An apparatus for adapting the size of a drum comprises a cylindrical body extending between first and second ends and having a central passage therethrough, the first end defining a first opening adapted to receive a first drum therein and the second end defining a second opening adapted to receive a second drum therein. A method for adapting the size of a drum comprises locating an input drum within a first opening through the first end and locating an output drum within a first opening through the second end. The input and output drums may have one face removed therefrom exposing an open end for insertion into the apparatus. |
