A caliper apparatus, comprising,
- a first leg member pivotally mounted relative to a second leg member in a scissor-like orientation, with the first leg member and the second leg member including a pivot axle orthogonally directed through the first leg member and the second leg member pivotally mounting the first leg member relative to the second leg member, and
- the first leg member including a C-shaped first arcuate lower leg, with the second leg member including a C-shaped second arcuate lower leg, the C-shaped first arcuate lower leg includes a first concave side wall in confronting relationship relative to a second concave side wall of the C-shaped second arcuate lower leg, the first lower leg includes a first leg lower distal end radially spaced from the pivot axle a predetermined spacing , with the C-shaped second arcuate lower leg including a second leg distal end spaced from the pivot axle said predetermined spacing, and
- the first leg member further including a first leg extension leg extending above the pivot axle, with the first leg extension leg including an extension leg arcuate plate mounted laterally of the first leg extension leg concentric about the pivot axle, with the extension leg arcuate plate including an arcuate plate top surface, the arcuate plate top surface including gradations imparted thereon, and
- the second leg member includes a second leg indicator leg integrally formed relative to the second arcuate lower leg, with the second leg indicator leg spaced above the pivot axle, with the second leg indicator leg including a pointed free end positioned above the arcuate plate top surface, and
- the first leg extension leg includes a bifurcated head extending above the extension leg arcuate plate, the bifurcated head includes a first flange parallel to a second flange, and the first leg member includes a first leg stub plate, the second leg member includes a second leg stub plate, with the first leg stub plate and the second leg stub plate oriented below the pivot axle, and the C-shaped first arcuate lower leg includes a first leg sleeve at an upper distal end of the C-shaped first leg arcuate lower leg spaced from the first leg lower distal end, and the C-shaped second arcuate leg includes a second leg sleeve formed to an upper distal end of the C-shaped arcuate lower leg spaced from the second leg lower distal end, with the first leg sleeve arranged for receiving the first leg stub plate, the second leg sleeve arranged for receiving the second leg stub plate.
