The apparatus comprises a support frame and a sliding head assembly mounted on the support frame. The sliding head assembly includes a chime ring retaining member. A drum support assembly is also mounted on the support frame and includes a first and second drum retention means. The first drum retention means prevent movement of the drum during positioning of the chime ring member while the second drum retention means guides the concentric expansion of the top portion of the drum. Means are also provided for actuating movement of the sliding head assembly as well as a source of power for supplying energy to the sliding head assembly.
