One touch drum tuning components
Abstract:
Methods and devices for attaching a one touch tuning system to different drum types. Components preferably include a retrofit ring for fitting the one touch tuning system to a lug style drum, and elevators to attach and adjust the height of the tuning system on the drum. On full floating drums, a framework is provided so that no hardware need be attached to the drum's shell. Framework may also include adjustable pull rods which can attach a tuning system on one end of the drum to another tuning system on the opposite end. Twisting the adjustable pull rods one direction extends the length of them, twisting the opposite direction retracts them thereby shortening the overall length of the framework in relation to the depth of the drum shell. Offset rim rollers help align the inner hoop and rotating actuator rings to offer more precise tuning and free movement.
