         9 . The drum of  claim 8 , wherein the cylindrical sidewall includes a plurality of apertures proximate the first end, the drum further comprising a chime including a first wall and a second wall spaced apart from the first wall, the first and second walls including a channel therebetween configured to receive the first end of the cylindrical sidewall, the first wall having a first surface proximate the channel and a third projection projecting from the first surface into the channel, the third projection including a third engagement surface, the second wall having a second surface proximate the channel and a fourth projection projecting from the interior surface into the channel, the fourth projection including a fourth engagement surface;
 wherein the third projection projects into one of the apertures proximate the first end of the cylindrical sidewall and the third engagement surface engages the sidewall to couple the chime to the sidewall; and   wherein the fourth projection projects into another of the apertures proximate the first end of the cylindrical sidewall and the fourth engagement surface engages the sidewall to couple the chime to the sidewall.   
     
     
         10 . The drum of  claim 9 , further comprising a top closure configured to be coupled to the chime to close the first end of the cylindrical sidewall. 
     
     
         11 . The drum of  claim 8 , wherein the first wall includes a third projection projecting from the first surface into the channel, the third projection including a third engagement surface, the third engagement surface being axially offset in a direction parallel with the longitudinal axis from the first engagement surface; and
 wherein the second wall includes a fourth projection projecting from the second surface into the channel, the fourth projection including a fourth engagement surface, the fourth engagement surface being axially offset in a direction parallel with the longitudinal axis from the second engagement surface.   
     
     
         12 . The drum of  claim 11 , wherein the second projection is located radially between the first projection and the third projection; and
 wherein the third projection is located radially between the second projection and the fourth projection.   
     
     
         13 . The drum of  claim 12 , wherein the first and second engagement surfaces are generally parallel and generally located in a first plane perpendicular to the longitudinal axis;
 wherein the third and fourth engagement surfaces are generally parallel and generally located in a second plane perpendicular to the longitudinal axis; and   wherein the first plane and the second plane are generally parallel and are non-co-planar.
