Hi Marco,
i wish you much fun with this huge build.
I have a question about the framework:
Is it intentional, that both underwater and waterline framework are connected at this stage? I don't know this model kit and can only speculate. I know from other model kits that you can build the whole underwater hull seperately from the waterline hull. You can connect these 2 groups later. I attached 2 pics of an example to show what i mean. It's the model "Altmark" by HMV (1:250). Both groups can be attached to a glass plate (to work against "warping") and are put together much later on the 2 shown cones sticking out from the underwater base plate. A rather good thing, i guess.
Just wondering, if your model allows the same technique...
Looking forward for more
Kind regards
Lars
