Great work indeed! :thumbs_up_1:

I have been looking for tiny balls to use as 1/300 scale canon balls, and found this:
Image

They are tiny balls of solder. They look perfectly spherical, and while you can deform them by squizing very hard, they are certainly hard enough to withstand normal handling with tweezers.
Sizes range from 0,2 to 0,76mm with 0,05mm intervals (except 0,7mm as far as I can find though....). I guess 0,65 would be best for your use.

Another option are 'caviar beads', used for nail decoration:
Image
I didn't find them in 0,7mm size, only in in 0,4 - 0,6 and 0,8mm. But probably that will be close enough too.
The size sorting of some brands seems to be more precise than others. This one has a '0,6 - 0,8mm' range: https://www.magicnails.nl/caviar-beads- ... 08-mm.html

Thank you, guys, glad you like this further adventure of mine ;)
And thanks for your hints, Maurice and Marijn! It´s quite unbelievable what can be bought these days!

I admit I have not made use of your advices. I needed just one ball (I thought) and of course I wanted it NOW :heh:

So I´ve done some thinking about how can you get a really small ball in a household. I considered making one of solder myself, it happens quite often if you drop some liquid solder while soldering into rosin that it forms a nice round ball. But before I gave it a try I had another idea: a ballpoint pen! It took me only seconds before I found a dried ballpoint pen refill, squeezed the ball out of it with pliers, cleaned it with spirit - and lost it forever to the carpet monster :(

Another try, handling it much more carefully. It measured for 0.96mm, a tad too much. Quick check on the internet, 1mm is standard, finest breed is 0.5mm and - hooray - the fine one is 0.7! Quick check in my wife´s drawer revealed one (dry, of course ;) ). Handled it carefully, took a photo, got ready to attach it to the sub - and it was gone again!

The photo shows a comparison of 1mm and 0.7mm balls to a coin and a pin. The balls are really tiny...

The next try was successfull at last. I had to salivate the tweezers in order to hold the ball safely. Applying a dot of thick CA glue to the base and hold the model upside down until it cured. I think it looks just right :wave_1:

Another great project to follow. The solder balls are a great suggestion. They make good rivets for 1/12 scale cars, too. If you have any friends with shotguns, there are a variety of shot sizes for doves and other birds, snakes, etc. A sporting goods store might even have a comparison chart.

If you want to try to recover your ballpoint pen balls, sweep the floor into a small pile and run a magnet through the pile. Just use the magnet if you have to deal with carpet, or crevasses.

Wonderful, crisp work. I like your pen-ball solution.

So this is the current status as of now. It is still missing the small "ball" on the four-pod near the bow, I am still looking for a suitable part (0.7 mm diameter) to be used for it. Not sure what was the purpose of it, one of the BOGPs marked it as an "S.C. tube", others made suprisingly no mention of it.
Let´s see how it will all look like after airbrushing (after vacations ;) ).


I think this "ball" is the head of a JK passive sonar. Looking at Friedman's "U.S. Submarines Through 1945" (p142-7), I find "Many boats had JK high-frequency passive sonars placed atop their old SC-tubes forward, to form a combination low- and high-frequency passive set." The pictures and drawings seem to match, and he states that it had a "19-inch spherical cover", which works out to .7mm in 1/700. Thanks for poking me to look this up, so I figured I'd share.

Thanks Mike, good idea about using a magnet. In fact, they jumped somewhere on my crammed work table, not the floor. Anyway, I´ve got the one I needed, so I´m fine :)

Thank you for solving this little mystery for me, George! I cross-checked Friedman and there is a note about the JK sonar even under the S-44 drawing on page 145, mentioning it was probably installed during her late 1941 refit. I am not sure about this as I can see these balls on earlier photos, too.

Some further adjustments done.
Bulges above fwd planes, aft bollards and a deck winch fwd added.
I noticed the aft antenna mast was incorrect so I removed it and scratchbuilt a new one from brass.

Thanks for your kind words, Marijn!

Actually yes, I airbrushed the sub already, but I had some terrible problems with my airbrush this time, so I haven´t even tried much for some paint modulation etc. as I originally planned. Either I give it another try or I sort it out in the filters phase.

I am also not particularly happy about the fit on the bow. I amended the PE after my first trial earlier this year aiming for a better fit and that worked quite fine on most places but the bow is still not good. The precise and accurate one inside me contemplated about trying to sculpt what´s missing there while the other me, the lazy one, argues about concealing it with a bow wave like on the USS Torsk photo below. I just doubt an S-class sub would ever make such speed while patrolling in enemy waters, waiting for her prey... I don´t want to make the sea too rough as I recall no mentions about bad weather off Kavieng on August 10, 1942.

Great work Vladi :thumbs_up_1:

Perhaps a way to make a realistic bow wave and add some dimension would be to model her as she is just beginning to dive and go in for the kill?

I decided to be quite radical in not giving up the fit on the forward quarter of the sub. I used an extremely thin piece of plastic that started it´s life as a separator in a pack of prosciutto, it fitted just under the PE thus visually correcting the shape. Some sanding and liquid putty made it for a smooth transition, I am much happier about it now.

Now leaving the paint to cure before gloss varnish and some weathering.

Some weathering today :cool_1:

Used my usual method of filters, pin washes and slight dry brushing, all of it using artistic oil paints - very cheap and very effective method I learned from the Ship Models from Kits book by David Griffith.

Agreed. Nice rework on the bow. I certainly understand that compulsion.

Thank you!

Now here comes a question: should matt varnish be used as the final seal on a submarine at sea? My conclusion by now is negative – a surfaced sub would remain wet most of the time because of the spray and its very low profile above the waves. So may another thin layer of Klear / Future (Pronto in Europe) - which tends to cure as a satin finish - be a good solution for most of the hull and bridge? Plus some more gloss areas on the bow etc.?

And another question: would a surfaced sub on a combat patrol fly the national flag?

Now to making the seabase

I wanted to try another approach this time using Styrex XPS. On the other hand I was not looking for a drastic change in style of seabases within my Savo Island collection by using a thicker Styrex layer and creating larger swells, so I decided to stay with the 4mm plexiglas as a basis (it serves also as a weight!). I added only a 3mm thin layer of Styrex on top of it. That allowed for some light swells that I used to make by putty or paper in the past - definitely easier and faster with Styrex.

As usual I prepared the wave pattern according to the excellent http://www.steelnavy.com/WavePatterns.htm guide by Donald C. Simon - only to realize that such pattern is not relevant for a small and slim vessel like a submarine. So I searched for some photos of submarines at a moderate speed that could be used as a guide, the one of USS Torsk posted above being a good example. It turned out not the best idea to mark the wake with white marker, it later tended to show through the blue paint so another layer was required

Another material I tried for the first time was the Green Putty I used to sculpt bow waves and wake, it worked just fine.

Then I used a car paint spray can for the base dark blue and I was quite surprised to notice some of the Styrex being “consumed” by the paint although the can said the contents was acrylic paint! It can still be used but the first layer should be really thin to prevent irreparable damage to the Styrex layer.

I´ve never fixed my models permanently to the seabase before. The narrow gap between the hull and the seabase (covered with acrylic gel medium in the meantime) is usually noticeable only from overhead and I preferred the (yet theoretical) possibility of removing the model and using another seabase for it. However, in case of a submarine there was no other way as the convex hull would make the gap too obvious. I used the light wall putty to fill the gap. Being water-soluble it is easy to remove any unwanted marks on the hull. It is also white colour so there is no need to paint it in the vicinity of the hull as it looks like a good representation of foamy seawater. Cotton wool and acrylic gel will make it for the bow wave. I also tried one new material – AK Snow Sprinkles for the lighter foam. The Snow Spinkles are essentially tiny transparent balls in acrylic gel medium. This gives a quite unexpected effect of making the bow wave less even and smooth, adding “droplets” to it.

I am sorry but I completely forgot to take photos of final phases of the seabase construction, I was perhaps overexcited that the work comes to an end :(. You´ll have to wait until I take photos of the completed build – coming soon! Sorry for the waiting time but I want to show it all at the time of the 79th anniversary of the Savo Island events in 10 days time ;)

Calling it done – please meet the S-44 just in time for the 79th anniversary of the Battle of Savo Island!

Image

Unaware about the Savo Island events the previous night, the S-44 sighted the formation of four enemy heavy cruisers at 0750 on August 10th, 1942; their track less than 900 yards away. At 0806, she fired four torpedoes at the rear ship, only 700 yards away. By 0808, three torpedoes had hit; the Kako was sinking; and S-44 had begun her escape (adapted from DANFS). Kako sunk in 5 minutes. The remaining cruisers of Cruiser Division 6 rescued Captain Takahashi and most of Kako's crew, but 34 crewmen were killed.

Launched in 1923, the S-44 was considered second class by the U.S.Navy by 1942. She was on her 3rd war patrol from Brisbane, was partially damaged by heavy swells by the end of July and then deployed off New Ireland in the Kavieng area. The old Mk 10 torpedoes she used had old contact exploders and these worked just as intended, unlike torpedoes of more modern US submarines at that time.


Image

My model shows the S-44 patrolling on the surface just before sighting the enemy force and diving for the kill, the only „win“ of the Allies accounted to the Battle of Savo Island.

Image

This “fast & simple” detour build took me half a year to complete – well, ok, it happenned in parallel to working on other more complex projects. Researching the sub and designing two versions of the PE took definitely much more effort than the actual build.

I think came out well compared to the original resin model, but mastering 3D design & print would definitely be the better option for similar projects in the future.

BTW I´ve got 3 spare copies of the final PE, send me a P.M. if interested - but I am afraid postage would be more expensive than this rather small PE sheet ;). Tom´s Modelworks hull and gun are still needed to complete the model.

Very nice! I like the pic with her victim.

PS: I'll move this to the completed models forum.
