Abstract
A compact assembly for aligning a coring tool relative to a pipe sidewall. The coring tool includes a hollow, cylindrical hole saw mounted to an arbor that has an elongated pilot shaft centered in the hole saw. The assembly is made up of a base plate that is attachable to the pipe sidewall. In one embodiment, a tubular sleeve is mounted to the base plate and has a bore diameter sized for receiving the pilot shaft as the hole saw is advanced toward and saws through the pipe wall, and the entire assembly is sized to fit inside the hole saw as the hole saw saws through the pipe sidewall. In another embodiment, the base plate is configured for use with pipe sidewalls that include outwardly protruding ribs.
