Abstract
A method of boring a plurality of aligned, mating bolt holes in a pair of separated coupling flanges comprising the steps of: PA1 a) providing a template with pre-formed holes matching a desired location for bolt holes in the pair of coupling flanges; PA1 b) securing the template to a first of the pair of coupling flanges; PA1 c) attaching a boring tool to the template in alignment with one of the bolt holes; PA1 d) re-boring one of the bolt holes in the first coupling flange and repeating steps c) and d) for each remaining bolt hole individually in succession; PA1 e) removing the boring tool and template from the first coupling flange; PA1 f) relocating the template on the second of the pair of coupling flanges; and PA1 g) repeating steps b) through e) for the bolt holes in the second coupling flange.
