Dear WW: I finally remembered one of the situations in which one kind of "chatter marks"
were troublesome. My father bought a big machinist's metal working lathe because it had
gotten worn to much to do fine machine works. We made our own baseball bats on it.
It took a lot of practise to be able to hold chisels to remove wood smoothly. Held the
wrong way, they would dig in deeply, and then jump back, very rapidly, leaving a series
of mars that spoiled the look of the surface.
For Fourth of July, my father drilled out a large piece of truck axle, and made us a cannon
that you could hear for miles when we set it off down on the Common. The Hunt kids had
an admiring audience, I can assure you. Oh to be a kid again.
