Weaver's Delight Harness Slide Fix

This is my quick fix for the worn in groove in the cast part, Bracket harness slide 103 L.  The part can be replaced, but the cost is around $30.  Right now, I would rather spend that money on some rug warp. Instead, I took a finish nail that fit into the groove, and bent it until it would grip tightly.  The groove to the left of it also needs one, but that one wasn't binding the shaft.  I know where to find another nail if it becomes a problem.
