Abstract
Abstract An easily attachable shaft aligning device comprised with a gauge supporting post that will support dial indicators that make contact with the second shaft to be aligned. This indicator holder has a metal base which houses two levers with hooks on their outer ends that receive any selected link of a chain that encircles the shaft to be aligned by screwing the dial indicator support post into the metal base against an inner part of the levers lifting the outer hooked ends of the lever and thereby tightening the chain to said shaft.
