Multipurpose workboat "Viking Energy" 1/50
« on: May 01, 2020, 12:44:27 pm »

Hi there!

My Name is Ralf. I've build in the last seven Months the Floating Crane ENAK (1/50 too)
Fully functional and with the max sizes of 150cm length (59 in), 52 (21 in) cm width and up to 140 (55in) cm high, it is a little Monster on the Lake.
So I need a scale Recovery/Push Boat to get it back if it fails.

After some research in the www I fell in love with this little guy

http://www.landfall.nl/viking-energy

General Plans are available and many pics too.

BTW: I'm not a native english speaker, so please forgive me possible faults in my Posts.

And now the Project starts like others with planing and sketching with Fusion 360.
Hull and Frame including the main drive components are roughed up. Wood is ordered.

Welcome Pufferfish.

Firstly there is no need to apologise for your English. It is very good as is your punctuation.

Your choice of model is interesting and will hopefully make a really nice model. Remember that we are here to help if necessary but, whether you need help or not, we will be interested in your build.

Enak is a massive crane! I think that you are unusual as most modellers I know built the tug first and then looked for something to tow.

Hi,
thanks for the kind welcome.

-----Todays work was again just virtual planning. This boat has almost no freeboard. Together with the asymetrical position of the cabin I can't use the usual technique with a coaming under the cabin. After drawing all areas on deck with something on it, I've found a bigger area to get under deck. It will be flat and sealed like a model-submarine.

I love this asymetrical plan.  The front bumpers are really on this position  :-) And today I discover a special feature: Behind both rolls between the bumpers are retracable bollards for guiding the towcable.

Hey Ralf, I read your Crane posts and was going to ask what you were planning to build next but decided not to because some people like to have a breather before looking at their next project!


Obviously you have chosen and have already made a good start. Keep up the good work and welcome to the group of keen builders.


I love the Puffer Fish  :}

The 1500mm x 520mm x 1400mm dimensions are for the crane?

Viking Energy will, I think come out at 530mm x 220mm.

Indeed, that are the sizes for the crane.
And 53x22 is for the workboat.

Sorry for the missleading sentence.

Hi,

waiting for materials and props etc...So the build starts with the kort nozzles. A simple turning job and some threads.
Parting the rings


Drilling the threads on the by chance mounted roundtable.


Ready to use.  (They will be powder coated later ...)

Small things, later almost invisible, but important. The connectors between kort nozzles, rudder and skeg. More work to adjust the angles (3 to rudder, 11 to skeg) than to mill.

Anyway. They are done. (The screws will be sunk later, of course)

Nice simple engineering but still looking good. Do you send them off for powder coating?

Thanks.  No, I'm able to do powdering with little things at home.
I can't paint. I've tried it, but I can't get a really good surface finish.
So i've tried powder coating and it is my first choice to make a good surface finish on metal.

But:  It is really a mess. A dedicated room for dirty works and a own oven are a must. The rest is simple to learn.

 Three props?!?  That seems excessive! Why so much pulling power?

Of course. I'm owner of a resin printer wich is predestined for such small details.

Very interesting Ship! Thanks for the link.

Schilling rudders as well. 

Indeed. Thank you for the hint. I've planned to mill just simple squared rudders so far, my new plan is to print it with the correkt curves.

Such a ship looks so simple, but if you look deeper, you'll see details and details and details...

For you certainly boring, for me a very exciting work today.  Adjust the frames and glue the stringers. Despite the handbuild frames, all things fits reasonably good and at last, the important things, sides and deck, are straight and at right angle to another.  :-))

Thank you, Sir.
-----Good progress today. 2/3 of the hull is now closed. Last third will be done when I get the propeller-shafts.

I'm surprised that I'm able to handle wood so precisely. Milling balsa is extremly dusty, but works good and exact.
So, this is the actual state




The sharp edges





Proof of concept: My idea with the embedded Deck.



Looks good enough to try
