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. |
