Lawn mower reel assembly measuring system

A lawn mower reel assembly measuring system for determining the taper in a reel assembly of a lawn mower comprising, in combination:

• a flexible tape fabricated of an essentially inextensible material and having a short leading edge and a short parallel trailing edge and with long parallel side edges there between including a first side edge and a second edge, the first side edge being linear along its entire length and devoid of markings, the tape having a front face and a rear face;
• a magnet secured to the tape adjacent to the leading edge and adapted to be releasably secured to one face of a blade of a reel type lawn mower whereby the remainder of the tape may be wrapped around the reel assembly for determining the approximate circumference and diameter of the reel assembly of a lawn mower;
• indicia on the front face including equally spaced major markings along the majority of the second side edge with about 3.1416 inches between the major markings and with equally spaced minor markings at every tenth of an inch between the major markings and with miniature markings every fortieth of an inch between the minor markings;
• a vernier scale extending laterally offset from the second side edge of the tape adjacent to the leading edge with equally spaced primary vernier markings at about 0.000, 0.005, 0.010, 0.015, 0.020, and 0.025 of an inch with four equally spaced supplemental vernier markings between each primary vernier marking, the 0.000 marking being offset from the 4.29 location of the front face and the 0.025 marking being offset from the 4.89 marking of the front face;
• whereby the tape may be wrapped around the blades of a reel assembly of a reel type lawn mower to determine its diameter and through wrapping and measuring at different locations of the reel assembly, the taper of the blades may be determined to assist in proper grinding.
