Trying to remove the shaft that is inserted into the baseof my drill press. No lock screw, bots or any other fastner that I can see. It appears to be pressed into the base. I tried taping with a hammer and punch, no movement at all. Perhaps I am overlooking something. The picture is NOT my actual base but it looks just like this. Just to be clear, I am trying to remove the "shaft/pipe/pole" that is inserted to the base. Not the 4 bolts that bolts the coulumn onto the floor plate. Done that already. And yes I looked on the antique machinery forum.
