Speaking of big Yankee drivers, in the early seventies I was working with an
almost-retired finish carpenter named Joe Shingle, born in 1900.  I watched him
hanging doors with one of the giant ones - in and out and in and out, I was
mesmerized.  That weekend I bought a used one at a flea market and showed up
Monday morning ready to hang doors.  First screw, the bit jumped the slot and
put a gouge in the door.  He said “you didn't get one with a spring in it did
you?”  Of course I had because I didn't know anything about these tools.  He
opened it and took the spring out for me and all was well with the world.
