Production of a still
No matter how the special shape of a still turns out. The Boben team must produce the specified curved shapes in a reliable manner.
The raw material is always sheet metal made from 99.96% pure copper to standard in various thicknesses.
After the basic shapes of circles, segments, etc. have been cut out of the copper, these sheets are bent into cones with machine-driven hammers and welded at the joints, just as in the old days. In the past, rivets were used or the joints were soldered. Today, gas-shielded welding has established itself as the best and most convenient method of joining.
The copper is still very soft in its raw state and can be easily moulded into a three-dimensional shape using hammers. Simple cylinders can be turned into spherical sections, ellipsoids or free-form surfaces according to the customer's wishes. However, hammering also serves other purposes. The irregular surface of the weld seams is smoothed, as can be seen in the left part of the picture above.
Finally, the entire surface is hammered again to solidify the surface layer of the soft copper when cold. Finally, the finished mould is sanded and polished to create the familiar shimmering copper surface. At the very end, only the outside is coated with a clear protective lacquer.
