How to work on a hull?

[Wilfried]

Hello gentlemen,

I'm not sure, was it really such a good idea?
Well, alright. My choice is a very old vessel from the very early days of the young German Bundesmarine. We get 2 canadian built fishing vessels used by the Royal Navy as escort and subchasers of the Isles class.
HMS Dochet T 286 later A50 Eider and HMS Flint T 287 later as A51 Trave.
Eider and Trave - after modifications - used as training vessels. Classified as tender.
In 1963 - time of the Cold War - Trave was rebuilt into a spy ship for electronical surveillance in the Baltic Sea. Equipped with antennas for COMINT - communication intelligence and ELINT - electronical intelligence. Till 1971 the Trave was an uninvited guest in the Baltic Sea - especially outside the German territorial waters.

Now let me see what we have; the bible of all friends of the German Navy includes a line drawing - unfortunately the modified version of the Eider into a minelaying and -sweeping ship and some various pics. I would like to make the Trave first so I scan and scale the drawing up to 250 % reaching my favourite scale 1:250 ...

The next step in Photoshop was to adjust and sharpen the drawing and directly exported to Freehand, my vector based program for the next steps. Setting the first layer for the drawing and dropping the saturation down to 50 %.
So it's easier - for the first round - drawing the main former of the hull framework.
I correct the stern into the right form as it was before rebulding into a minelayer ....
On the left side you can see a small red rectangle (4 mm) and a black square (9 mm). Both are reference to stay in scale. 4 mm = 1 m is the standard for rails and bulwark and 9 mm is the same in distance beween two decks ... my experience ...? Those little helpers very useful as 7 mm calculating for a human being in 1:250 scale ... :D

Ok., its not very exciting but framework is the mainwork...

With lovely greetings

Hi Wilfried,

the red line is very hard to observe - I captured the picture via clipboard and made my inspection in PSP. The picture is a littlebit noisy - you could get rid of it by selecting a frame around the ship schemes, perform a RGBH analysis, look at the average values, create your noise filter using these data and simply apply the filter - maybe 5 minutes workload.
Whats next ?

Hello, Professor!

I have my hand up with a question....

I gather you found the line drawings from the book you referred to in the post, but how did you scale the drawing to 250%? And did you add the colored base line shown in the last picture of the photoshop workpage?

I hope my questions are not to simplistic but I would like to follow how you do this step by step where possible. Sometimes knowing how to work the software is half the battle.

Cheers!
Jim

Hello Klaus,

sorry for inconvenience; I use screenshots; the noisy grey is result of the used layer ...

Sorry, I forget to remark; the line drawing in the book is 1:625... the red base line I did in Freehand...

Thank you, Professor!

I gather the Freehand is the software from Adobe? I notice you have the Apple version, but I would be using the PC version, hopefully no big differences?

So far, I am following without much difficulty, thanks to your clear instructions. But, just to be clear, I gathered you determined the line drawing in the book is in 1:625 scale and needed to convert it to 1:250 scale...not sure HOW you did that, but I gathered that is what you needed to do to put it in the scale you need for your further work.

Cheers!

You can use every vector-based software just like Corel, Illustrator, Inkscape or Freehand or ....?
For converting the scale drawing I use comfortably a scanner - but you can do it in every copy shop and work on transparency paper later...

Hello gentlemen,

the next step was - and for the screenshot switched off - drawing the main deck and the fore deck (yellow arrows) following the outline of the scaled line drawing. Continuing with the waterline baseplate (blue arrows). All three at the bow modified referring to pictures I've found and observed. After that starting a new layer and setting the guidelines for the frames.
The red arrow shows the "extend line" of the main deck. It will be helpful some steps later ... I hope this all give you an imagination how I start a hull ...

With lovely greetings and see you ...
