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.
The reason for this is to see at which pressure the grenades will crush.
Each small line is 20Bar and represents 4.2Tons of force.
