ABSTRACT:
A replacement metal cap clinching tool for recapping automobile door and trunk lock cylinders. The tool has a base, that may be mounted in a bench vice, having a cap receiving pocket that has a resiliently compressible rubber cushion seated in the bottom thereof and upon which replacement metal cap is placed that receives the head end of a lock cylinder that is to be recapped. Two opposing handles that are each pivotal pin mounted in the tool base, are each formed with an inwardly directed clinching nose that engage respective opposite side cap tabs aligned therewith that are first bent inwardly by the handle clinching noses that translate with continued handle inward rotation to a semi-vertical action with final crimping action of tabs with force reaction through the lock cylinder and the cap resiliently compressing the rubber cushion in the tool. With each cap having two sets of equally spaced opposite side tabs after the first set of tabs on a replacement lock cap is clinched the clinching handles are retracted and lock and cap are rotated ninety degrees and the manual crimping process is repeated.
