ABSTRACT:
The present invention relates to a hand held rivet bucking tool having a vibration dampening assembly including a visco-elastic polymer. The bucking tool features a dolly disposed within a housing and a vibration dampening assembly disposed therebetween. The visco-elastic polymer portion of the vibration dampening assembly absorbs and dissipates the vibration energy resulting from impacts received and delivered by the dolly. A second embodiment of the invention features a quick change dolly which can readily be removed from the housing so that a particular dolly can be used in conjunction with a particular rivet to be installed.
