Very nice clean soldering work on these pieces. That is a challenge that you were successful in completing. Rich (PT-2)

Testplacement of the ruder.
Yes, they are small ruder hinges.
But they were soldered with a normal 40 Watt soldering iron. The components were fixed with pins on a wooden board (no burning fingers) and soldered. The finishing was done with needle files. Somehow the ship model builders are also goldsmiths. With a little practise on waste materials and patience it will succeed. There are so many excellent metal works to see here at "Shipsofscale". Just try and practice! You will get better and better!

Such a beautiful ship! Great job on the intricate soldering!
Thats a beautiful build Thomas.
Thomas,
What do you mean by 'internal' and 'external' dimensions?
Nice work!

In addition to your fine soldering work I really like the shape of the tiller!! Rich (PT-2)
Hi Janos!
The problem of component size is due to lasering. The laser is guided on the construction lines and thus also cuts out the components too small. The laser should cut outside, that is, in front of the lines and not on them. The right rudder was freed from the carbon and is too narrow.
In technical drawings, the lines are part of the component. Nobody draws a component of 10 mm and makes the dimensions outside the 10 mm. In the case of the rudder, it was cut on the lines and building substance is already missing (only 9,4 mm remains). And then the grinding takes place to clean.
An example: If I cut deck planks myself to 5 mm wide and lay them next to each other, I will have 50 mm for 10 pieces. With lasered deck planks, it will happen in most case that after cleaning the planks I will only have a width of 47 mm. An unpleasant event.

Thanks for the explanation, Thomas!
Does the laser run on the inside of the line every time or does it depend from which direction the laser arrives at the part? Ie. does the cutter run on the outside edge of the line if the laser 'arrives' from the outside?

Hi Janos!
Dave Stevens once gave me a nice explanation of these laser errors and how to laser properly.

I have been creating laser cutting files and working with laser cutters for years.
the laser does indeed have a kerf (width if the beam) the laser i am using now is .012 thousandths so when i finish drawing a part i will offset the lines .012 + .006 for a total of .018 which will take into account the kurf plus a little extra to clean the part. The parts you are showing in post #1 is a poor job of laying out parts.
When you have something like a scarf where 2 parts come together you will be .024 off and parts will not fit right.
looking at this cutting file
when you zoom in close the black line is the keel part the red line is the laser path so the edge of the beam is just shy of the edge of the part

This conversation is most informative for me to better understand the dimensional issues. I did have a problem in laying deck planks which were stock and not laser cut, with the carpenters glue was absorbed causing the plank width to expand and those went from a perfect dry fit to not setting down properly causing a finishing issue. Thanks for your information above. Rich (PT-2)
Slowly continues with the rudder. The hinges are mounted with epoxy resin and the tiny nails from Dry-Dock Models & Parts are used. First they were shortened to 2,5 mm. Left original size, right shortened. The nails are very stable and do not bend.
In the already glued hinges the holes were pre-drilled with a 0,3 mm drill.
And finally the nails were glued in with resin.

The sailor's arms become heavy when he has hold them up so high on the tiller for a long time.

Wonderful workmanship Thomas, it is a pleasure to follow you log.
Your rudder fittings are very well done. What is the source of your crewman and the scale? I need to recruit some crew members. Rich (PT-2View attachment 259671

Hi Rich!
The figures are available in different scales. They are made of white metal and still need to be painted. The three right figures are scale 1:44-1:56. They were painted in the colors according to the book "The 74 Gun ship, Vol. 4" by Jean Boudriot.
With the search function: "Figuren" appear the currently available sailors.

Nice guys Thomas, beautifully painted. It makes any ship more alive.
Yes, a few of those might do for fishermen, not merchant or military naval crew. Thanks, RichThanks for the likes and comments!

Very good work - good to see, that you also use the small nails for the rudder hinges - on my opinion a very good solution and in scale 
Construction and assembly of the stern lantern.
Some individual parts of the lantern according to the construction drawing.
The sequence of the soldering process. Here you must have some practise in soldering, otherwise already soldered components heat up and shift or stick at once completely to the soldering iron.
This is how the lantern looks like after the Boudriot drawing.
Liquid glass for the glazing.
Now the two lateral support struts are missing.
