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

[Neptune]

hmm, looking at this progress I'd say you can finish a Stereguchiy in a month or two
Making fast progress here, although I guess, as mentioned before, the aft part is the most complex part and will therefore take a while in research time.
Another question, will you build the actual Stereguchiy Kashtan or will you go for the original Kashtan (with different barrel support and perhaps different backside as well?)?

Dave just got back from a trip and started to have a good look at this post. Could you just go back a few steps and give some dimensions in metric so I could build one also at your size. EG diameter of the disks and pipes. Height of cut. Maybe part A dia. 10mm 1mm thick and so on per picture.

Hi Roel I am still debating as to whether I'll opt for all VLS and build Boikiy. The drawings I have are for Soobraziltelnyy/Boikiy As for this build project I'll keep with the Kashtan as fitted to Stereguchiy. I also noted that what appears to be collectors for spent rounds differ in shape depending on how the Kashtan is mounted ?.
Thanks for looking in

Fear not I will list all the material sizes at the end of the build to avoid confusion.

Thanks for asking

Tutorial time
Building the CAD-N-1 Kashtan modified for the Russian corvette Steregushchiy.

I�ll be moving on to build up the centre support, tracking radar support and the housing for the optical tracker.

The centre support and the two side drums are now fitted together and can be fitted onto the mounting .


To make the build more coordinated the next step is to commence assembly of these three parts which for ease of reference and to simplify I have listed as items A ,B, and C .


Commencing with item A which is the support for part of the tracking radar system .
Each of the pre-cut 1:72nd scale each side is prepared ready to be joined together.

Once joined together the gap can be covered by a strip of .50mm styrene , a simple operation but best bonded with CA
Seen here to the rear of the mounting .


With item A prepared attention can shift to item B .This is ringed in red in this picture.


This fitting is also very simple to make but bearing in mind that there is a recess into the exposed side of the fitting .






The recess in the side for housing electrical boxes is created.






The next fitting is marked as C on the picture but is the optical tracker housing .
Once again the basic parts are cut and prepared for assembly .

When assembled there is a flat section on the top edge .


Progress thus far.

The next job is to start assembly of these basic parts [ all will be explained ] before work on the gun housings and the mass of detail to the rear of the Kashtan !

Just wonderful as always!

Question: when you wrap the thin styrene around the more rigid frames, do you a) glue down one end, bend it around the frame, glue down the other end, then glue the other contact points between or b) glue down one end, then keep on gluing millimetre by millimetre as you wrap it around the frame?

Hello Dave,

Brilliant work mate.

Hi Timmy thanks for looking in. To answer your question I adopt "a" , then irigate from the inside using a fine brush and liquid poly the the unbonded curved section. No CA on this one, get the positioning wrong and it's a throw away job.

Hello Dave my friend
wow very good method to do it.
ilove it, this type i like to do, imagining how we can do the piece and
producing smart platform method.
what scale this piece?
great from you

Norberto good to hear from you . The scale is 1:72 , small yes but at my old scale of 1:144 I'd be pulling my hair out

Lol
well Bismarck have so small pieces to do
sometimes i need to trip to Himalaia to
increase my power

[roy allen]

sharp work, well thought out.
As for pulling your hair out, don't do it trust me. It gets cold without thatch, i should know

Hi Roy good to have met up at the Convention . I guess scratch building a kashtan a 1:350 would constitute a visit by the men in white

Tutorial time---------
I trust you all has a quiet and peaceful day . Ok the answer is more like � it could have been better!!! Any way now to some of the old fashioned how to or to put it another way .How did he do that!

Today we�ll progress to the assembly of centre section and just to refresh as this pictures shows each of the parts are given the letters A,B, and C for ease of reference..
.
First off the tapered side support arms are fitted to the side of part A { the tracking radar support} there is a slight overhang of about 1.5mm at the bottom and these arm will seat onto a circular base .


Here the circular base is formed from styrene tube 21mm od ,caped and tapered slightly inwards to the base on either side.


Work thus far . Note in the centre of the picture is part A . In front of that is a strip of litho for forming the access panel which will fit on to the top of part A . This section will then fit into the centre support as the arrow indicates. To the left and right of the picture are Parts B & C the arrow indicates that the adjacent parts are associated with and fit onto these parts.


Part A can now be placed in position { for the first time I just hope it fits} with the front flush with the front of the centre support.





Part B can now be fitted to part A .here to top is slightly lower when set against part A




Work thus far The arrows indicate as to where each part fits . It does get more clear as we progress . Whist the model here is 1:72nd the method can be applied regardless of scale .

I hope you can join me tomorrow for more of this brief tutorial on the Kashtan

Dave I have looked at this forum for a long time only as a guest as I'm on two forums already and did not want to join another as this can take time away from building but I have wanted to say to a lot of builders on this forum that their is an outstanding amount of talented modellers on here! But looking at your work in model boats as well as on here is outstanding to say the least. I love the length and detail that you go to to archive you subject and your meathod of breaking it down into workable pieces that makes the almost unthinkable piece not that impossable at all. An absolute great bit of modelling, thanks for sharing. Scott

[Dave Wooley]

Hi Scott Good to see you looking in and thanks for the kind comments .Now that there are builds going ahead for the Kirov, Kuznetsov and the Steregushchiy a build sequence for the Kashtan may help as it is not what you would call a straight forwards fitting. At 1:144 you could omit some smaller features without sacrificing to much detail. Not so at 1:72nd .
