1. A can seaming apparatus comprising:
a power tool having a body, an actuator and a chuck;
a frame with a bottom end and a top end, an upper mounting plate attached to the frame proximate the top end of the frame, and a lower mounting member attached to the frame proximate the bottom end of the frame;
a can handling assembly including:
an upper chuck fixed to an axle that extends through the upper mounting plate, and is rotatably coupled to the upper mounting plate, the axle extending beyond the upper mounting plate and structurally configured to be free from obstruction sufficient to allow for an operable attachment of the chuck of the power tool, and wherein the chuck is attached to the axle extending through the upper mounting plate, whereupon rotation of the chuck rotates the axle;
a lower chuck having an axle extending therefrom, the axle slidably mountable to the lower mounting member, with an overcenter mechanism including a handle that is movable relative to the frame to direct the lower chuck between a lower position and an upper position, wherein in the upper position, the lower chuck is directed into position relative to the upper chuck so as to releasably retain a can therebetween; and
a can seaming assembly having a roller frame pivotably coupled to the upper mounting plate, the roller frame having a first roller and a second roller rotatably mounted to the roller frame, with a handle extending outwardly from the roller frame so as to structurally facilitate the pivoting of the roller frame about the upper mounting plate so as to direct one of the rollers toward the upper chuck while directing the other of the rollers away from the upper chuck.
