Thanks for the encouragement! Any project start with drawings. I found some sketches on the Internet in addition to the photo of the drawing in the museum. Then I made lots of photos of the boat itself in the Museum in Luzern. Based on that I have made basic drawings and rib plans on old fashioned millimeter paper (unbelievably still for sale!) Does that last picture say "Vancouver"? Yes after some years of tourist dives in the Lake of Geneva, the boat was sold, refitted for oil exploration type duties in the Caribean, and ultimately found somewhere in North America and brought back to Switserland. The basics of the build will be similar to HR Ms O-1, I.e. a plank on frame design, fitted with a bayonet ring to pull out the tech rack on which all electronics, pumps, motors and servos will be mounted. New for me will be the inclusion of lights, each window had a floodlight mounted in the saddle tank, then there were internal lights of course, and even the prop is illuminated by its own light - should be pretty in an evening event, but also LOTS of possibilities for leaks and shorts where wires go though the pressure hull. Below some of the sketches made from above materials! While doing this you also start to think of the sequence of the build, what to do first? What will be the most challenging (I think making the 40 windows in a way that they are clear AND leakproof! As well as the lights)? Also the rudder is integrated in the "jet-shroud" witted around the prop. I.e. Where the prop is fixed, it's shroud turns around the prop. And the pictures suggest the prop fits VERY snug inside the shroud...... I've made kind of a checklist of build items that I can continue to refine re-sort and add to.

A few months ago I started on my new project, it will be my third radio controlled submarine. "Auguste Piccard" was built in 1963 by the famous inventor family of the same name, who also built the bathyscaphe "Trieste 2", which reached the deepest point on earth. Auguste Piccard was a electrically powered submarine able to carry 40 passengers to the bottom of Lake Geneva, where the World Fair was held in 1964. The boat is reported to have made over a 1000 dives, transported over 33000 passengers and was recently completely restored and is now displayed in the "Verkehrshaus" in Luzern. A 30 meter long submarine in a landlocked country! I took a lot of pictures of the sub in that museum during two visits (one before and one after the restoration). I was lucky to also be able to make some photos of a book on display with a schematic drawing. I've not found any real drawings, though there is an actual model sailing around in Germany - I'm not the first to build her. The model will be 1:25, making the model 1.10 meter and 10 kg. Here are some pictures. Freek

Thanks for the compliments! The torpedoes have an elastic band, made out of flight rubber and oiled somewhat. With that I can apply 300 windings before the elastic band breaks. The prop is only 9 mm diameter and has a cm or so pitch - theoretically I could get 3 meter-ish, but as the Torpedo starts to counter rotate and has slip I'm getting between 1 and 2 meters or so. Amazingly the speed is very high and I calculate that the prop reaches 18000 rpm or so. Piet, your father was serving on some of the most modern subs of his time! But those deck tubes were rarely used! Freek

OK, this is my other boat, hr ms K-XVIII, or the predecessor to Piets O-19. I finally had an opportunity to test the torpedoes. These are rubber motor driven - have a great speed but not much range! But it looked great!

Ter lering ende vermaak! http://www.dutchfleet.net/showthread.php/16630-Proefvaart-en-overdracht-Hr-Ms-O-19?p=108753&viewfull=1#post108753 Fantastic how your boat looks. Freek
-
Piet, Your O-19 is really beautiful! Fantastic detail! I'm sure you've considered mounting the boat on the kind of blocks that she would rest on in a drydock. I've seen several models mounted this way and it adds nicely to the real circumstance. Of course, then you'd have to explain why a perfectly looking boat would enter Drydock...... Alternatively, how good are you building a reef? Freek

The model is 28 cm (or 11-odd inches) long. It's a 1:350 scale model of a adapted British destroyer design built in the Netherlands in 1929 to 1931. Modern in its time, they were completely outclassed by 1942. As to knowledge of this naval event in history, the battle of the Java Sea (in which two of the eight of these took part) was the largest surfac gun engagement since the battle of Jutland - not that is impressive. 10 allied (American, British, Australian and Dutch) cruisers and destroyers were lost trying to interdict the main invasion fleet heading to Java, mainly by the superiority of Japanese gun calipers, their superb long lance torpedoes, and their almost total air superiority. It was a very tragic battle lost in the 1930s military budgets, costing over 2100 lives and delaying the invasion of Java by exactly 1 day. Other destroyers of this class faced even more insurmountable odds, one was the escorting a merchant ship and became the sole focus of hours of air attacks from a Japanese fleet carrier, and another faced German Stuka divebombers trying to displace German paratroopers in Rotterdam. I think very few Dutch people know this part of history, except for the famous last words of Admiral Karel Doorman Leading the Allied ships into the Battle of the Java Sea: " ik val aan, volg mij". (I attack, all ships follow me). Our newest, largest ever and soon to be commissioned Navy ship was named after him. Freek

the model is finished. I've decided on the name Hr Ms Banckert. this destroyer was in dry dock in Soerabaya when the Japanese invaded Java, and was sunk (including drydock) by my other model Hr Ms K-XVIII (herself then destroyed by her crew). All 8 of the class were sunk in WW2, one by the Germans in Rotterdam and the others by the Japanese in the Dutch East Indies. The first time working with PE and with airbrush has not been a disappointment. With a lot of patience it was well doable and the overall level of detail that Boris built into this model is very nice. pacific Crossroads has a set of models of many other Dutch warships that fought in the pacific, and I can certainly recommend then to anyone interested. freek

The Admiralen class destroyers were a series of eight destroyers built between 1928 and 1931 for the Dutch Navy. All were lost in WW2, one in Rotterdam and seven in the Dutch East Indies. The kit is from Pacific Crossroads, designed by Boris Mulenko, who is Russian and has built models of many of the Dutch ships that fought in the Pacific. The kit is a mix of resin parts and PE, and I have never used either. Here are some of my pictures of the start of the project Started with my (also new) airbrush. I practiced a bit on a small helo project (still visible!) but now started using it in earnest. Waterline is nice and straight and painting the PE before use seems to work. I put the resin parts onto double sided tape. The hull after painting on the box from Boris. First experience with PE - I bought one of those bending tools and read a bit on Internet. Main tool seems to be patience and it's still holiday... The nearly completed bridge, I count only 7 errors (all of them thinking errors - wrong parts on wrong places etc) ! And a start on the 75 mm gun platform between the funnels. All for now - so far I like the work and I very impressed with the extreme detail in the kit. freek

Hi all November 23rd, 12 degrees C outside and sunny! Today I went back to the cologne rowing club waters, my sub was followed under water by an ROV taking pictures. I must say, model subs look fabulous in their own element! Still some work planned, I want to replace the wires to the mast (they stretch too much), install turnbuckles, decals, and a few other things Freek

Hello all, Slowly this thread is turning into a sailing rather than a building log! Last weekends trip to a nice clear lake in Cologne, home of the oldest German model sub club. Note slight damage due to underwater collision Also note the even older sub encountered in the last few seconds... Freek

After the "shakedown cruise", as Piet called it, some more details were added to the boat. I redid the waterline, though still not as good as I want it. Added supports for the deck, a forward guide bar for the anchor chain, cables on the mast and a flag in top. Also copied one of Piets additions, the "pikhaak". Which was stored under the deck. A flag was used by these boats on exercises so the "enemy" Could keep track of the subs movement and prevent collisions. In the 1909 and 1910 Dutch Navy exercises the boat sank the armoured cruisers of the surface fleet! the boat has now hads its second voyage, in de Vinkeveense plassen, nice and clear water in the centre of holland where this picture was taken. Again unfortunately the photographer did not capture the dozens of other models of Dutch Navy ships that were sailing around!

Piet, see here how Paul Burghorn has made the plans for his sloep http://www.modelbouwforum.nl/forums/bouwverslagen-schepen/139613-mijnenlegger-hr-ms-nautilus-1930-1941-a-13.html Freek

Boris there is nice model of the O-1 and two of KXVIII in Den Helder. I agree Piets model competes well with them, but musea are not that keen on static model displays anymore, nowadays it has to have buttons, a screen and a theme! Freek

Thanks for your kind words! Yes I was very pleased with the boat and it's performance. The trim was perfect and the boat as stable as a rock! Manoeuvrability also much better than expected, hull shape seems to make for a stable and fast boat. Mark, good question on control. The key is a long wavelength transmitter, so the signal will penetrate water. My very old 40 MHz transmitter can penetrate clean water to maybe 5 meters. In US I believe 75 MHz is used. Most model plane people have moved to 2.4 GHz, which is a better frequency for high dat rate transmission, but being microwave won't penetrate water at all. The antenna is inside the boat, under the wooden deck and I guess the wavelength that penetrates water does the same with water and plastic. Freek

Well friends, The maiden voyage of Hr ms O-1 went extremely well. The boat was pretty much perfectly trimmed in my bath and todaz was tested in the swimming pool in Zutendaal - beautifully clear water! I had a camera on a tripod under water, and one outside of the pool, and together these captured below 7 minute summary of a day worth of sailing. Yes there were some other boats, but somehow I never saw those - and they 'surprisingly did not show up in pictures'. figure that! I'm certainly happy with the boats performance, now I can get back to redoing the paint job and look for more details to include! Freek (could not find how to embed a video!)

I thing THE stanchoins and antennes and some maats are taken down pro to diving, at least in case of K-XVIII thats described in books written by THE XO Freek

Hello all, I hereby cordially invite you the maiden voyage of hr ms O-1, to take place in a swimming pool in Zutendaal, Belgium this coming Sunday! Over the past weeks I remade the divetank , so I now have a 300ml bag rather than the 120ml before. Spent significant time with the boat in the bath to balance it, and Im fairly happy with the result. Under water the boat seems to be level with the tank pumped full, and above the water, while it does not quite reach the painted waterline, the decks are nicely above the water. Subs always have 'variable' water lines anyway. The pressure sensor inside the boat switches the pump off when the bag is full, and then the boat just dives. Trimming it with the pump leads to below nice image of a sub 'hanging on the periscope', that's what we aim for! Freek

Given the wealth of targets on this forum, I loaded some more shot - now nearly 2 kg on board and total weight of the boat is 3.8 kg; exactly the nominal weight of the RL-boat divided by 32 to the power 3. Seems the hull shape is pretty good to drawing. By the way - I was given the drawing set of this 1905 boat by Fred Huygen, who unfortunately passed away a couple of weeks ago. He built many per-war Model Dutch submarines including Cornelis Drebbel , a beautifull oar powered sub from the 1760s and O-13 - still on patrol, for which he built the model for a TV documentary about her disappearance off the Danish coast in 1941. Both my subs were inspired by Fred's work. Yesterday was a large submarine meeting in Cologne, and we missed him. Back to the present. The pic below shows the wet testing of the boat to determine the volume of the dive-bag. The stern is lying in a container of water, and using the transmitter and some kitchen scales. I could determine the dive tank is only 120 ml. That's much less than the 300-400 I need to get the boat anywhere near the waterline when not submerged. I thus ordered some more of the tough plastic sheeting to try make a bigger one. The shot is pretty much distributed to have the boat level under water (keeping a reserve bag of 250 gram shot in place of the dive tank - which I can reduce if I manage to make a bigger one. As seen in my bath, the boat lies a bit deep and not perfectly level. It's pretty stable though. I took both my boats to the world famous submarine day in Cologne, unfortunately my K-XVIII refused to dive after a nice round on the surface - pump seems to have failed or developed a control glitch. And with so many large (5 foot or more), and FAST subs in the water I was not comfortable trying my small boat with its minute reserve buoyancy. Rather do some more bath work! However here were some of the visitors.

With 1.3 kg lead shot glued in the hull, so that the tech rack slides just overtop. With the lead the boat now weighs 3.2 kg (sorry, i don't calculate in pounds!), and based on the displacement I expect the total weight to become 3.8 kg, including 200 gram or so of water in the dive tank/bag. The boat has not been wet (as the paint is still wet) but next step is to carefully balance the boat with the remaining lead shot in a tank, and of course check for leaks. Exiting!

Starting mounting the deck covers, and the first set of planks on the deck. The rope is about 0.4 mm, so maybe. 1 cm in RL. the rope is tightened by a 12 mm long tightener, I bought 6 but looking at this picture I think it's a little too big for this scale. I may look for another solution for this. Any ideas how to keep this tight Unobtrusively? The hinges for the deck covers are still missing All for now Freek

Hey Piet, those are MUCH nicer torpedo tubes than the two black ones I built for my KXVIII, at the same scale. Really I'm very impressed! can I order a pair, working and able to fire my rubber band Torpedo's? Just kidding !! Yours is the best combination of a superb build, great link to history and personal story - I read it every day! Freek
