" In the description of the forge, an old rivet hammer was mentioned, which was the predecessor for the air hammer. The introduction of the air hammer led to a reduced working procedure and less staff as a rivet gang could be reduced to one man.
When one considers the old-fashioned rivet hammer, it is hard to understand that it was in balance. The handle is positioned in a third of the approximately 20 cm long hammerhead with a 30 mm face.
History tells us that thousands of ships were riveted in this way until the invention of the air hammer. Today, we weld the ships together and one welder welds the iron together, where before it took a three man rivet gang to do the same work."
