Abstract:
An adjustable fit laser-projecting reference tool comprising:a light beam means connected to a self-contained power source through an electrical circuit whereby said electrical circuit can be operated to closed or open said electrical circuit; and, a mounting means whereby said mounting means functions to attach said light beam means to any diameter of a cylindrical object; and, said mounting means functions to dispose said light beam means to project a light beam perpendicular to said cylindrical object's cross sectional plane within the outer diameter of said cylindrical object parallel to and including the longitudinal centerline axis of said cylindrical object; and, said mounting means functions to attach said light beam means to said cylindrical object and disposes said light beam means perpendicular to said cylindrical object's cross sectional plane within the outer diameter of said cylindrical object parallel to and including the longitudinal center axis of said cylindrical object; and, said mounting means disposes a top v-block and a bottom v-block to the outer surface of said cylindrical object wherein said top v-block and said bottom v-block are self-aligning so that said top v-block can be moved in a sliding fashion with respect to said bottom v-block by v-block guide rods disposed to maintain self parallel alignment between said top v-block and said bottom v-block; and, said top v-block and said bottom v-block surrounds said cylindrical object and sandwiches said cylindrical object urging said cylindrical object's centerline to the same plane as the centerline of said top v-block and said bottom v-block; and, said top v-block and said bottom v-block include a guide track for a slide scale assembly so that said slide scale assembly can be slidably disposed between said top v-block and said bottom v-block perpendicular to the longitudinal centerline of said cylindrical object when the adjustable fit laser-projecting reference tool is attached to said cylindrical object; and, a slide scale bracket to position said slide scale assembly as required by the user with said slide scale bracket being removable allowing said slide scale assembly to be interchangeable; and, said guide track allows said slide scale assembly to slide in a manner in which said slide scale assembly's center point has the ability to pass through the projected longitudinal centerline of said cylindrical object; and, a v-block clamping rod is held fixed to said bottom v-block and is allowed to slide through said top v-block with a clamping rod nut engaged on said v-block clamping rod disposed to urge said top v-block slidably towards said bottom v-block when said clamping rod nut is turned clockwise on said v-block clamping rod.
