I am in the process of a CNC conversion, and was attempting to reassemble the G0704 mill table. However, the gib will only go in about 3/4 of the way. It was put back in from right to left while facing the machine. I have never had it removed, and the table moved freely in the past under manual operation. The gib measures .288" on the thicker end and .220" on the thinner end. Any suggestions?
