Description
In the early days, even in well made sets of pin teeth, there was a wide variation in the spacing of the pins. To make a metal plate it was necessary to mark pin positions with paint on one pin, punch a single hole, fit one pin and mark and punch the other. Here the taper reamer was used to enlarge holes to avoid a too tight fit. Young's pliers solved these problems by producing two holes in exactly the desired position.
