Now this is really interesting, I’m always fascinated by how two modelers will approach the same task. My superstructure was a bit of an experiment, I wanted to see if I could build an extremely light structure so that I could drastically reduce top-weight in future models ( particularly models with a high free-board, shallow draught, narrow beam and large superstructure). Of course Bismarck doesn’t need this but I thought that the model was a big enough “playground” to try my ideas and reduced top-weight certainly could do no harm, after all the resin guns and boats etc are quite a weight.
So far the experiment has proved pretty successful, I used mostly that plywood that has about the same thickness as paper on a framework made from 3mm square pine. Any areas that had rounded edge( like the front of the section you just made had balsa inserts so that I could sand the edge to the correct profile.
I’m hoping to build a model of a destroyer my grandfather served on and the technique should help produce a model that doesn’t roll onto it’s beam ends every time there’s a puff of wind. ( I have the hull but there are about four or five projects lined up before I start that one!
