Musical drum precision tuning tool

A precision tuning tool for use in tuning a tunable lug rotatably mounted on a musical drum, said precision tuning tool comprising:

• (a) an elongated handle having a central longitudinal axis and including a front tubular shaft and a rear tubular shaft, said rear tubular shaft having a front end telescopically fitted over a rear end of said front tubular shaft such that said front and rear tubular shafts extend coaxially along said longitudinal axis of said handle, said front and rear tubular shafts being movable both axially and circumferentially relative to one another along and about said longitudinal axis;
• (b) a torque applying mechanism engagable with a tunable lug rotatably mounted on a drum, said torque applying mechanism being operable to apply torque to the lug so as to tune the lug by pivoting said elongated handle relative thereto;
• (c) a torque calibrating mechanism mounted to said elongated handle and being operable to define a desired preset amount of torque to be applied to the lug by said torque applying mechanism, said torque calibrating mechanism including a plurality of calibrated settings defined on said front tubular shaft adjacent to said rear end thereof and a latching device pivotally mounted on said front end of said rear tubular shaft and having a latch element releasably engageable with a selected one of said plurality of calibrated settings on said front tubular shaft to preset said desired amount of torque to be applied to the lug by said torque applying mechanism;
• (d) a preset torque indicating mechanism mounted to said front tubular shaft and supporting said torque applying mechanism adjacent to a front end of said front tubular shaft and, in response to application of torque to the lug by said torque applying mechanism, being operable to produce an indication when said preset amount of torque has been applied to the lug by said torque applying mechanism;
• and
• (e) a biasing mechanism mounted to said rear tubular shaft and being operable to apply a desired preset level of biasing force to said preset torque indicating means, in response to the defining of said desired preset amount of torque by rotating said rear tubular shaft and said latching device therewith about said longitudinal axis of said elongated handle to bring said latch element into engagement with said selected one of said plurality of calibrated settings on said front tubular shaft to thereby preset said desired amount of torque to be applied to the lug by said torque applying mechanism before said indication is produced by said preset torque indicating mechanism.
