Good suggestion Terry. But don't take it for granted that it will be
free of run-out just because its a Jacobs. We have two of them at our
place, and one should be have been returned when it was purchased.
I'd recommend taking a dial gauge along to your supplier and checking
it in a drill with a piece of round ground stock as a test piece.
Even some of the Chinese stuff is testing straight these days, but
sometimes they fail because the heat treating isn't.
