发明名称 Device and method for construction of baffles from engine block freeze plugs
摘要 A device and a method of using the device for construction of baffles that may be used in suppressors or solvent traps for firearms out of metal cups sold as engine block freeze plugs. The device has a bottom die, a top die and an alignment cylinder. The metal cup is transformed into a baffle by placing the metal cup on the bottom die, placing the bottom die inside the alignment cylinder, placing the top die inside the alignment cylinder, and applying compressive forces to the bottom die and top die. A hole may be drilled in the center of the baffle by placing a drill bit into a top die center hole completely penetrating through the top die and coaxial thereto, and drilling through the baffle, the drill bit passing into a bottom die center hole penetrating at least partially into the bottom die and coaxial thereto.

主权项 1. A baffle forming device comprising: an alignment cylinder with an alignment cylinder cavity therein that is cylindrical and has open ends, the alignment cavity with an alignment cylinder inside diameter; a bottom die with a bottom die body having a bottom die block coupled to a bottom die base, wherein the bottom die is a monolithic piece, wherein the bottom die block and the bottom die base are cylindrical and coaxial, wherein the bottom die base has a bottom die base outside diameter and the bottom die block has a bottom die block outside diameter, wherein the bottom die base outside diameter is larger than the bottom die block outside diameter and no larger than the alignment cylinder inside diameter, wherein the bottom die block has a conical cavity therein and coaxial with the bottom die, the conical cavity with a conical cavity base that is open, wherein the bottom die has a bottom die center hole that is coaxial with the bottom die, wherein the bottom die center hole joins the bottom of the conical cavity and extends at least partially into the bottom die base, wherein the conical cavity has conical cavity sides, wherein the conical cavity sides and the conical cavity base define a bottom die cavity angle; a top die with a top die base coupled to a top die block, wherein the top die base is cylindrical and has a top die base diameter that is no larger than the alignment cylinder inside diameter, wherein the top die block is shaped as a truncated cone, wherein the top die block has a top die block conical base that is adjacent to the top die base, wherein the top die has a top die center hole that is coaxial with the top die, wherein the top die center hole extends completely through the top die, wherein the top die block has top die block sides, wherein the top die block sides and the top die block conical base defined a top die angle, wherein a value of the top die angle matches a value of the cavity angle; and wherein the top die and the bottom die are configured to fit slidingly within the alignment cylinder cavity.
