On Friday I was trying to put a wire into an attic by drilling a hole in a finished wall. Well, the apprentice couldn't find the drill bit. I tried shaking, spinning, and tapping the drill bit for about 15 minutes. He indicated that it wasn't up far enough. Against my intuition I drilled a little farther and what do you know.....the bit went through the roof! The apprentice still didn't see the bit or shaft. I went up to help and saw it readily. Affecting perfect control; I pointed it out and we put the wire through. The new wire was installed so we could put up the ceiling fan. While cleaning up we happened to notice a loose shingle in the insulation, just one. One shingle, lost long ago in the insulation, just what we needed to repair the hole in the roof.
Wow, we pulled a rabbit out of our hat!
