Abstract: A semi automated hole punch translates a punch and die assembly across the end of an H beam or the like to punch each of a plurality of holes in accordance with an interchangeable template. The punch and die assembly travel across the H beam in response to operation of a power source until a manually operated pivotable arm supporting a pin is brought into engagement with a hole in a template. Upon engagement, the translatory movement of the punch and die assembly ceases and an operator can actuate the punch. Upon lifting the handle to disengage the pin, translatory movement of the punch and die assembly will continue until the pin becomes engaged with a succeeding hole in the template.
