Mike,

 

Just finished reading your build log to date and wow, what a project! You've obviously done this sort of thing before, your work so far is absolutely stunning. I particularly like your method for producing the ballast - I know lead is horrible to cut and/or machine, although apparently putting it in the freezer overnight between the various shaping stages does make it easier to work!! (It's not something I've tried but know of plenty of modellers who do & say how much easier it is).

 

I'm really looking forward to seeing how you deal with the planking, as a future project for me will be a 1:10 scale model of my father's yacht, a Saga 40, which has similar lines to 'Stavanger'.

 

Regards,

Hi there

 

@John

Thank you for visiting my workshop - yes, it's probably what you're saying!  :)  ... and I'm sorry, called you incorrectly Jim, at my last reply - checked only the avatar's name.

 

@Dimitris, @Michael, @Omega1234, @Nils, @Bob

All of these great comments and many likes - thanks a lot!  :) Nils, the keel is about 5kg.

 

@Row

Thanks for visiting and your great feedback!

 

So, what can I say? ... however, it is really my first scratch build! Of course, I have very often built various types of models as I was a boy – but it was now about 35 years ago. At that time I have built especially R/C race cars and aircraft, but all without scale claim.

 

By profession due to I have much to do with design methods and manufacturing processes and I was working by an architecture model maker for earn some money while studying. Currently, from time to time in my professional life I build architectural working models in card. So, these are my previous points of contact with modeling.

 

... Yes, I have read from the method with the freezer - and yes, we need once to check that.

 

I would be pleased about your project of the saga 40 and I will follow it certainly.  :)  Oh yes, the similarity to ’Stavanger’ is obvious - a contemporary adaptation and a beautiful boat!

 

Regards

Mike

Ahoy!

 

As you all have taken note, that in the last workshop-log, keel, stem and sternpost were already assembled to a unit. Therefore, I will make a short rewind on the appropriate step (see below).

 

Later, by doing the last dry try, I remarked on some frames a difference between ’is’ and ’should’. On the appropriate parts, corrections have to be done – so this is the content of the following shown step.

 

How this difference? During I checked the problem, I've noticed that the various old plans does not always correspond with each other. Further it happend often a insufficient resolution of the scans what are one part of my planning basics. The other part consists of numeric data, this way I was able to interpolate and doing some corrections.

 

The next step shows the definitive Assembly of the structure. What we can already guess and on this I am looking forward as a little boy on Christmas, is the wonderful hyperbolic shape (saddle surface) of the deck! :rolleyes:  

 

Regards

Mike

Hi Mike,

 

I concur 100% with Patrick's words - as the various components come together it really does give one a better idea of Stavanger's lovely shape.

 

Looking at the last picture of your post and bearing in mind the sectional size of the midship frames, I wonder if it may be beneficial to insert some temporary diagonal cross bracing pieces to ensure the frames don't flex when you come to fit any stringers and subsequently plank the hull.  Food for thought if nothing else...

Hello Patrick, hello Row

 

Thank you all of you both for visiting - I like to pass the compliments to Colin ...  ;) 

 

Row, I was also thinking about braces but I'm currently working on the plank hallway No. 9 (counted from the deck) and the hull gets stiffer with each course - the bracing will not be necessary.

Hello everyone

 

I must confess, I don't actually have experience in sheering/streamlining and planking, I do it all for the first time. So, please you'd forgive me, when all awkward therefore comes. The below described approach to this theme arose from a mixture of laziness (to create a full CAD-3D model), intution and analysis and especially on my lack of any other method. There is certainly a danger that all this is already known, and I am the last of all - then let me know.

 

(Sheering/streamlining: I don't know the correct term in English, in German it is called “straken“. So, maybe someone can help me ... ).

 

As I have mentioned this already above, I intend to plank the hull in original geometry. At the beginning I asked me the question, whether such efforts probably justifies, if later everything will be painted.

 

Finally I persuaded myself to look at this whole procedure as an exercise - an exercise as regards a future project where I would need a visible course of planking. By the way, there is a other goal I try to reach, it is the attempt to grind not the whole hull round. Instead, I will try to save the polygonal character of the planking, if possible. I do not currently know whether this succeeds - we'll see...

 

I made my plan studies only in 2D. Therefore I can't determine the exact plank geometry on a 3D-model. So, I was thinking about what has to be done to obtain a sufficiently accurate approach with little effort. So, I conceived a simplified representation of the off winding of the frames and planks.

 

So, what do I know about the real geometry of the planking? What can we deduce with little effort from the 2D drawings?

 

- I know the true shape and lengths of the rabbet.

- Further, I can construct the true length of the deck edge on simple manner. Therefor I draw the clamp in its off winding and then I'll take measurement on the arc length at its outer edge.

- Next I choose the lengths of polygon turns of the individual frames (without keel).

 

post-14773-0-63961700-1421746279_thumb.jpg

post-14773-0-44066300-1421746285_thumb.jpg

 

In the next step, I project this determined true lengths in a 2D drawing. What I get here is a simplified flattened side of the hull, with almost real lenght of the rabbet, true length of the polygon turns (frames) and true length of the clamp outer edge.

 

I pronounce it clearly: This is a simplified representation, since the angles and edge lengths aren't correct on the inside of the grid. This error based on the fact that in this drawing concavity and convexity of the hull are not sufficiently taken into account. I still hope that this drawing fulfilled my intention - the hope of finding a harmonious arrangement of the planks which can be applied to the model.

 

Now, I have to drawn (by trial and error) up the plank hallways in a way, that the result shows a harmonic division. Narrow running planks on the bow and stern. Fan-like planks in concave surfaces. So finally I found a harmonious division of the planks - as intended.

 

post-14773-0-97855900-1421746465_thumb.jpg

 

All this I have balanced with my findings, which I have received by studying the photos of "Stavanger":

 

- Total Number of planks.

- Number of planks above and below the CWL.

- Direction of the plank joints.

- Decrease and increase of plank widths.

- Relations of the width of planks with each other.

- and so on ...

post-14773-0-18762700-1421746528_thumb.jpg

 

I must confess, I was not 100% sure whether the transfer to the model will really work with sufficient accuracy. Therefore trial basis, I've done a transfer of the division onto the frames and the entire model was sheerd/streamlined with a rubber thread.

post-14773-0-01060300-1421746667_thumb.jpg

 

... and it works!  :) 

 

It works at least for the construction of my double ender. If someone would apply this method to a different hull form, I would be of course very interested in the result ... I am also interested in other methods of creation of a harmonious division on complex surfaces – certainly, questions and comments are welcome.

 

Regards

Mike

Mike the strings are very innovative, what I like about this method is that our eye is very discerning at catching irregularities in the flow when there are a group for reference. Your strings look like 3D lofting in miniature.

Good morning everyone

 

Thanks to all who are following along, commenting, for the appreciation and for pressing the like-button!

 

@Patrick

Regarding the approach: Yes, I like to cope these things first mentally, the implementation then it's much easier for me.

 

@Matija

Oh thanks! I just hope that I can learn as fast as the build grows - but I know, these are my own expectations ...

 

@Michael

Yes, you're absolutely right. It's really phenomenal, how fast and faultless the eye perceives differences from a series - the eye is a merciless judge!

Hello everyone

 

I've decided to plank the hull in thickness of 3mm (lime tree). Unfortunately, I have found only board lengths of 50cm. Because my longest planks measure approximately 120cm, and because I will not have the possibility to add my planks over the thin frames, was I forced to glue these 50cm boards from the outset.

 

post-14773-0-05482100-1422138480_thumb.jpg

post-14773-0-36518100-1422138501_thumb.jpg

 

In a further step, I have fixed strips of  transparent paper on the frames. Thus I could my marked plank arrangement transferred back to these papers. The corresponding points will be connected with spline curves. For this purpose, a flexible strip of balsa serves me - finally, I've found the requested and true geometry of the planks in 2D!

 

post-14773-0-59204000-1422138638_thumb.jpg

post-14773-0-75430700-1422138581_thumb.jpg

 

In the next step, this geometry is transferred to the boards, by using carbon paper. It is of course aware that the construction of such planks will be cheating a little bit, because in this way the grain of the wood will disagree, it is considered in detail. Correctly I would watering, cooking, steaming, turning, pulling, pressing straight planks - what do I know ... I deliver me from this feat of strength - as you all know, to the end the hull will be completely painted.

 

So, I temporarily put together two boards with double-sided carpenters tape and grab the bandsaw. This two-in-one of course has the advantage, that I get two perfectly identical planks in one step. Then the blanks will be planed to thickness ...

Hi Mike

 

The Colin Archer hulls were renowned for their broad beams, beautiful lines and inherent seaworthiness.  Nowhere is this more apparent than in the last few photos of the partially planked hull. The planking look great so far, as well.  Will you be putting a second layer on as well?

 

Cheers

Hello Patrick, Dimitris, Row, Michael, John and all the other visitors of this workshop

 

As always your feedback means a lot, also all the likes - thanks!  :) 

 

@Patrick

... yes, indeed, Colin Archer's RS-boats often had very wide planking hallways. If we take a closer look at it, it is obvious, that also the strongly conical narrowing of the hallways is a characteristic - but this is perhaps typical for all types of double-ender (see some pictures below).

 

... the hull shape of the double ender distinguishes itself by a high stability even in heavy seas, in particular the excellence on downwind and strong cross sea. Therefore, lifeboats are often constructed as a double ender. Another feature of that seaworthiness is the obvious functional design. The RS-boats are totally subordinate to functionality, there is nothing which a style or formalism would belong (to this some pictures below).

 

... I haven't provided a second planking layer, the current dimensions are in accordance with the dimensions of the finished - by the way, the RS-boats all had a double hull, but on the inner side of the frames and also this inner shell was sealed (see section below).

 

@Row

... yes, I can confirm, that the geometry trick worked perfectly. Unfortunately I can't refrain from working on certain areas with spatula. I'm also glad that the hull will be completely painted, so I can accept the local rework - for the first time, I am therefore quite satisfied with the result, despite some fails. Thus I learned a lot - but I freeze a little in awe, when I look at all the spotless craftsmanship on planking by the masters at Modelshipworld  :huh: 

 

@Dimitris, @Michael, @John

... what will I say? -Thanks a lot for your great statements!  :) 

 

At the moment I'm still working on planking. I'm slowly making progress, because the current workday and family demands much from me. I don't want to complain - it's all right. What I wanted to say, I will be back on my build log with the finished planking. Until then ...

 

Regards

Mike

Hello everyone

 

Thanks all of you for the like-buttons and for your visits in this workshop!

 

@Igor

 

Thank you for posting this beautiful sketch.

 

Although I already knew this sketch, I not knew that it is from the book of Tor Borch Sannes, because I not own this book. I'm not sure, but I think it's only antiquarian available - once I will do some searches about that ...

 

... "Stavanger" has done some slow progress, but the planking is yet still not finished. So, I can show you only some pictures of these unfinished state. At the time the build is progressing slowly, but I have invested much time in strategies to the topic, how I can achieving my expectation concerning the deck - I like to report more about that later ...

 

Best regards!

Mike

Hi Mike,

Unfortunately, I have no this book too, but I read article about lifeboats by Colin Archer in the magazine "Boat and Yacht" and there was a reference with two drawings from this book - http://lib.sportedu.ru/Mirrors/Www.katera.ru/172/172_10.htmlhttp://lib.sportedu.ru/Mirrors/Www.katera.ru/172/172_10.html

 

Best Regards!

Igor.
