Digits

MC4 = Main Cable Nr 4, departing from starboard Side Mast Aft tip Lug Nr 0.
Triangular Branch Nr 1 = location where MC4 is split into cables D & E.

A schematic drawing has the benefit it can show you a very large amount of data in a very limited space. The disadvantage is that the amount of data can be overwhelming.
That’s why Pic 001 may be usefull to show you the complete Aft Ship Rigging stuff, but it still uncomfortable to read or understand.
To resolve this problem, I retrieved my old Pic 002. This is a side view drawing of the Aft Ship Rigging that uses the same colour codes, letters and digits as Pic 001.
In Pic 002, the schematic factor disappears and is replaced by a more practical drawing. It shows you a realistic view on each specific location of Main Cables, Branches, Joints and Connecting Cables on the Aft Ship.
Nevertheless, Pic 002 has also its limitations : in the side view there was no opportunity to show Cable “G” on port and starboard. Nor did point Nr 6 show, where Cable “G” is attached to the Structure Wall under the Aft AAA platforms. And instead of seeing 2 Aft AAA platforms and 2 Brackets Nr 5, you see only 1 piece because this is simply : a Side View.
What is also missing in Pic 002 ? Cable “C” that runs from the Side Mast Rear tip Lug to the second level deck where it is attached to the deck with a bottlescrew in attachment point 7.

However, there still 2 items in Pic 002 that are of some interest to Us.
The first one is the expanded screen that shows the Aft 155mm Gun Antenna and the arrival of 6 cables on its Brackets.
The scaled-up Antenna view shows you more details than the small original figure in Pic 002.
The second interesting item in Pic 002 is the red coloured line at the left side of the picture. This red line marks the Rear limit of the Aft Ship Rigging area.
The marking point for that limit is visible in the upper part of the picture. The red line starts at the left side of Joint Nr 10, where Cables “D & E” merge back into 1 single cable, namely : Main Cable Nr 1 on Port side, but also Main Cable Nr 4 on Starboard side.

To compare the schematic drawings with a real picture , I introduced Pic 003 to give you an idea about dimensions.
At the right side you see start point Nr 0 on the Port Side Mast where Main Cable Nr 1 departs.
A little further to the left, and due to the Triangular Branch Nr 1, MC1 splits from a single cable into 2 cables.
From there, they proceed to the Crane tip on the Stern.
At the outer left of Pic 003, in Triangular joint Nr 10, the 2 cables are merged together into 1 single Cable: Main Cable Nr 1. Near this location you also see the red striped line, marked with red arrows.
When you pull the red line down to the deck, you end up above the 46cm Gun Barrels, little before their end.
Although the starboard Side Mast tip is not visible in this picture, Pic 003 shows you where the Aft Ship Rigging begins (start point Nr 0) and where it ends at the vertical red line, near Joint Nr 10.

This area is the playground of all the next rigging steps on the Aft Ship.
Remark : in all next rigging steps on the Aft Ship we will use the same colours, letters and digits for the mentioned rigging devices.

Insulator Count
Needless to tell you that in a general rigging step like this one there will be no insulator count.

This is the end of step 05.00. Aft Ship Rigging
Next Rigging Step : 05.01. Main Cable Nr 1 & 4 double Split above the Aft Ship

Gentlemen,
Have a nice day.

CHAPTER 04. REAR RANGE FINDER
Step 04.06. Cables from RRF Brackets Nr 2 to Side Masts Upper Lugs

Gentlemen,
Today we will talk about the Cables from RRF Brackets Nr 2 to the Side Masts Upper Lugs.
Remember the Side Masts Upper Lugs ?
The description in rigging step 03.00. Mast Assembly Part 2 says : “The Side Mast Upper Lugs are located on both Side Masts, slightly under the (white cord) triangles and also little under the connection of the Side Mast Arm with the Upper Reinforcement Triangle See Pic 031“. This “pink circle in Pic 031” from step 03.00. is in this rigging step 04.06. : Pic 005 station “J “.
The picture is the almost the same. The name tags differ.

Let’s take a look at the pictures in this rigging step :
the picture colour codes:
Yellow arrows : port side cable trajectory.
Light-or dark blue arrows: starboard side cable trajectory.
Yellow circles : port side Brown Ball Insulators.
Light-or dark blue circles : starboard side Brown Ball Insulators.
E : port Side Masts Upper Lug.
J : starboard Side Masts Upper Lug.
Yellow tag Nr 2 : port side RRF Bracket Nr 2.
Light-blue tag Nr 2 : starboard side RRF Bracket Nr 2.

Recommendations when using the pictures :
Use your zoom to distinguish the different cables. Before I have put arrows on them, I enlarged the pictures quite a bit to know the exact location of the 2 cables in this rigging step.
Beware of optical illusions : At a certain location in Pic 008, our cables run very close to the White Cord that goes to the Side Mast Triangles. Just follow the arrows and use your zoom to find the exact cable. The Brown Ball Insulators near the RRF Brackets are not always clearly visible. But when you look for the Blue or Yellow circles, you’ll find them.

Pic 001: as always, this is a schematic drawing adapted to this rigging subject. You see at port and starboard side 2 cables that depart from the RRF Brackets Nr 2, they go upwards to the Side Masts Upper Lugs where they are attached.
Beside Pic 001 there are 7 other pictures that show views from different angles on the cable trajectories, the Side Mast Upper Lugs and the RRF Brackets.
I recommend you to use the picture colour code when you look at them.

Rigging procedure :
From both the port and starboard side RRF Brackets Nr 2, a cable departs to the Side Masts Upper Lug. See Pic 002-003-008.
Details of the starboard Side Mast Upper Lug can be seen in Pic 004 & 005.
The port Side Mast Upper Lug is shown in Pic 006 & 007.
And although Pic 008 is quite dark, both cables can be easily distinguished, despite the dark back-ground.

Insulator Count
Notice :
From all the rigging steps in Chapter 04. REAR RANGE FINDER, this is the only one where Brown Ball Insulators are used.
The Brown Ball Insulators are installed per pair on each cable. See Pic 002 -003-008 for details : the first pair is located a little lower than the Side Mast Upper Lugs. The second pair Insulators can be found on the cables right before their end-station in the RRF Brackets Nr 2. There are 2 cables with 2 pairs of Brown Ball Insulators.
Total amount of Insulators used in this rigging step : qty = 8 Brown Ball Insulators.

This is the end of step 04.06. Cables from RRF Brackets Nr 2 to the Side Masts Upper Lugs
This is also the end of Main Chapter 04.REAR RANGE FINDER.
Next Main Chapter : 05. AFT SHIP
Next Rigging Step : 05.00. Aft Ship Rigging

Gentlemen,
have a nice day.

CHAPTER 04. REAR RANGE FINDER
Step 04.05. Cables from RRF Brackets Nr 3 to the Upper Triangle Aft Beam

Gentlemen,
Today we will talk about the cables from the port and starboard side RRF Brackets Nr 3, up to the attachment Lugs on the Upper Triangle Aft Beam.
The Pictures :
Pic 001 is a simplified schematic drawing , adapted for this specific rigging step. It shows you both RRF Brackets Nr 3 and the 2 cables that go upwards and end in the rear connectors of 2 White Bar Insulators that are attached to the Upper Triangle Aft Beam Lugs.
Pic 002 is an aft view on which you can see the cable ( yellow arrows) from Port side RRF bracket Nr 3 towards the White Bar insulator installed on attachment “F” on the Upper Triangle Aft Beam Lug.
The trajectory of the starboard side cable (light blue arrows) from attachment “I” on the Upper Triangle Aft Beam Lug to the RRF Bracket Nr 3 is visible on the starboard side.
The yellow and light blue colours apply also to the arrows and Bracket tags in Pic 003 & 004.


Rigging procedure :
In fact this rigging step is quite similar with step “04.04. Rigging cables from RRF Brackets nr 4&2 to the connection line between the 2 Side Mast arms”. And it is also pretty simple.
The 2 cables depart at the port & starboard RRF Brackets Nr 3 and go upwards to the aft connectors of the 2 White Bar Insulators that are attached to the Upper Triangle Aft Beam Lugs.
That’s it. No complications , no special devices or whatsoever.
The port side cable is attached to a White Bar Insulator on the port side of the Upper Triangle Aft Beam and the starboard side cable is attached to a White Bar Insulator on the starboard side of the Upper Triangle Aft Beam.

Insulator Count
We see 2 White Bar Insulators that are used on the Upper Triangle Aft Beam Lugs : one on port and one on starboard side.
Total amount of insulators used in this rigging step : Qty = 2 White Bar Insulators

This is the end of step 04.05. Cables from RRF Brackets Nr 3 to the Upper Triangle Aft Beam.
Next rigging step : 04.06.Cables from RRF Brackets Nr 2 to Side Mast Upper Lugs

Gentlemen,
have a nice day.
