Claim 11:
12. A steel barrel rotation assembly for rotating a steel barrel during a manufacturing process, said assembly comprising:
a base being positionable on a horizontal support surface, said base having a bottom surface, a top surface and a perimeter edge extending between said top surface and said bottom surface, said base having a lip extending upwardly from said top surface, said lip being spaced inwardly from said perimeter edge, said lip extending around a full circumference of said base;
a plurality of legs, each of said legs being coupled to and extending upwardly from said base, each of said legs being disposed on said top surface of said base, each of said legs being positioned against said lip, said legs being spaced apart from each other and being distributed around a full circumference of said lip, each of said legs having a distal end with respect to said top surface of said base;
a mounting disk being attached to said plurality of legs such that said mounting disk is spaced upwardly from said base, said mounting disk having a lower surface and an upper surface, said distal end of each of said legs being coupled to said lower surface such that said mounting disk is aligned with said base, said mounting disk having an opening extending through said lower surface and said upper surface, said opening having a bounding edge, said bounding edge having a continuously arcuate portion defining a circle, said bounding edge having a rectilinear portion defining a parallelogram extending away from said circle, said continuously arcuate portion being centrally positioned on said mounting disk;
a rotation disk being rotatably disposed on said mounting disk wherein said rotation disk is configured to have a steel barrel being positioned on top of said rotation disk, said rotation disk having a bottom side and a top side, said rotation disk having a diameter being greater than a diameter of said mounting disk;
a sleeve being coupled to and extending upwardly from said rotation disk wherein said sleeve is configured to restrain the steel barrel on said rotation disk, said sleeve extending upwardly from said top side of said rotation disk, said sleeve having an outer surface, said sleeve having a diameter being less than said diameter of said rotation disk such that said outer surface of said sleeve is spaced inwardly from an outer edge of said rotation disk, said sleeve being centrally positioned on said top side of said rotation disk;
a plurality of couplers, each of said couplers being coupled to and extending away from said outer surface of said sleeve, said couplers being spaced apart from each other and being distributed around said sleeve, each of said couplers having a hole extending through a respective coupler, said hole in each of said couplers extending along an axis being perpendicularly oriented with respect to said top side of said rotation disk;
a drive unit being coupled to said mounting disk, said drive unit mechanically engaging said rotation disk, said drive unit rotating said rotation disk when said drive unit is turned on wherein said drive unit is configured to rotate the steel barrel, said drive unit comprising:
a primary gear having an upper side and an outer edge, said outer edge of said primary gear comprising a plurality of first teeth being spaced apart from each other and being distributed around a full circumference of said outer edge of said primary gear, said primary gear being attached to said rotation disk having said upper side of said primary gear abutting said bottom side of said rotation disk, said primary gear being positioned in said opening in said mounting disk having said primary gear being surrounded by said continuously arcuate portion of said bounding edge of said opening;
a motor being coupled to said lower surface of said mounting disk, said motor having an output shaft, said motor being aligned with said opening in mounting disk, said output shaft rotating in a first direction when said motor is turned on;
a drive gear being coupled to said output shaft of said motor having said drive gear being surrounded by said rectilinear portion of said bounding edge of said opening in said mounting disk, said drive gear having an exterior edge, said exterior edge comprising a plurality of second teeth being spaced apart from each other and being distributed around said exterior edge, said second teeth engaging said first teeth on said primary gear such that said drive gear rotates said primary gear when said motor is turned on for rotating said rotation disk;
a speed control being mounted to a respective one of said legs, said speed control being electrically coupled to said motor, said speed control including a knob being rotatably disposed on said speed control, said knob being positionable between a minimum position and a maximum position for adjusting a rotational speed of said motor between a minimum speed and a maximum speed; and
a power cord being coupled to and extending away from said speed control, said power cord being electrically coupled to said speed control, said power cord having a distal end with respect to said speed control, said distal end having a male plug being electrically coupled to said distal end wherein said male plug is configured to be plugged into a power source comprising a female electrical outlet;

a pad being positioned on said rotation disk wherein said pad is configured to have the steel barrel resting upon said pad when the steel barrel is positioned on said rotation disk, said pad being comprised of a resiliently compressible material wherein said pad is configured to inhibit noise resulting from the steel barrel being hammered when the steel barrel is positioned on said rotation disk, said pad being positioned on said top side of said rotation disk having said sleeve surrounding said pad;
a plurality of holders, each of said holders being slidably disposed on said sleeve, each of said holders extending upwardly from said sleeve wherein each of said holders is configured to engage the steel barrel for securing the steel barrel in said sleeve, each of said holders comprising a leg and a foot, said leg of each of said holders having a distal end with respect to said foot, said leg of each of said holders having a threaded portion positioned adjacent to said distal end of said leg, said leg of each of said holders extending through said hole in a respective one of said couplers on said outer surface of said sleeve such that said foot of each of said holders is spaced upwardly from said rotation disk having said foot of each of said holders being directed toward each other wherein said foot of each of said holders is configured to abut a top of the steel barrel; and
a plurality of nuts, each of said nuts being threaded onto said threaded portion of said leg of a respective one of said holders, each of said nuts being tightenable against a respective coupler thereby urging said foot on said respective holder downwardly wherein each of said nuts is configured to tighten said respective holder on the steel barrel.
