    I would remove the keys temporarily, and apply prussian blue to the tool holder. Place the tool holder into spindle and twist slightly to show if there are any high spots or other problems that would require re-grinding the spindle.

    Have you set the locking nut up as described in the Bridgeport manual?

    You can't tighten them by hand. You need to use a spanner wrench.
