Abstract
An air gun pellet is formed to include providing a pellet member having a conical skirt, to include a pellet head along a pellet axis, with a skirt cavity directed into the skirt and a head cavity directed into the head coaxially aligned along the axis, wherein the skirt is arranged for filling with a solder insert, whereupon subsequently, a bore member is directed coaxially through the pellet member coextensively thereof.
Claims3
An air gun pellet forming method, comprising,
- providing a pellet member, wherein the pellet member includes a truncated conical skirt having a free annular edge, and
- the pellet member further including a pellet head fixedly mounted to the conical skirt spaced from the annular edge coaxially aligned along a pellet axis, wherein the pellet head includes a pellet head forward wall, wherein the forward wall and the annular edge are arranged parallel relative to one another and orthogonally oriented relative to the pellet axis, and
- a pellet head cavity is directed into the pellet head from the forward wall, and a skirt cavity is directed into the conical skirt from the free annular edge, and
- including the step of providing a first drill having a first diameter and forming by use of the first drill, a first bore hole coaxially aligned along the pellet axis directed into the pellet head cavity, and
- the step of providing a second drill, wherein the second drill is defined by a second diameter, the first drill having a first diameter, the second diameter being less than the first diameter, and the second drill is directed coaxially along the axis extending from the first bore hole coextensively through the pellet member projecting to the annular edge medially thereof to form a second bore hole, and
- the step of filling the conical skirt cavity with a flowable material and subsequently permitting said flowable material to solidify within the skirt cavity prior to directing the second bore hole coextensively through the pellet member, and
- the step of providing an abrading tool and directing the abrading tool over the second bore hole providing an uninterrupted smooth planar surface along the insert simultaneously removing burrs formed during formation of the second bore hole, and
- the step of providing the flowable material includes employing a solder rod and melting the solder rod with a solder gun member and directing the flowable material into the skirt cavity.
