Abstract:
1. A method for assembling components of a structure with fasteners, wherein said structure has an outboard side and an inboard side and a preexisting supporting frame for said components, said method comprising the steps of: providing a first component of said structure; providing a second component of said structure; placing portions of said first and second components together on said frame for providing a combined fastener receiving zone for each of said components; providing an electromagnet having a magnetizable core on said electromagnet, said core having multiple openings passing therethrough; positioning said electromagnet against said fastener receiving zone on said outboard side while positioning said openings at a substantially normal position against said zone; positioning a magnetically attractive member against said inboard side of said zone; aligning said electromagnet on the outboard side with said magnetically attractive member on said inboard side; activating said electromagnet for attracting said electromagnet towards said magnetically attractive member for holding said components together along said zone; providing multiple drill members for passage into said openings in said core; drilling a first set of multiple holes with said drill members substantially simultaneously in said zone and drilling a second set of multiple holes with said drill members substantially simultaneously in said zone, the first set of multiple holes being laterally offset from the second set of multiple holes; subsequently placing multiple fasteners substantially simultaneously into said multiple holes of the first set and subsequently placing multiple fasteners substantially simultaneously into said multiple holes of the second set; and subsequently driving said multiple fasteners substantially simultaneously through said multiple holes of the first set in said zone, and subsequently driving said multiple fasteners substantially simultaneously through said multiple holes of the second set in said zone; wherein said magnetically attractive member has an inner side and an outer side; and wherein said multiple fasteners are rivets and said method further comprising the step of mounting at least one bucking bar on said inner side of said magnetically attractive member, and wherein the at least one bucking bar is elongate and extends along a majority of the width of said magnetically attractive member to simultaneously overlay a respective hole of the first set of multiple holes and a respective hole of the second set of multiple holes.
