ABSTRACT:
An alignment tool for adjustably positioning a boring bar relative to a spaced apart fixed location on a structural member including an elongated bar formed of a plurality of axially aligned and separable tubular members and having its opposite ends mounted to the boring bar and the fixed location, respectively. The length of the bar, hence the distance between the boring bar and the fixed location is adjustably selectable by means of telescopically mounted one of the tubular members. A first one of the tubular members receives therein a second one of the tubular members employing a thread interconnection whereby rotational movement of one tubular member relative to the other provides selection of the overall length of the tool. Multiple indicia associated with the outer circumference of each of the threadably interconnected tubular members provide a visual indication of the extent of the insertion of said second tubular member within said first tubular member, hence the overall length of the tool.
