AKERBOOM 1681 after Ab Hoving nominally 1/66 but drawings in 1/64

Hello my dear friends, I have got a question after looking in my downloaded files. And I would like to do this before putting my foot into something unpleasent:

These bars below the deck - what are they for? I do think keeping the deck's card in a curve, isn't it?

So are they just bent card board strips or are they curved cut cardboard (with the arc on the top)?

Thanks a lot.
 
I reinforced the camber of the deck by glueing one or more 3 mm thick 'deck-beams' underneath. So the beam was cut from 3 mm card and it secured the camber of the deck.
The deck existed of 1 mm card with on top a layer of white 160 gr paper. If glued together with the chosen curve it almost stays that way itself without beams.

Thanks Ab and Christian, I had thoughts in my head telling* me about laminating my own "ply-cardboad" by pileing layers a top each other - as you both suggested. And so the thinner material will be much cheaper to purchace, too.

On your hull, Ab, everything looks very light and easy to be build - what is your trick!?

Thanks for the hint!

It seems to me that the beauty of Ab's process is that it's light, and because so, it is quick. There is a lot of surface area for glue joints - even in a light construction - that provide tremendous structural rigidity, at the stage of applying the underlying cardboard "skin" to the bulkheads. Or so it appears to me. I have no experience, here.

In all honesty: the truth about my process is that I stole it all together from our East-European friends. If you really want to spledid methods, that's where you have to look. :)
 
Hello my dear friends,

today I was able to arrange a bit of progress with the centerboard:

I added the points -below and right the 12000 and left Hand above the VI number - for the slots of the moulds by using a pair of scratch compasses to get precise marks (in dark green) for cutting:

By the way I started to pick up the first real measurements from the transom for the construction of the prefabricated parts to be fixed there onto the hull:

That's all for today from the card yard.

Hello Iterum,
Just found your very interesting thread. It maybe is too late to be helpful, but I have copies of a contract for a ship of 140 feet from the Admiralty of Amsterdam of 1665. This is the contract used for building the second program of 24 ships. As you know Akerboom was part of the first program of 24 ships. Here are the first lines of that contract of 1665:

If you want a transcript of the full contract, I can post it here. Just let me know.

That would be very very helpfull, Rodolphe! In particular when we do get the list of the 24 ships' names, too. So this will make it possible to search for fitting WvdV drawings with the good intention to build realistic Dutch ships of the 80-years war :-)

Wounderfull handwriting by the way.

Thanks Marc for your point - I will Go slowly step by step. By doing so it will become bad enough so I do hope the "rescue" my AKERBOOM model by scratching the plastic layer into grain/texture and the colouring of it into something more "woody"...

We'll see.

Hello Iterum,
Glad you still consider the contract of 1665 has a value for your project. Here is the transcript.
(...)

If you need help with the translation of this contract, just ask.
I wil get back to you with the list of the eight ships built by the Admiralty of Amsterdam for the first program of 24 ships, and the list of the eight ships built by the Admiralty of Amsterdam for the second program of 24 ships.
I am sure you mean the ships of the second English war instead of the ships of the eighty years war.

Thanks a lot, Rodolphe, is there a list of the names of these 24 ships? For example her?

...or should we think about all the 56-64 gun ships by the Amsterdam Admirality distinguished by the number of gun ports?

A question a side:

Here the D7P (model for the rebuild in 11duimen = 1voet) with a blue painting....

...here the AKERBOOM's green used by Ab.

What colour reference is right - or both?

Thanks a lot.

Thank you. In Witsen's book you can find contracts for a 140 feet warship from 1664, another one for 'de Vrede' (1669) of 160 feet and a third one for a 170 feet long three decker (1667). For a 150 feet long ship he gives a 'shopping list' with the required wooden parts.
All nice stuff for study.

As to the color of the upper works: I'm far from an expert in this matter, suffering from a light color blindness, But the recipe I use is: take some blue paint (for instance Humbrol 109), add a little bit of black and a touch of yellow. Using paintings as a source may be a bit tricky, as some colors the painter used can have undergone changes as a result of chemical influences in mixed paint.
Just my 2 cents.
 
Your observation of the flat shape of the bottoms of Dutch warships up to at least the 70s is accurate. Something must have changed the design in the last decades of the century or the first ones of the next, because all the drawings that gradually begin to appear in these years show much more V-shaped ships. I guess it must have something to do with speed. But who am I?

As to the colors of my Akerboomr: as I said I am hardly an expert on colors, but this 'recipe' came from my Artitec friend Herbert Tomesen. I trust his sense of color better than mine. If he says green was not really used for the upper works, I simply believe him. :)

That is an extraordinary model, Rodolphe! Is the model contemporary to the 17th C, or by a modern builder? The carved work is so fine.

It is a contemporary model. Earlier our member olympic1911 posted some pictures of this interesting model in his building log of the Hohenzollernmodell.

Yes, there has been some progress in the past weeks. I've been meaning to post an update for a while now. I am currently in England enjoying a weeks holiday with my family. Will be back on Friday and will be happy to update the thread after my return. Ok - good to hear So we wish a beautiful...
