Image Number 2 for United States Patent #6561101.

An explosive delay assembly including a housing, the housing includes a continuous elongated sidewall surrounding a region bounded at one end by a top surface, the top surface including an aperture configured for accepting an end booster where the end booster is attached to a ferrule assembly, the end booster and ferrule assembly connected to form a mild detonating fuze including an explosive charge. The elongated sidewalls include a groove emanating from the aperture and threading around the continuous elongated sidewall to a bottom surface and connected to a channel running from the bottom surface to the top surface. The ferrule assembly is wound around the housing within the groove and inserted into the channel to terminate at a top surface region counterbore. The counterbore is filled with an explosive charge.
