I learn something everyday. Sometimes I learn from the things I try by myself, and sometimes from what is suggested by others. Today's lesson involves a tool called a "transfer punch" which a fellow box maker suggested for marking the center of hinge holes for accurate drilling of pilot holes. The transfer punch set shown has punches far larger than I will ever use for making boxes, but the complete set cost only 9.95 at Harbor Freight and will last me a lifetime. You choose the punch that fits the hole, then tap it to mark for drilling.
Since marking and drilling pilot holes for teeny tiny screws is one of those things that can really bug a box maker, I expect this tool, acquired today, to make my box making even more fun.
