Today it rained all day, so I had enough time to finish the design of the cant frames





The Bollard Timbers and Hawse Pieces are missing to complete the planning of  framework.
The individual components and the frames I'll draw later during the build.

Next, the construction of the two-stage slipway is on the ToDo list, then I can lay down the keel for the model.

In the moment I am working on a corrected disposition of frames drawing for my sloop
The basis are
 
DOF of Cygnet (ZAZ4691) Dimensions given in "The Ship Builders Repository", 1788 (1) Dimensions given in Steel "The Element and Practice of Naval Architecture", 1805 (1) Antscherl TFFM, Volume 1  
(1) The dimensions I took from Allan Yedlinsky "Scantlings of Royal Navy Ships 1719-1805". The original books are unfortunately to expansive for my hobby budget.
 
The different timbers for the keel and the knee of the head, I took from David's book. I only adapt these to the other proportions.
 
After a lot of measurements in the DOF of Cygnet and comparing with the given dimensions, I decided to follow Steel. I am really surprised how well the frames fit to the original drawing. If you compare the numbers of the sweep ports with the original drawing, yo see that there is one port missing, because it was not shown on the As built drawing.
 

 
In the moment I am drawing the cant frames, which is much easier as by my second project.

Welcome on bord, Antony
 
The completion of the hull of my control model in the region behind the last frames has attracted much longer than expected.
When planning the last phase of the construction I realized that the body plan of the original drawing and therefore my reconstruction at the top of the last two frames is too narrow. So back to the drawing board and the frames 19 and 20 newly constructed. The hull at frames 20 is now about 1 mm wider in the region of maximum breath than originally. With the help of several buttok lines and the new water lines I have also redesigned the transoms

I haven't add all changes on the test hull, so you can see in the pictures the not entirely harmonious course of the lines.





The first step of my little project -the reconstruction of the lines- is complete.
In between, I have asked myself several times whether the construction of the half-model was even necessary. After the problems in the reconstruction of the transoms and fashion pieces, that define the shape of the stern, have identified, the construction of the test model was more than worth. I am happy to have the mistakes now and not found during the construction of the POF model.

In the next few weeks I'll construct keel, frames and all other components that are needed to build the hull. In autumn I like to start the construction of the POF model. Until then, one last picture which shows the side view of the test hull.
 

This is the current stand of my reconstruction. As you see on the pictures I've need some putty after sanding. This has two reasons.
I've sanded to much on frame 20 The lines for the transoms have some smaller mistakes. During the last month I've redrwan the transoms. Also I've corrected a small mistake of the maximum breath in this area. In the moment I add the counter timbers to my drawing and complete the half model to check the revised design.

The transoms can not be derived directly from my reconstruction of the body plan.In the half breath plan of the orioginal drawing the form of each timber is indeed located, but does not fit properly on the corrected design. Before starting for the next step I have taken these lines and adjust them so that they match up with my design and also with the position of transoms in Sheer plan.
Subsequently the transoms were transferred to 3mm plywood, sawn and glued on the control model. I 've filles the gaps as usual with poplar plywood. After sanding the area looks like in the following pictures:
 

 

 

 
 

Thanks Johann, druxey, Mike and Nils for your nice comments and all others for the Likes
 
Next I've installed all bulkheads until frame 20 and the filling pieces.
 

 
Then my favourite pastime - sanding
 

 

Then I've started sanding the hull. I've used 60 grid until 120 grid sandpaper for the process. After around one week - I can only work on my model in the evening or at the weekends- I've finished the front half of my control model.
I am very happy with the result
 

 

 

 
To check the curves I use 1mm thick stripes of maple. The found differences are very small. So I think that my reconstruction will work for the checked range.
 

 

 

 

 

With the build of my control model I started at the end of March.

The edges of all frames I've colored black. This will be later a great help by sandig the hull.
The glued surface of the cant frames is very small, so I've glued first plywood stripes on the center board.
To get the correct alignment the colored 5' marks on the frames and the center board are a great help.
 

First half of frame 0
 
Six frames have been installed.
 

 
At this time I've started to glue the filling pieces of polar plywood between the frames. I've used a chess board pattern to avoid the distortion of the frames.


 
Until the mid of April I've installed all frames and filling pieces from the center to the stem on the stem.
The next two pictures show the result of the work. It's looking very horrible
 

 

To check the lines I started to build a half model. For the frames I use 3mm birch plywood, it's for a model in 1/32 perhaps a little small, but I've had a bigger batch at home. All space between the frames I fill with poplar plywood. It's easy to shape but stable enough for the purpose.
I glue the drawngs with rubber cement on the ply woord


 
With a sharp knife I mark every 5' line. The picture shows frame 0:
 

 
All bulkheades and the center are cutted out. The hull has a length of around 1m, which is not as big compared with the new 1/200 model kits of the WWII battle ships.
 

 

Part 1 Reconstruction of the hull lines
 
David Antscherl wrote in his wonderful series about th Swan Class Sloop, that there are a lot of smaller differences between the ships of the class, for example the knee of the head of Fly.
As first decision for my new start I decided not to use the general lines, which David has published. I want to do my own reconstruction. The naval cutter was a first exercise for this project. In January I started with the reconstruction. At the end of February I had a first version of my body plan, which matchs the lines of the historical drawing very well.

The Swan Class Sloop and I have as some of you know a longer history. Two years ago I started my build log for the build in 1/48. A few month later I had to stop the build because I got some problems with my eyes. At the beginning of this year I started again. I decided to change the scale of my build to 1/32.
I hope that some of you are intersted in my build and like to follow my log.

So let's start again
 

Copper plate & bolting on the keel
 
Thank you friends as always. ;-)
 
Horse shoe and fish tail copper plates were attached on the both sides of the keel. Brass wire was used to fix them on the keel. After finishing bolting work, keel, frame and outside planking strakes were oiled with the mixture of linseed oil and turpentine oil.
 
Cheers,
 
Lee

Hi Mick,
 
I'll follow your log with interest. It's a very uncommon type of ship and so very interesting

Welcome on board, Daniel. The work on the llines is finished. In the moment I work on the disposition of frames drawing.
It's very interesting to compare the Cygnet drawing with the Shipbuilders Repository and Steel to get the thickness of the different timbers. And the to compare this with David's results.

Hello friends.
 
The all remaining frames mounted, aligned and bonded.
Now handwork is called for sanding.
Help in this case, belt-sander, long-neck angle grinder
and various sanding blocks.

Last week's progress.

Hello all,
 
Quarter deck almost complete - missing last two beams - somehow I counted them wrong. I still have to add several hanging knee and lodging knees too.
 
Before someone asks, in the before last picture the space for the companionway between the first (lower) two beams is shifted toward left as in the plans.
 
The upper deck below was oiled as there will be nothing else that needs to be glued to it.
 
Regards,
Alexandru

Part 16 – Garboard Strake
 
The planking of the lower hull begins at the keel with the installation of the garboard strake, heavy (7” X 18”) members, bolted through the deadwood and edge bolted into the keel.  At the ends of the ship the garboard strake is expanded into two strakes to begin the upward sheer of the bottom planking and to further strengthen to narrow deadwood at these points.
 
In the first picture the aft section of the garboard has been fitted against the post and is being marked for the insertion of the second strake “stealer”.
 

 
In the next picture the strake was cut to receive the second section and is being held in place to check the final fit..
 

 
This strake members were then glued in place as shown below and over the entire length of the hull with a similar joint for a second strake at the bow.
 

 
Because this strake twists to fay against the curving hull, a lot of clamps were needed.  The next picture shows the aft section after the piece of second strake was installed.
 

 
I did not use dark glue for any of the hull planking since the intention is to paint and sheath the hull later.  Hard maple was used for all of this planking.
 
The last picture shows the forward part of the garboard, with the joint lines emphasized on the image to show the configuration.
 

 
In this picture, it can be seen that the line of the rabbet runs just aft of the joint line between the stem and false stem.
 
Note that in the last two pictures the garboard thins down to match the depth of the rabbet in the stem and sternpost.  The garboard was, of course, installed on both sides of the hull at this stage.  Since it is intended to sheath this lower hull, I did not install any of the bolts, as I would have done on the fully framed version – if I had installed the garboard on that model. 
 
Above the garboard, the planking thickness drops to 4”.  The beginning of that work will be shown in the next part.

Thanks John
 
The beauty of lining off the deck is that it allows you to create a great plan of attack.  If you connect all of your tick marks you will have a really good idea of how it will look.  If it needs adjustment then just sand it off and start over.  You can do all of this before you lay one deck plank.  Imagine if you just wing it and have half the deck planked...you are sunk.  Lining off the hull first helps you avoid this.
 
I will do this at the stern next and then start cutting wood. 
 
Now if you were just going with straight planks nibbed into the waterway,  would you need to line off the deck like this?  Maybe not.   But I think it is worth the extra work.  And keep in mind you want have to cut into your waterway and risk a cutting error with a bad joint while nibbing.  That takes a huge amount of time and careful chisel work.  So its pretty much a wash as far as the amount of time and effort goes.  
 
 
 
The contemorary model of a cutter shown below also has tapered and scarfed deck planks vs. nibbing.   You can see the tapering very clearly here.

Congrats Dan.

I've finished the "Disposition of Frames" drawing.
 

 
I am not quite happy with the position of the timberheads between station line 17 and 19. But this is the position I got from the As Built plan of the Fly.
 
Next I will built my building board and start with the model.

OK, that's IT - she's finished and pics are in the Gallery.
 
There's a Link in my Signature which will take you there.
