Be sure when using the drum dial to place it on the head lined up directly with each tension rod. Use a Drum Dial (available from most major music and/or percussion retailers) that measures the head pressure at each tension point around the bowl.At this point, remove the block of wood from beneath the pedal! Next, using the same sequence but in smaller increments (1/2 turns), tension the head until it reaches the lowest note in the playing range (as suggested by the drums manufacturer).

After each rod receives one full revolution, repeat this procedure.

Following the cross lug sequence (pictured right), begin to apply tension with the timpani key by turning each rod 1 (one) complete revolution.

Replace the tension rods and finger-tighten them until they make contact with the hoop.

Place the new head on the bowl and replace the counterhoop, checking to insure the space between the hoop and the edge of the bowl are equal around the entire perimeter of the drum.

Teflon spray is available through percussion specialist retailers or hardware stores.

Lubricate the bearing edge by spraying a thin, even layer of Teflon spray along the entire bearing edge.

Line the counterhoop with adhesive felt, rubber, or moleskin to eliminate noises (buzzing) that occur from contact with the counterhoop and the head.If the Teflon tape is damaged or peeling, remove it before using steel wool on the bearing edge.) Remove dirt and old lubricant from the tension rods and apply fresh lubricant (lithium grease). (If your timpani already has Teflon tape on the bearing edge, and it is not damaged or peeling, then do not remove it or use steel wool on it. An extra-fine steel wool #0000 can be used to gently clean the bearing edge. Make sure that the bearing edge (lip) is smooth and clean at the point of contact for the head. Remove the old head and completely clean the entire bowl and support mechanism.Place a block of wood under the toe of the pedal to prevent it from snapping forward when the old head is removed.Please refer to the Evans Timpani Head Sizing Chart to determine which head size is correct for your timpani. Change timpani heads when the tone starts to sound dry or dead or the pitch becomes “false” meaning it is impossible to fine-tune the head and obtain a clear pitch.
