Once in a while an old memory from my work days pops into my head. One day I saw my boss up on a ladder drilling a hole in an I-beam in order to mount a hoist.
I walked by again and he was still there making no progress. When he saw me he asked. "How the hell do you drill a hole?"
He was starting out with a 3/4" bit !
What a freaking idiot. I told him to start small and make increasingly larger holes.
Now 30 years later, I'm wondering if he ever had to use a hole saw. :)
