Segmented drums are made by stack laminating rings made of up of solid wood pieces.  Unlike traditionally manufactured drums the wood is not bent to shape, but turned on a lathe.  The resulting drum contains less glue, is not limited to the species of wood used my large manufacturers, and allows a wide range of shell thicknesses. p3290001 Constructing a shell is a slow process requiring many sessions of turning and gluing.  I usually use 12 sided rings cut on a tablesaw.  I glue them together with band clamps leaving one joint on each side dry resulting in a ring split in half.  Each of these halves is narrow enough to run through the planer to true up the surfaces.  I sometimes round out the halves on the bandsaw prior to finally gluing them together.   p3290006 These rings are then glued to a faceplate matching the final diameter of the drum and turned down close to the final dimensions. p3290002 p3290004


This process is repeated until the desired depth of the drum is reached.  The drum is sanded on the lathe and then parted from the faceplate. This is a somewhat scarry step.  It helps to have a variable speed lathe ruunning very slowly.  I usualy cut with the parting tool until a very thin layer of wood remains and then give it a nudge with my palm to break it free.  The splinters that break free from the inside would be removed when cutting the bearing edge anyway. The bearing edge is cut easily on the router table with a 45 degree bearing edge router bit.  I cut about 1/8″ in from the outside and cut the remainder from the inside.  The depth of cut will depend on the thickness of the shell. The drum is then drilled for hardware and if it is  a snare the beds must be cut.
