Only a master of his craft can make a build like this look straight forward.
You've got me hooked.

Hi Richard how are you. How's the Kirov? I will be the first to admit there are many parts in the Kashtan that i have no idea as to what they are for but If where looking at it as a resin /PE build then I have some thoughts as to which will be resin and which would be PE.

Hello Paul I think you use the same approach for building those radar mattress arrays. We all seem to evolve methods that cope with the materials we use the most .I am in awe at ARH and the way he can manipulate Litho, in large amounts to achieve the results be wants. keep up the build I will be looking forward to seeing more

Tutorial time--------------

Ok the next set of steps involves the area marked D in this drawing , which supports the optical tracker . I am unsure as to whether it or the tracker or both are able to rotate up and down .

On the inboard side is a series of ribs which are simulated using 1mm x .25 styrene strip .
The loose ends are removed.


This �rotating� support for the optical tracker �D� is fitted to A .


A section of 10mm styrene tube is used to form the drum which separates D from A
{ As a foot note this was later modified as the width of 4.5mm was reduced to 3mm. The reason being as overhang went to far as to interfere with the rotation of the gun }


In this picture you can see the inboard edge of section D and the top cover of litho has been fitted to section A .


The work thus far where all that has been discussed is fitted {temporarily as more detail needs to be added and it�s best to undertake this separately ] into place with the optical tracker also temporarily fitted onto section D


Looking towards section B


Gun barrel mountings

Moving on the construction of the business end of this weapons fit , the guns.
I mulled over as to how I was going to build each of the barrel mountings . Originally I thought of following the same pattern as the other fittings and build the barrel mounting from separate parts but I noticed that the barrel end was chamfered slightly .


Fortuitously |Evergreen came to the rescue and produce a box section that was better that I could have hoped for .

I leave you with this until next time ----

Your work is breathtaking !

[Cadman]

Amazing work Dave. I love the small details.

[Ticonderoga]

Hi Dave, just spotted the thread , been away for a little while

I know Mick has already asked about dimensions, but what scale are you working in? Looks a bit small for 1/72, buT then again it could be my yes.

Thanks a lot Dave for doing this I appreciate it. Will make my life a bit easier soon

Dave
Your work is breathtaking !

Hi Richard Thanks for looking in. Like yourself I do my best to see a build not as a single item but a series of defined parts ,a jig saw is probably a better definition .In that way even the most problematic of fittings can be made. The down side is when building an entire model it takes twice as long as it should.

Amazing work Dave. I love the small details.

Hi Cadman I'm just delighted that I can show a little bit of "How to". To be fair I have yet to add the detail to the rear of the Kashtan but to be really candid there is an ellement of modellers licence in this build , I guess with out that licence and not having all the facts - detailed pictures and so on I really would be unable to build the model.
here is the next generation of the same gun , the Palma , less in the way of "bits"
Thanks for looking in

Hi Andrew I trust you are now rested and ready. Workshop is ready especially as you have a serious contender for your modelling time in that huge Kirov?
I know I was hooked on 1:144 for a long time but the kashtan is, thankfully at 1:72 even though my faithful Humbrol tin says it looks smaller. "How do I know that�, well using a 1; 72nd drawing of Steregushchiy and with the help of some pictures the rest is down to a bit of old fashioned geometry . I have a confession I am clueless about CAD

Dave, What ship???

[Dave Wooley]

Hi Mick Thanks for looking in . The ship with the Palma looks like Project 1166.1 Gepard 3.9 [ export version}


Dave Wooley

[Neptune]

Indeed, the Vietnamese version. Some very handsome ships aren't they??? I just love them, unfortunately hard to get any plans of those! The actual Palma is also on the new Gorshkov frigates, 2 of them, 1 each side of the hangar. Normally she does have a round head, and I'm not sure if the Gorshkov version will have the missiles mounted?

Anyway, you're diverting, where is the progress of today ? Just kidding, great to see this build-up and I'm still amazed by the speed at which you do it!

[Dave Wooley]

Hi Roel good to hear from you . Yes the Gepard does look a hansome ship .As you say no drawings available , what a pity indeed.
When are you returning to building the grey line?

Tutorial time ---------------

We have the basic barrel mounting which is Evergreen Box section .The next job , using a small �pin vice� { finger drill} is to make an opening into one end. As the barrel is to be painted separately the best idea I could come up with for securing the barrel was to insert a length of aluminium tube into the mounting onto which the barrel would fit. Ok here we go.



With an opening made for a 2mm od tube and the splay as indicated in the picture -------


Just as a reminder there is a left and right barrel mounting as there is a left and right retaining basket either side but more on that at a later stage .

The inner 2mm tube can be inserted into the box section mounting .



The outer barrel is inserted over the inner tube . This also helps when fitting the barrel support.



Progress thus far There are parts to be added to the sides of the barrel mounting.


One each out board face of the barrel mounting is a raised ,splayed section . This is formed from 1.5mm styrene sheet.


This splayed section the same height as the barrel mounting is fitted into place -------- splayed edge facing the barrel .


Fitted to the splayed section is a series of 4 strips and a small 3mm styrene disc made by using a leather punch { I have explained this device in the Kiev build a very useful tool to have in the box If you want me to explain its use please ask}


As the Kashtan is both gun and missile capable there is a series of launch tubes that can be attached to the top of the barrel mounting .


For this build the tubes do not apply however the top does. Unfortunately I have to use a little modellers licence on this one as there does not appear to be really good picture showing this part of the barrel mounting.{ as they say �sods law� will come into play and someone somewhere will unearth the pictures that shows this very spot} .But until that happens it down to modellers license
For this I have used a strip of .50 styrene to match the top of the mounting. Onto that, and fitted either side are fitted 2 lengths of �L� Evergreen section extended by 3mm . it would appear that the inboard L section is trimmed .This has not be done here?


The rear of the barrel mounting looks to be an acess point{ only an educated guess] and this was also included on the model


For the model a panel was cut and shaped to match the end of the barrel mounting.
Onto that a styrene discs was added.


Next stage was to form the bands around the barrel as shown here.


To simulate these bands I used a sticky back trim tape but to ensure the ends where firm a small amount of CA was added .


The result thus far.




Two barrel plus mounting ready to be fitted .


That�s it for now but for next time the two barrel support arms and a start on the side baskets

I wish I could see things as separate items like you do .You brain must function in 3D .

[Dave Wooley]

Hi Richard thanks for looking in. I think it's down to brain training strangely I have had a similar discussion with fellow modellers such as ARH as to how to view and evaluate such items for model making. I think the difficulty arises when there is a complete lack of any drawings then it really is an uphill job. Building the fire tender for Kiev was one example. But the kashtan or for that matter a Bofors 40mm on a Mk 1V mounting are just two of many example of many gun fits where a drawing exists along with photos . This of course makes the job much less problematic. To be honest I can only show how I would tackle the build, as they say there are many ways to skin a cat, no offence to cats here. Builders like John Haynes and the late Paul Beckley are and where true masters of their trade They of course go one step further and use their skills as pattern makers to transfer the prime parts to mouldable items , then reverse the program to make the model fit for assembly by a novice modeller . For me that the true mark of how to create a complex fitting to a much less complex fitting but in resin.

Brilliant work Dave,

Every piece you add is giving life to the gun assembly.

I know it's hard, but don't give in - it's a beauty.
