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

[Iterum]

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.

 

[Ab Hoving]

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 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.

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.

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.

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.

 

[Rodolphe]

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

Hello Iterum,
Here is the promised list of the 16 ships built by the Admiralty of Amsterdam for the two programs of 24 ships. There is a printing error in the list: 'Maesdorp' should read 'Waesdorp'.



For the colour reference I include a picture of Nooms of Spiegel built by the Admiralty of Amsterdam in 1662, a picture of Van de Velde of Commeetstar of 1665, and a picture of Van de Velde of Gouden Leeuw built by the Admiralty of Amsterdam in 1666.





What do you think the right colour is?
R.

 

[Rodolphe]

Nice Rodolphe,
May I ask where you found this text?

Hello Ab Hoving,
I just noticed I missed your question. I found the contract for the ships of 140 feet of 1665 in the National Archives in The Hague, the Netherlands. The contract for the ships of 150 feet of 1665 can be found there as well.
R.

 

[Ab Hoving]

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.

 

[Rodolphe]

Hello Iterum,
The Boijmans Van Beuningen museum in Rotterdam has a drawing of Akerboom by Van de Velde which might by helpful for your project. Here it is.

And a detail.

R.

 

[Rodolphe]

Thank you. In Witsen's book you can find contracts for a 140 feet warship from 1664, ...
All nice stuff for study.

As to the color of the upper works: ...

Hello Ab Hoving,
Yes, these contracts in Witsen's book sure are 'nice stuff for study'. They for example give important information about the shape of the main frames of these warships. Information that is lacking in the contract of the 140'x37'x13,5' warship you posted here, and in the contract of the 140'x37'x14,5' warship of 1665 I posted here. Witsen's contracts show how flat the main frames of the Dutch warships of this period were.
Witsen's contract for the 140'x34'x15' warship of 1664 for example mentions a lift of only 8 inches over a width of 22 feet.
May I ask how you decided on the shade of green you used for the upper works of your Akerboom?
R.

 

[Ab Hoving]

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.
