Drilling Jig

by sheltech on February 7, 2011

this is a specialized drilling jig for drilling 1.15mm holes in the center of a stack of 8mm circles . the vise grips have been modified by drilling clearance holes in both jaws. also, a bushing plate has been soldered to the upper jaw ; this plate fits exactly into the space in the aluminum base plate ,both locking down the stack of parts and providing the drill bit with accurate location and guidance. the bottom shot shows the vise grips clamping down a stack, ready for drilling.
