lol, difficult jobs make for a break in the tedium of "jobs I dont want to do" and provide a challenge. I find using a right angled engineers scriber useful for breaking (fatiguing) the threads out once you get to the point that your drill is at a point where you are starting to contact the wanted metal. A long and labouious task but can be ameliorated by the application of frequent alcohol (but not at the initial drill stage)
