I had been dreading this day for a long time, but it worked out fine in the end. Today was the day I had to locate and drill the pilot holes for the Alternate Air and Oil Cooler control cables through the left gear tower. As I mentioned in a previous entry, the tower is full of wires and hoses, the fuel filter is on the front of the gear tower, and there are numerous other considerations such as pilot line-of-sight to consider when locating these controls. After one nearly big mistake, I recovered and managed to use a combination of a drill guide, an angle drill, a 12" bit, two work-lights, duct tape, mirrors, rulers, and some luck to drill the four holes. They will each be opened up to different sizes tomorrow, but for now I can sleep, knowing that the hard part is over!
