Yes, it's always a balance between not curving the metal and getting a deep texture imprint. These metal samples were very thin but thicker metal requires less pressure and curves less.
Generally speaking the thicker the metal, the more your chosen texture can be pushed into that metal but we regularly use anything between 0.3mm - 3mm thick.
Bitte warum so ein video über einen ganz banalen Arbeitsvorgang? Vielleicht sollte ich auch mal ein Video machen über den Grbrauch meines 300gr-Hammers?
