A wood boring operation aid includes bore-locating templates, translation-control cross shafts, a bore-locating block, a boring guide sleeve, a peg, mounting blocks, and locking screws assembled together for mounting on a workpiece to make bores. The boring guide sleeve is externally threaded for screwing into a threaded hole on the bore-locating block without the risk of loosening from the bore-locating block during the boring operation. The translation-control cross shafts are provided with measuring marks, which could be observed via through screw holes provided near two longitudinal ends of the bore-locating templates to determine the new positions of the bore-locating templates translated along the translation-control cross shafts. And, holes provided along the bore-locating templates for locating positions for boring are sequentially numbered to enable quick and correct insertion of a peg into a desired hole.
