I can see how this tool would be very useful, but with all this experience have you seen any elongation of the bushing in the spar? If I understand how this works, it applies a concentrated load where the smaller diameter of the tool contacts the larger diameter of the bushing. The tool is hard and the bushing is relatively soft? How is this tool not a reamer? http://en.wikipedia.org/wiki/Reamer

The one I use is machined out of a hard plastic - I think nylon. Works great.
