One aspect of the invention concerns a method of manufacturing the body of a drum kit. The method includes the steps of rolling a flat, unpainted metal sheet (10) to a cylindrical form (12) and welding free edges (14) of the form to produce a cylindrical body (18). This body is temporarily stiffened and paint is applied to the exterior of the temporarily stiffened body. Thereafter the body is destiffened before it is deformed to a suitable shape for nesting with other such bodies. Other aspects of the invention concern the apparatus used in the method and the drum kit itself, including the body and top and bottom ends which can be attached to the respective ends of the body. Yet another aspect of the invention concerns a drum kit body which is of tubular form, which is suitable for nesting with other similar bodies and which has a weld line running from one end of the body to the other. The exterior of the body, including the weld line, is covered by a continuous paint lining applied to the body by a roller spraying operation.

A method of manufacturing the body of a drum kit, the method including the steps of rolling a flat, unpainted metal sheet to a cylindrical form, welding free edges of the form to produce a cylindrical body, temporarily stiffening the cylindrical body, applying paint to the exterior of the temporarily stiffened body, and destiffening the body.
A drum body manufacturing and nesting method comprising the steps of:
A drum kit comprising a body manufactured by rolling a flat, unpainted metal sheet to a cylindrical form, welding free edges of the form to produce a cylindrical body, temporarily stiffening the cylindrical body, applying paint to the exterior of the temporarily stiffened body, and destiffening the body, a drum top attachable to an operatively upper end of the body and a drum bottom attachable to an operatively lower end of the body.
A drum body manufactured by the steps of rolling a flat, unpainted metal sheet to a cylindrical form, welding free edges of the form to produce a cylindrical body, temporarily stiffening the cylindrical body, applying paint to the exterior of the temporarily stiffened body, and destiffening the body.
A drum body of a drum kit, the drum body being of tubular form being suitable for nesting with other similar bodies and having a weld line running from one end of the body to the other, the exterior of the body, including the weld line, being covered by a continuous paint lining applied to the body by a roller spraying operation.
Apparatus for manufacturing the body of a drum kit, the apparatus comprising means for rolling a flat, unpainted metal sheet to a cylindrical form, means for welding free edges of the form to produce a cylindrical body, means for temporarily stiffening the cylindrical body, and means for applying paint to the exterior of the temporarily stiffened body.
Apparatus according to claim 28 including means for curing the internal coating and external paint.
