Building the C A D -N-1 Kashtan air defence gun system

[Song Jung Gun]

Hi Dave!
Your model making methods and results are always supprised me.
You are a master and my teacher.
Thanks sharing photos.
your Song.

Hi Roy resin parts for an entire ship and at 1:700 now that is to my mind much more difficult than the Kashtan . I will be looking forward to Telford to have a little chat regarding this gun . I have no experience of developing such parts for moulding , Thanks for posting your Castle class , food for thought . Any help needed re- the big stuff just let me know .

Hi Norberto my friend I have just finished air brushing the parts for the kashtan . I only use a primer on large areas such a hulls . Small item such as this containing plenty of detail I tend to { not on every small job} restrict the air brushing to a single session . I don't like to much paint as it can hinder the detail where as a limited coating can bring the detail out. I used on this occasion a small White Ensign tin let of Russian Navy Grey , straight out of the tin. Thanks for looking in .

Hi Dave,
i have already purchased the hull, props and motors for a Leeds Castle in 1/72, didn't realise at the time that 1/72 in the UK
is not one of the more popular scales. Mind you a BB in this scale would be BIG, so that probably explains it. Luckily i would rather scratch build than kit build.
will make a start in the spring, so yes please to all the help you can give me.

Hi Song Thank you for very kind comments . I try to evaluate a part , fitting , even an entire model and reduce it to what I perceive are a series of mini builds ,for me this makes difficult subjects manageable . I am still the pupil as I never stop learning. Once every two months I attend build seminars. These are like hot houses for model ship builders no matter what type of model from period wooden ships through to modern day and all the engineering thrown in for good measure. It�s a wonderful experience, to see parts made, machined, moulded, painted all part of a full day seminar. Not that this is stuck in traditional methods there are tutorials on the new art of lazar moulding a technology that is just amazing to watch. Here many of the top modellers share their skill they are the masters I am but one of the students and 8 hours vanishes so quickly.
Here is just one example . Experimental model maker Bill Richardson discovers the workings of leanado de Vinci in his building of a paddle boat from Leonado da Vinci drawings.

Hi Roy It seems that 1:72 is gaining in popularity amongst the modern warship fraternity building the corvette , frigate and destroyer size hulls , simply because they handle better out on the water . If and when I build another carrier I think I'll stick with 1;144 simply because of transport . As mentioned just ask and help will be given

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

The last remaining part of this build is the radar dishes then it�s on to painting and assembly.
For now the radar dishes. The larger of the two arrays was reduced to 10 parts . The material of choice was .50mm styrene sheet.
The basic dish { orange peel parabolloid} consists of the main reflector and the back supports which will be covered over , support structure , feed horn assembly and secondary feed horn at the end of the support frame .
The larger tracking array


The smaller array which contains similar components .


The two supports ready to be fitted to the rear of the dish .These are slightly angled at each end to follow the shape of the outside edge of the dish.


Back supports fitted . it�s noticeable that these supports are shaped to follow the convex contour of the dish.



The covering of these can begin working from the centre.



Progress thus far .


The method of assembly is the same for both arrays as seen here.
From what can be gleaned from looking at the pictures of both arrays they appear to be separated by a section between the housing and the rear of the dish. Once again modellers licence comes into play and I have shown this as simple square sections made from 1.5mm styrene for the large dish to 1mm for the smaller dish.



With the dish prepared the feed horn is fitted to the centre of the dish this is followed by fixing the support arms { .4mm brass for the large dish. .31mm for the smaller dish }


With the two arms fixed { with CA] the secondary feed horn is fitted. Although not exact I have used Evergreen U section to fit over the support arm joint. Fixed to the rear is a short length of .45mm brass to secure the dish into place when painted .



Once again the smaller dish follows the same method of assembly .Only the secondary feed horn differs slightly .


OK the acid test will they fit , yes they do .


Now for air brushing ---------------------

Dave, your attention to detail is amazing. Will it be moveable on the model?

Robert

[Neptune]

It won't be on the model (I hope ).

Some stunning work there Dave (didn't expect anything less though ), and in contrary to what the pictures "seem" to show, this Kashtan is still pretty small!
Something I noticed while building large scale and shifting back and forth with small scale, is that in large scale you start looking at the number of real parts on a device. Like your Kashtan, every piece is really built up like on the real one. In small scale you rapidly leave out things or carve/shape several parts in one piece.

Anyway your way of working and your extremely educative way of presenting it has thought many of us a lot of things, not in the least myself! Thank you for that

Hi Robert although the two gun mountings can move up and down and the gun will rotate, there is no mechanism to do this as a working feature, but it would be interesting especially on the Kirov.

Roel you are very welcome and thank you for your encouragement which you have shown over a long period I appreciate that. Yes it is quite surprising just how small this piece is and the full size kashtan. Even though it's a far cry from 1:144 1:72nd is more difficult than 1:144 as more of the hidden detail becomes essential . Looking at the pictures of the Kashtan there remains a huge amount of minor detail that could be incorporated into the model and if I was doing the gun at say 1:50 then I suspect I would take forever or I would be carted away by the men in white coats before I finished

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

Moving on to the very last task before assembly of the air brushed parts. .
Around each barrel where the barrel emerges from the mounting is a stainless steel ring . The trick is to reproduce this with out painting but achieve more authentic results ?


I find it more convenient if as many of the main parts can be separated for airbrushing .


Just as a brief reminder this is the barrel , mounting and support frame before airbrushing


� Ok questions for this specific job what material or method gets better results than paint�?
Answer sticky back silver tape used by central heating engineers and available in plumbers merchants .


Being very thin it�s easy to cut into any width .


The result is a very fine segment of tape ideal for wrapping around the root of the barrel


I used a discarded length of styrene to secure the strip of tape , then cut to the desired length for the barrel


Fixing could not be easier . As the backing is sticky back the trick is to ensure one end is firmly secure and just wrap the remainder of the tape around the barrel and that�s it !


Well all this effort has to show some results next time the Kashtan as a finished fitting.

very good Dave
the infinity of materials we can use is very big.
i like the results of your gun system.
the mountings are very well executed too.
all scratch in high level

Thank you Norberto always good to see you looking in and for your friendly comments The project is almost completed then i must complete a slightly larger project.

Thank you too Dave we are friends and you have superb quality in your works.

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

Well this is the last segment of this brief but intence turorial on building the Kashtan . I really hope you have enjoyed and perhaps picked up one or two useful tips from this build.
Now with all the painting completed all that remained was to assemble all of the salient parts. In some respects this could be considered the opening phase of the far larger build of the Corvette Steregushchiy. So with out any more chat here is the completed gun .

Just as a sobering reminder if such a reminder was ever needed I will show one again what the Kashtan looked like before any part was measured or cut. That�s what I like about scratch building , the model like a jig saw it's all there but you have to sort out the various bits and make them fit



The Kashtan completed.












Thank you all for looking in on this build and encouraging me.
Dave Wooley
That�s it for the Kashtan

Awesome !!

Dave
No words would do it justice .

[DrPR]

Dave,

Excellent work. And it is a reminder that any ship model is really a collection of models.

[Neptune]

Really nice, now the question remains, will it be used on the model... or not?
