Claims19
A bucket drum, comprising:
- a drum shell formed from a bucket having a side wall extending between an open first end and an opposing second end, and a shell fin adjacent said open first end projecting radially outwardly from said side wall;
- a drum head having a top hoop and a membrane positionable across said open first end of said drum shell and substantially enclosing said open first end, said drum head supportable by a surface adjacent said first end of said drum shell and affixable to said drum shell by said top hoop, said top hoop having a plurality of top hoop attachment areas;
- a bottom hoop dimensioned to substantially surround an outer perimeter of the drum shell and slidably engageable therewith to slide over said second end of said drum shell opposite said open first end, said bottom hoop is spaced away from said second end of said drum shell towards said open first end in an abutting position with said shell fin;
- wherein said bottom hoop is removably attachable to said top hoop by attachment members;
- wherein said bottom hoop includes a leg having an inner surface, and said bottom hoop includes a plurality of bottom hoop attachment areas extending radially outwardly from said leg;
- when said bottom hoop is in said abutting position with said shell fin, said inner surface of said leg is in a 360 degree circumferential face-to-face relationship with an outer surface of said side wall of said drum shell, wherein said outer surface of said drum shell side wall has a first diameter and said inner surface of said leg has a second diameter, and wherein said second diameter is smaller than said first diameter to compress said side wall of the drum shell;
- and
- wherein each of said bottom hoop attachment areas is substantially alignable with at least one of said plurality of top hoop attachment areas.

In a drum of the class wherein a drum shell is formed from a bucket, comprising:
- wherein the drum includes a drum head having a membrane and a top hoop having a first inner diameter, said top hoop tunably attachable to a bottom hoop with removable attachment members, wherein said bottom hoop is spaced away from a bottom end of said drum shell towards said top hoop, the combination with said bottom hoop of an annular vertical leg having an inner surface, and an adhesive, wherein said adhesive mates said inner surface of said annular vertical leg with an outer surface of said drum shell formed from a bucket, wherein said vertical leg includes a second inner diameter that is smaller than said first inner diameter of said top hoop, and wherein said bottom hoop includes a plurality of attachment areas extending radially from said vertical leg that are alignable with each of a plurality of top hoop attachment areas.
A bottom hoop for a drum formed from a 5-gallon bucket, comprising:
- an annular leg having an inner vertical surface mateable with an outer surface of a side wall of the 5-gallon bucket;
- a plurality of radially projecting attachment areas, each attachment area of said plurality of radially projecting attachment areas having a top lateral surface mateable with a bottom lip of a shell fin of the 5-gallon bucket;
- wherein each attachment area of said plurality of attachment areas is alignable with a respective top hoop attachment area of a top hoop, said top hoop being a part of a drum head including said top hoop and a membrane;
- and
- wherein said top hoop encircles a portion of said 5-gallon bucket above said shell fin and said vertical leg of the bottom hoop encircles a portion of said 5-gallon bucket below said shell fin and wherein the bottom hoop is spaced away from a bottom end of said 5-gallon bucket towards said top hoop, said shell fin interposed between said top hoop and the bottom hoop.
