Check e bay for a machinist's tachometer. It is a little device that looks
like a large key. The "pointy" end has a little pyramid shaped tip that you
push into the drill or lathe chuck. This turns a dial that you have set to 0
and then you run it for a minute and check the reading. I know that Lufkin
made one.
