ABSTRACT:
A tool comprising a turning bar, a pipe supporter, a handle to turn the pipe supporter and a turning disc to rotate the turning bar. The turning bar fits and rotates in the central hole in the pipe supporter and forces two steel balls to move outward in two opposite sidewise holes in the pipe supporter with the lower tapered portion thereof. Then then handle is moved to rotate the pipe supporter in relation to a pipe fitted around the pipe supporter, allowing the steel balls to compress outward the inner surface of the pipe to form a circumferential projection thereon.
