Now I needed measurement to ensure everything will be modified correctly for full functionality. With a caliper I measured the thickness of the broken file end to compare to the thickness of the lock picks. In my case; the file piece and 3 picks were the exact same thickness. I used a drill bits outer diameter measurement to determine the size of hole I would require to drill in the pick handles . In image 6 I am sliding the picks into the handle void to see just how far I can go before hindering the sliding pliers function. Once I determined how far I simply used a Sharpy marker to draw a line at the base. Also note that I marked where the holes will have to be drilled on the green tape that I put around all 3 picks.
