Your clinker planking looks really good. Nice progress.

There is coffee and biscuits in the back and free seats up front.

No Glögg ? 😞

 

Oh, yes, the planking came out very nicely !

Sorry wefalck, of course there is glögg!

Still plenty in supply 😉 season is not over yet 🙂 

[vaddoc]

Very nice Hakan!  Came out just fine.

Tomorrow is bank holiday and after that my free time diminishes to that of regular, working people.

Those still exist in Sweden!?

Carl, yes they do. As you most certainly have read in any international paper Sweden has not indulged in total lock down. Blablabla death rates, numbers and all. Anything and everything can be shown with statistics...

Anyway, my line of work is in deployment of medical IT. No shortage of work there I can tell. 😉

A very elegant hull, Hakan.

[Wintergreen]

So, after first day at the office, well, home office for the time being I was eager to get out and finish of the sheer strake.

Apple was equally easy to bend as birch but as it turns out, much harder to sand. Which is a good thing because it holds edges really well.

I will not treat you with any close ups just yet because even if it looks really good and there has been quite a lot filing and sanding the sheer is not exactly where I want it. 

Yesterday I also finished the building board. It will make due for small builds but for my next project I need to build a larger one (oh, a cliffhanger..).

 

Next up will be frames and other internal members. For that I need to revisit the plans in my computer to figure out placement and such. 

Please excuse the occasionally unfocused images. They do however add that airy touch and enhances the subject somewhat 😉

Very nice Håkan, very nifty building stand too. (IT ... yes I know, they can't leave us be enjoy our hobby somehow )

Or as I said to my line manager that I work to get the money to pay for my hobbies and it's  a shame that work so severely affects hobby-time 😄

Very nice planking Hakan!

I fully agree 

 

Great little model 👍

[druxey]

Just found your thread, Håken. You are doing a lovely job on her!

[Wintergreen]

Thank you guys!

 

@druxey - Thanks for your approval! Your build of the Royal Barge was what set this in motion once upon a time. I am of course careful to show only the best angles of the hull 😉 

 

Carvel or lap strake is quite unforgiving and I didn't managed to get port and starboard equal. Port side is a little higher, but that will not be prominent once on display I think.

You can do a half hull display ...

 

I didn't see the difference though ... either minimal difference or very well taken photographs

@cog it's the latter 😄

Hi guys!

Thanks for comments and likes. 🙂 

 

About frames.

At the moment, this thing about clinker-boats does not seem so appealing any more... a Kingdom for a carvel built hull!

Well well, insert words like "perseverance" and "patience" and "long term goal" here. 

I made an effort with a piece of cardboard and a compass to see what the challenges were. And boy, they were many. 
In the first picture that first effort can be seen lingering around in the hull. 

Basically one needs something to take measurements from, like a gantry. 

Then something to lift the measurements with. A caliper seemed like a good choice, but to flimsy and could be guaranteed to be vertical.

A depth gauge on the other hand has all the right attributes for this.

For every measurement a line was drawn on the paper strip to mark its position athwartships. The results can be seen i second picture. For those that can read my figures you will see that the hull is not a perfect mirror image. It's not by much but the eye will catch it if allowed.

 

Next step I guess is to take measurements for all frames and then transfer them to a paper. Cut out, test fit and if okay, transfer to wood and, well, I think you can guess the rest.

 

In the above picture the line that goes across is aft perpendicular. The shorter lines represents the front face of each frame.

In addition to the frames there will be two mast steps and a couple of shorter frames, merely uprights to support thwart by the masts.

 

 

 

[wefalck]

I have seen people glueing together templates for the outside of the (sawn) frames from short pieces of cardboard, perhaps twice as wide as the planks and overlapping each other.

 

Lucky those, who are building clinker-boats with bent frames

 

[bolin]

The method that @wefalck suggest works well when the planks are reasonably wide (above 5 mm or so). I used it on my medieval long ship. When the planks are narrower and more numerous its start to be hard, so on my sloop I am using a method similar to what @Wintergreen is showing, it is much less accurate.

[Wintergreen]

Well, this didn't turn out half-bad if I may say so myself. 😉 

 

They're not glued in place yet since I ponder over finishing.

Now, how did that happen you ask?

My depth probing resulted in this template. A little bit off, but decent. Tricky part was in the bilge and that it has 23 spots to conform to at the same time... and paper is flimsy to work with.

 

So, suggestion from @wefalck was given a thought. I saw @bolin using that method as well. On a bigger subject it would work for sure.

I gave it a try with each paper strip matching 2-3 planks. Not usable in my case was the conclusion. Still to flimsy.

Also, the frames are very similar and only changes shape slightly for each pair for and aft so something that could be used over and over again was to prefer. 

Came up with this idea:

 

Boards of roughly the same thickness as the frames, cut from birch. 15 mm wide (guess that's something like 5/8").

Leftmost in this picture is reference side. Once port template was done, a new reference was clamped on.

 

Pros:

only three planks to ease in to for each template board.

can be used for consecutive frames with just minor adjustments.

clamps easily to the gantry and can be managed without fiddliness (not a word, I know, but you know what I mean)

Once satisfied it is a simple task to take them all, secured with a tape on the far side and clamps at the ends and transfer result onto  framing material (apple, 2,3 mm thick).

Cons:

Well, not a con really, but it takes time. But that's true for all things considered in a 1:30 ratio to true world. 😉 

 

And an in-between shot with port frame half done.

I even managed to get the limber holes in, or what they're called. 🙂 

Best of all - it didn't take all day to produce one full frame!

 

Also, thanks for given attention with likes and comments!

 

[wefalck]

Your tracing contrapment is a bit like those DIY tracers with a stack of steel rods in a frame ...

 

It occured to me, that one could also use one of those consumer laser-scanners to produce cross sections and print them onto paper templates.

Yes, I pondered over such a thing first. But several reviews said it takes a bit of force to form the rods. So, I came up with the above idea, which proved useful.

A laser scanner would surely work, but then I try to keep things simple and always the K.I.S.S rule in mind (Keep It Simple, St...).

[bolin]

A very interesting approach to finding the angles of the planks. The result looks good as well.

[vaddoc]

Good job Hakan! I thought the first method was desperately difficult but the last method seems elegant and the frame came out fine. Indeed, the scale make this task even more difficult.

The boat is coming along fine

[wefalck]

Yes, avoiding to distort the shell, while fitting the frames would be very important.

[Wintergreen]

Just a wee update so you I'm still at it. 😉

 

Main problem now is outside temperature. Since my workshop is heated by an air-air heater, when mercury drops below -5 Celcius it can't really keep the shop warm. So, extra heater is engaged. Starting out at around 12-13 degrees inside in the morning, temperature slowly raises to 15-16 at lunch time, and if lucky, another degree during afternoon. 

The last couple of days it has been lovely winter with down to minus 10 Celsius. Say no more.

(My workshop is adjacent to the garage btw).

 

Anyway, the task at hand is cutting frames. I manage one half frame per day during weekdays and maybe 1 to 1.5 full frame per day on weekends.

The template sticks works really well. Frames 4 to 8 are done and waiting for fastening. Currently work is on the after most frame, no 9. No 4 and 9 also has a maststep partner.

 

At the moment a break was needed since I realized that I need to redo frame no 4. 

 

However, on another note I got really excited today since the plans for my next build arrived as pdf:s. Yay!

That'll be fun when time comes. Need to be done with this one first though.

 

As always, thanks for Likes and comments! Appreciated 🙂

Hahan, you are living very nicely there, just like in a post card. I have the same temperature problems in my worshop. Fortunately it is never as cold here as in Sweden. Yesterday we had the first snow of this winter here, but today it will melt away. Wednesday the weather forecast is already showing +10 degrees Celsius.

Håkan, that's a beautiful location ..... I miss the snow in one way, but lately having temps at 12 °C it's nice not to have to worry about slick roads .... however the workshop of mine is cold... has a solid concrete pad radiating the cold from the ground into the shop.

Heating solution is under consideration.

Now as for the Kåg, what you have done is beautiful, and I am looking forward to more of it...

Bästa hälsningar

Beautiful country Sweden.
We went there a few times in the summer by car on vacation.

Nice house and great work on the model.

[Ondras71]

Very beautiful wooden line Hakan. I look forward to continuing. Ondras
