Shaped charge casing cutter

A method of filling a collective tolerance space between a plurality of adjacent shaped charge explosive modules, wherein the steps for the method comprise:

• assembling said plurality of adjacent shaped charge explosive modules in a circular or substantially circular configuration, wherein each of said plurality of adjacent shaped charge explosive modules comprises substantially radially aligned side planes;
• and
• inserting at least one shim of paper between at least one pair of said substantially radially aligned side planes of said plurality of adjacent shaped charge explosive modules.

A shaped charge pipe cutter comprising:

• a plurality of shaped charge explosive modules aligned in a substantially toroidal ring, wherein each of said plurality of shaped charge explosive modules comprises substantially radial side planes, and wherein at least one paper shim is inserted between said substantially radial side planes of an adjacent pair of said plurality of shaped charge explosive modules.

A casing cutter comprising:

• a substantially toroidal ring of explosive material having a V-groove outer perimeter, wherein said explosive material is segmented into a plurality of modules having substantially radial side planes, and wherein adjacent substantially radial side planes of at least two adjacent modules of said plurality of modules are separated by at least one paper shim.

A shaped charge casing cutter comprising:

• an annular ring of explosive having a V-grooved outer perimeter, wherein said annular ring is segmented into a plurality of radial modules, wherein each of said plurality of radial modules comprises substantially radial side walls, and wherein at least one paperboard shim fills a space between at least one pair of adjacent substantially radial side walls.
