Mandrel assembly and method of using the same

A mandrel assembly has a mandrel, a biasing member, and a outer member. The biasing member biasly maintains the outer member in a first position, which corresponds to a contoured portion of the mandrel, when the outer member is either on the access or the blind side of a workpiece. The biasing membe...

description A mandrel assembly has a mandrel, a biasing member, and a outer member. The biasing member biasly maintains the outer member in a first position, which corresponds to a contoured portion of the mandrel, when the outer member is either on the access or the blind side of a workpiece. The biasing member is compressible to allow the outer member to move into a second position as the outer member is moved through an opening in the workpiece. In the first position, the outer member includes a maximum outer circumference that is larger than the opening of the structural workpiece. In the second position, the outer member includes a maximum outer circumference that fits within the opening of the structural workpiece.
