Mass proportion scaling apparatus

An apparatus for measuring a swing mass moment of a sports' implement, comprising:

• a support base having a horizontal portion and a vertical portion extending upwardly from said horizontal portion;
• an arm having opposed ends and a pair of grips coupled to said opposed ends, respectively, said pair of grips being configured to receive a first portion of the sports' implement;
• wherein said arm includes a beam pivotally coupling said arm to said vertical portion of said base, said beam being configured to pivot according to a gravitational torque of the sports' implement about the arm;
• a calibrated counter force element coupled to said arm between said support base and said beam and that is configured to apply an automatically increasing amount of counter force against an increase in angular rotation that is applied to said arm;
• wherein said calibrated counterforce element is movable between a first unloaded configuration before the sports' implement is received by said pair of grips and a second loaded configuration after the sports' implement is received by said pair of grips;
• a scale positioned on said vertical portion of said base and having a plurality of reading indicators indicative of measurements of a dynamic swinging mass of the sports implement using static assessment criteria;
• and
• a scale indicator coupled to said arm and mechanically connected to said scale and configured to mechanically indicate a respective reading indicator associated with a static angle of said arm.
