Coring tool alignment assembly

A system for aligning a coring tool relative to a pipe sidewall, wherein the pipe sidewall includes ribs protruding outwardly therefrom, the system comprising:

• a hollow, cylindrical hole saw mounted to an arbor that has an elongated pilot shaft centered in the hole saw;
• a base plate attachable to the pipe sidewall, wherein the base plate includes a first terminal end having a first planar surface and a second terminal end having a second planar surface, wherein the first planar surface and the second planar surface of the base plate are configured to contact the ribs of the pipe sidewall, wherein the base plate includes a first side and a second side opposite the first side, wherein a first single foot extends along the first side of the base plate, and a second single foot extends along the second side of the base plate, wherein the first planar surface extends between a first end of the first single foot and a first end of the second single foot, and the second planar surface extends between a second end of the first single foot and a second end of the second single foot;
• a sleeve aperture through the base plate and having a bore diameter sized such that it receives the pilot shaft as the hole saw is advanced toward and saws through the pipe sidewall;
• wherein the plate is sized to fit inside the hole saw as the hole saw saws through the pipe sidewall.

• a base plate attachable to the pipe sidewall and including a first terminal end having a first planar surface, a second terminal end having a second planar surface opposite the first terminal end, and spaced apart peripheral feet protruding from an underside of the base plate to contact the pipe sidewall, wherein each foot extends from the first planar surface to the second planar surface, wherein the first planar surface extends between a first end of a first foot and a first end of a second foot, and the second planar surface extends between a second end of the first foot and a second end of the second foot;
• a sleeve aperture through the base plate and having a bore diameter sized such that it receives the pilot shaft as the hole saw is advanced toward and saws through the pipe sidewall;
• wherein the peripheral feet protrude by an amount sufficient to provide a clearance gap between the spaced apart feet to receive a curved sidewall of the pipe.
