Started with the frame for the lantern. The old drawing shows that it is on a deck plate:
The dimensions are shown: 4900 x 1140 x 6. In scale this becomes 98 x 22.8 x 0.12 mm. That's why I bought the Evergeen 0.13 mm plate.
The frame made of the lantern:
Made divisible into 2 halves. I will make the lantern in its entirety later. This can then be placed over the frame when both halves are against each other. Just like the hatch of the forepeak.
A print made from part of the drawing and cut the plate size out:
Cut out all the recess so that it can serve as a mold.
A test installation around the mast tube and kossing:
The cover plate should actually also be located under the profile on the side of the mast tube and kossing. That the profile is riveted to the plate. But then I would have had to follow a completely different order of construction. Now I put the plate against it.
After the necessary fitting, measuring and cutting to size, the two plate halves were placed on the deck beams and the 2 frame halves were placed on top of them:
Then cut away the pieces of center profile to the size of the opening.
An extra piece of profile was added lengthwise on both sides of the opening between both deck beams:
The piece is highlighted in blue for clarity.
This is what the lantern looks like on the Balder from the inside:
Left: The view to the galley, seen from the forecastle, standing next to the stairs. The arrow points to the lantern.
In the middle: The lantern stands on the deck plate and is otherwise unfinished.
Right: This is in contrast to the light in the forecastle. This has been completed on the current Balder. But the old specifications state that only the deck beams were finished and the metal of the deck plates was looked at. I think I'll stick with the latter.
The now installed deck plate provides extra strength to the construction, especially to the deck beams themselves.
I'm going to adjust my plan slightly and now first install the rest of the deck plates and stringers on the foredeck. That gives extra strength in the areas where the frames for the entrance and lights will be placed and where I also have to remove pieces of the center profile.
