Model Railroad Hobbyist | September 2015 | #67 MRH Q-A-T column compiled by Joe Brugger Questions and Answers Drilling holes for grab irons Q. I have just spent the last two weeks trying to drill umpteen #79 holes for the grab irons on a Tichy USRA box car kit. Nine broken #79 drill bits later with some bit ends stuck in the hole I was drilling, I am totally frustrated. I have been using my fin- est twist drill, soaping drill bits and trying to keep the work as steady as possible. What’s the secret? —Ken Adams A. Geoff Bunza: Drilling tiny holes can be a challenge. Fortunately, soft plastic is about the easiest material to use, if you want to call it easy. I have never been able to use a motorized drill with #80 and #79 bits with consistent luck. I always use the smallest pin vise I have. Insert the drill bit as far into the pin vise as you can, leaving only enough exposed to make the correct depth hole. XX MRH QUESTIONS, ANSWERS, AND TIPS MRHMAG.COM • TABLE OF CONTENTS • INDEX
