Abstract
A tool for facilitating threading of a flexible filament or sheet into a hole or opening. The tool includes (i) a filament or sheet guide having a longitudinally extending trough, and (2) an alignment system with (A) a first registration surface configured and arranged to transversely align a hole in a target-piece with the trough when the target-piece abuts the first registration surface, and (B) a second registration surface configured and arranged to laterally align a hole in a target-piece with the trough when the target-piece abuts the second registration surface. Threading of the filament or sheet into the hole or opening can then be achieved by simply causing an upward deflection of a distal portion of the flexible filament or sheet within the trough and moving the deflected distal portion of the filament or sheet along the length of the trough towards the aligned hole or opening in the target-piece until the distal end portion enters the hole or opening.
