Disassembly tool for Winchester type shotgun primers

grabcad

The disassembly tool I designed for Winchester shotgun primers enables the removal of primer compound for homemade electric detonators. Created as part of an expedient bomb technology development program, this device requires thick leather gloves and full face shield when in use. Disassemble one primer at a time, using a slightly wet wooden toothpick to remove compound while holding it with pliers. Avoid working near the pile of primers and maintain a barrier between you and the pile to prevent accidental detonation. With careful application, this tool safely disassembled over 3000 primers without any mishaps; the primer compound can detonate under impact but can withstand high forces when dry. The pin that separates the primer is made from a regular HSS drill bit's shank.
