The rubber press belongs to an aircraft repair shop. Some years ago I worked with someone from the repair shop and he had permission to use it. I made a wooden plug that was put under a block of silicone rubber with a brass plate on top. Several tons later the back was pressed into shape, with a flange around it to solder to. The cover plates were made the same way. They turned out pretty well, though the birch ply ‘plug’ was crushed a little by the press, this meant the edges were more rounded than we wanted. It did produce a back that looked fairly close to a proper National back rather than the appox shape of Chinese made or the ‘stepped’ shape of Korean ones Pete Just wanted to say that's a really beautiful coverplate!
