Hr Ms O-1 by FreekS - RADIO - first Dutch submarine 1906-1920, 1:32 - Finished


Recommended Posts

Hello all,

 

This is my first build log on the forum, and my third ship overall. The first was a Dutch Navy contemporary frigate Zr Ms de Zeven Provincien, and the second a world war 2 submarine, Hr Ms K-XVIII. Both are radio controlled and both hulls were made with the bread and butter method. That worked out very well for these larger vessels but now I intend to build a much smaller sub and will need to be much more economical with space.

 

So this will be my first hull built out of wood with planks on ribs.

 

Hr Ms O-1 was a Holland-class submarine built as a private venture by Wilton Feijenoord and sold to the Dutch Navy when it has passed some trials set as condition for her purchase. In subsequent exercises she proved very capable to defeat the then surface ships of the Dutch Navy. She patrolled the North Sea during WW1 (but thankfully the Netherlands remained neutral throughout that conflict).

The Holland boats have beautiful lines, and I was hooked when I saw a working model of an Austrian Holland class at a meeting in Lichtenstein some years back.

 

Please feel free to comment and advise as I have some experience, but little in this kind of hull building especially.

 

Groeten, Freek

Hi John,

 

I plan to install a bayonet closure roughly 1/3rd distance from the stern. All the technical pieces will then be mounted on a rack attached to the stern part and pulled out of the front. It will be tricky to mount the motor and propellor assembly and the pushrods used to operate the dive planes and rudder.

 

So the whole hull will be dry and waterproof. This is a fairly well known way to assure waterproofness (though I have not used it before). The main challenge will be to find space for all the technical stuff (receiver, speed controller, motor and servo motors, batteries, pump for dive tank (waterproof bag) and electronics to control it all).

 

But first the hull - next to the waterproof cigar I'm making now the boat has a flood able deck, a single torpedo tube and a conning "tower" with periscopes and masts.

Freek,

 

Nice to see another submarine construction log. I find them particularly fascinating.

 

You have made a lovely start. The construction thus far is reminiscent of model aircraft construction - though I have no doubt the similarities will soon end with further work. :)

 

I look forward to your next entries.

Hello Freek,

 

Fascinating project!  I'll draw up a chair and watch the build.

 

Cheers,

Thanks all for your kind words!

 

Yesterday I managed to stiffen the pressure hull by inserting wooden blocks in-between the frames. This will help the planking of the hull - without taking away from the room inside the boat. The boat seems straight and next step is for me to verify the accuracy of the frames with a plank, and to start drawing the complex bow and stern pieces - which will be the end-points for the planking.

Also late last night we performed the age old ceremony of fixing an old coin in the keel. We selected a 1 Dutch cent coin (no longer in use since the euro) from my birth-year and with the image of Queen Juliana on it. This tradition hopefully assures 'een behouden vaart' - safe travels over the high sees.

Thanks Anja!

 

On my birthday I made the bow and stern from wood left over from my frigate project. Using a band sander I got the pieces nicely in shape and even prepared the muzzle of the single 18 inch torpedo tube that the O-1 had. More time went into checking the frames and correcting small deviations. I started making the planks, from 3 x 8 x 600 mm wood. These were narrowed at both ends and after a few hrs soaking were clamped in place to bend them into the required shape.

 

I made about 5 of 30 planks so have to do a few more!

 

Note how small O-1 is vs K-XVIII !

Hoi Freek, she will look exactly like the original as seen from the shape of the hull.  btw, Queen Juliana is my most favorite person, said from personal experience.  That one cent piece should serve your O 1 well.

Love the pic of your K XVIII as well.

 

Cheers,

Piet, The Flying Dutchman.

I still owe Piet a video of the K-XVIII shooting a torpedo from the deck tubes.

 

Here's a mini video build log of the work I did to make the torpedoes operational - using rubber motors as the propulsion method.

 

 

Hope you will enjoy the 5 minute film - the sub shot is right at the end

Thank you very much Freek for the video!  I watched it several times and I'm impressed with your persistence to make it work.  I won't go that far with my build of the O 19 though, I may an eye in the process   ;)  ;)

Hallo all,

 

Thanks for the kind comments on my rubber motor Torpedo's!

 

Back to planking the hull.

 

I'm shaping each plank with a mini plane, but progress is slow. I learnt I need to ensure the plank is fully pre-bent before mounting on the hull. Six planks done and I think I have the hang of it now - though at cost of removing one after it had too much tension in bow section.

 

Certainly gives me a lot of respect from those of you creating much more complex hull shapes!

Freek,

 

The model is coming along very nicely.

 

I am trying to visualize the size of the model - the pencil gives me a clue. It would be great to have a rule alongside it in some of the photos to help.

 

Keep up the good work.

Ian,

 

The hull will be 68 cm long, and 11 cm in diameter. The original boat was only 20 meters long, and the model is 1:32.

 

At 125 tons displacement, the original was small, and the model will weight approximately 4 kg and have a dive tank, most likely a plastic bag, of about 500 ml

 

inside the model I will need to fit

- a motor with speed controller

- batteries and receiver

- pump for the dive tank (bag) with its controller

- two servo motors with pushrods controlling the planes and rudder

- quite a lot of lead to give stability and make up to 4 kg.

 

The boat will be very full!

 

 

Here's another picture of the original

Hallo all,

 

Planking is about 75% done, now I have to think about closing the gap and how to fix the last planks in place without using the small "vices" (klemmetjes).

Also in front of the boat the small plane I used to shape the planks and the Bajonet closure which just arrived from Norbert bruggen. Norbert is a legendary model sub builder in Germany and sells all sort of usefull parts.

 

However still lots of planking and sanding to be done!

Hoi Freek,

 

Looking nice, she's beginning to take shape now.  "Klemmetjes" would be clamps in English  ;)  It's great that I still understand Dutch  :)

If you are covering the hull with glass and epoxy anyhow why not use small brass nails instead of clamps?  I did the same with the O 19 but did remove the nails after the glue was dry - - - I think.

 

Cheers,

Piet, The Flying Dutchman.

Hello all,

 

Hull is closed! Last planks have been shaped and mounted and after a night drying I used the band sander to shape the planks fit with the bow and stern pieces. Lots of sanding comes next - probably first with a little electric sander then with regular sandpaper.

Glass"fabric" has been ordered with low viscosity epoxy resin to seal the outside with a protective layer. Will need to read up on how this is done !

 

After that comes the point when the hull needs to be sawed in two for attaching the bayonet. brrrr.

  • 2 weeks later...

I finished planking the hull and after a first layer of epoxy I added two more layers with woven glass fibre to make a strong hull.

 

Now I used epoxy putty to start evening out the irregularities in the hull. First time sanding after 18 hours gave a reasonable smooth hull though with some of the glass fibre weave still visible. So I just applied the second coat.

Meanwhile I also started on the superstructure. As the dive tank inside the hull will need a volume equal to displacing all the materials over the waterline, it is important to build the superstructure light.

 

I used 1.5 mm birch triplex for the frames and 0.8 mm for the hull plates above the waterline. This area needs to flood so I need to ensure the air can go out when the boat submerges.

 

See attached an outline of the long and narrow superstructure.71637CA7-22C2-4427-B9DF-20CD3CD6D6EB_zps

 

and below a detail on the drawing

Hi all,

 

Of course first days of the holiday I have to catch a flu! Poor weather here but at least it gave me some time to work.

 

The hull is now nice and smooth and I will add another layer of epoxy once I have enough of the superstructure to waterproof that as well.

 

I made some ribs for the deck section and more or less finalised the sail. Here are some overview pictures - the shape of the boat is taking shape!

The front part mounted on the bow is the torpedo tube door which pivoted open (in real life). But there will be so limited room and access in the boat that I decided against making this functional (and I'm no Piet!).

Hoi Freek,

 

That's beginning to look really impressive.  Now, if you had upped the scale by a factor of 3 you could have installed a real torpedo tube system that fires real torpedoes and with an explosive charge  ;)  ;)  

I'm kidding of course, no need to make everything workable.  It's already a great job you did with the K XVIII!!!

 

Cheers,

Piet, The Flying Dutchman.

Yes Piet!

 

And with automatisch reload, after all O-1 carried two reloads for her single 18 inch torpedo tube (and the torpedo's had to be brought on board in three pieces and assembled inside!)

Ive considered making a functional tube, but Then I'd never use KXVIII again! Also, considering how full my KXVIII is with electrical 'stuff', I know I'm going to struggle finding space inside O-1.

 

Thanks for the interest - as always, and merry Xmas
