These grenades are collector items and are REAL grenades from WWII ! The explosive charges were removed to make them legal for collectors.
If these grenades were still live they would destroy the hydraulic press and the entire workshop with them.
– This press was done with regulated hydraulic pressure.
– When pressing the grenades we gently increased the pressure with a pressure regulator.
– This is why the pressing goes allot slower then the previous videos.
Each small is 20Bar and represents 4.2Tons of force.
