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


Here is the work thus far . All most all of the primary parts are prepared all that remains before the detailed work begins is the two baskets fitted beneath each gun mounting.


The shape of the baskets on the Kashtan as fitted to Steregushchiy appear to be different from those on the Kirov�s and possibly other warships fitted with this type of CIWS.


There was a slight problem is identifying how the baskets[ in the absence of their correct name I chose the word basket to simplify things] worked and more importantly their exact purpose. My guess is that their job was to catch spend cases ?
The first task was to identify the parts . Looking at the baskets from various angles I noticed that the side slopes inward from about the middle whilst there is a definite curve to the rear whilst sloping upwards . Also at the front and the sides there are a series of perforations . next task was to draw up the shape consisting of just 2 basic parts , the base the side.

Before the base and side are joined the position of the ribs on the side which run fore and aft up and down was determined, more on that later. Also using the pictures I tried to locate each and every perforation in the sides.


The front of the basket also consisted of 3 sections also perforated. These where measured, holes drilled and cut to size .



These 3 sections are fitted into place


This was followed by an internal section also perforated set to the width of the front.


Using 1mm strip each of the ribs are fitted.


Fitting the ribs is a lengthy process and does require perseverance


Once again due to lack of pictures showing the inside of the basket I opted for modellers licence .


The next job was to find a method to secure the basket to the each drum . I have a confession I scratched my head and tried 3 different methods until I examined the picture more closely and it looked as if the basket was held in place by a tubular frame attached to the drum? I concluded that an L bracket attached to the underside of the drum and then into the inboard of the basket. Correct or not problem solved?


The two baskets in place


Progress thus far




The basic parts are now completed now the detailing can begin starting with the barrel supports but that�s for next time .

Hello Dave
the piece is incredible -
as i like to do preventing holes and insertion of other part of the components of the final piece. that takes a certain time, but guarantees a pretty piece and well performed. perfect

Dave, That is some very nice work, like the construction,

Hi Norberto thanks for looking in , there is still plenty of detail to be added and thanks for you encouragement much appreciated.

Hi Ron really good to hear from you and as always thanks for looking in . just finalizing the pictures , seems to take as long doing that as making the part.
Dave Wooley

Hello Dave,

Just love watching your work. That mount is truely amazing.

Keep posting as I am learning from every one.

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

Ok it�s time to move on to preparing and making the supports for the barrels
Once again I�ve tried to simplify the process by highlighting the items that are the focus of this part of the build. Each part is identified by a letter AB and C


Here marked A is the extended support that will be attached to the barrel . the width will correspond with the inside measurement at the �top� of the gun mounting .That�s the distance between the 2 L shaped rails.
The inner rectangle is marked for removal .


The next job is to mark , drill and cut B the bracket that is attached to the barrel . There is a �Flat� on the upper edge onto which will rest A .


Parts A and B prepared . note there are both left and right handed brackets


The parts prepared. Part C is slightly tapered also there is a overhang strip that will be attached to the �top� outer edge of the tapered section of C.


Using a small strip of masking tape, sticky side up to hold in place the support flat whilst the wedge shaped sides are carefully added .


When set the overhand strip od very fine styrene rod is added to the top edge.


The overhang strip of C is slightly reduced in size at the bracket end.


The next job is to fit the bracket around the barrel making sure that the �wide part is to the outside


With the bracket �B� fitted support A and also be fitted onto the top edge .


The new combination of Barrel and support can be temporarily fitted to the mounting . Once in place there are two short strips fitted to meet the back edge of the support .



The same method is applied to the second barrel support .


With the barrel supports prepared both can be added to the drums .That�s one less task.


Next time making and fitting the detail to the rear of the assembly . radar dishes will be the last job on the list.

Hi Dave
Bismarck have very small pieces to do too. sometimes a task time consuming.
but is very good when some difficult level piece is finished.
your air defence gun system is each time more beautifull
thanks for share

looking very sharp Dave
nice methodoligy in the way you have constructed the gun.

Hi Norberto I have made mention many times that small scales [ for example 1:200 -1:144 ] are difficult to work with and require added dexterity but much of the really fine detail is invisible, that helps .Up the scale and it it easier to begin with but the problem is, more of that invisible detail becomes exposed . Thanks for looking in .

Hi Roy good to hear from you , I must admit it's not an easy build but most certainly an enjoyable one.
Thanks for looking in .

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


OK we can now move on to the detail work , this involves electrical inspection boxes, drive motors, pumps and a host of fittings that I can only guess as to what their function is. They are visible to a degree which makes them within bounds of reproducing these to a reasonable degree, at least at 1:72nd scale .


As I mentioned at the very beginning of this brief build much of what you see in this part of the build is only available in pictures so some preliminary sketches where made as to what each item would look like if reproduced to fit the model . All I can say is what you see in its preliminary stage should not be seen as in any way as accurate , only representative.

All of the items seen in this picture relate to 1and 5 in the full size Kashtan
More will be said as we move into the assembly stage for now It�s all preparation.


These parts which will form the various inspection boxes with in the recess as shown in 4.


The same also applies in this the support for the tracking radar and illustrated as section 2


Last but not least a look at the parts that will fit to the front on the optical tracker these include the lens covers which are akin to small covers that protect the lenses when not in use .

Next time installing all the fittings and some references to the materials used.

Truly amazing Dave, excellent work. The next question is of course, when do you begin to make these to order........

Andrew

Hi Andrew Thanks for your kind comments . it was hoped that breaking down the build would making any follow on construction less problematic allowing others to have a go , this was the prime motivation behind the Kashtan build I really hoped I have achieved that result ? OK as for an all resin -PE alternative there could be one made at 1:72nd scale . Not by myself although I can prepare the patterns . More on this later. thanks for looking in .

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

Moving directly on to the assembly of parts for the optical tracker . These involve the covers for the optics and the associated hinges to the covering flaps .


Now the assembly of the fittings , electrical inspection boxes into the recess on to the area marked 4 on the picture of the kashtan . These are fixed into place .


This fitting is then temporarily fitted next to the radar tracking assembly marked 2


Assembly of the main fittings to the rear of the Kashtan can commence . First is the centre support for the shaft . Once this is fitted the two end supports are slid over the shaft and the entire arrangement can be fix into place .


With the shaft fitted all the remaining fittings can follow including the drive motor


Electrical feed boxes


Placed at either end of the drums are small servicing and maintenance platforms.
These are formed like parts of the baskets using .50 styrene sheet .




The two platforms are now in place


Progress thus far . As a matter of interest all of the parts seen here will be painted separately then assembled and fixed together . The barrels will be the last part of this build to be fitted .

Much of the small detail has now been added .




Change of tinlet to give an impression of relative size

Next task to construct the two tracking radar dishes .

when painted and weathered a photo shop treated pic will look like the real thing.

I have been following this thread trying to work out how it could be cast in resin and have found it to be a very interesting mental problem to solve. Just completed the master for HMS Leeds castle and taken the first test cast from the mould, Keep up the tutorial as i don't know how much longer i'll be able to do 1/700 and i have an urge to play with my models as well as build them, the C in C will be pleased

Dave i have two or three cans of this paint.
i never used. question: do you need prepare with a primer before paint the piece or you use the tint directly from the little can.
the pieces are superb as always
