I have a 1960 Bridgeport J head mill I am working on and have a
question. On the right side of the knee (facing the machine) there are
three 3/8-16 tapped holes, which are also spotfaced to accept washers.
What are these holes for? These are not the grease fitting holes, mine
hase nothing there. Just wondering if anyone knows what should be
there.
Thank you,
Craig
