I've been asked many times to show the 3" post I cemented into the column on this mill...and to show the jacking bolt setup I use to aid in tramming this thing. The bolts also add stability to the lower base. Without them the base can actually flex. This whole affair ties it all together. It's ugly.. I did it in a hurry and grabbed whatever fit at the time. The big bolt in the bottom of the shaft goes right through and jacks against the base toward the front. You can figure the rest out I guess. Some of the stuff is welded on afterwards...way inside. More bracing to steady things.
Add this to the "Million Ways to Improve A Mill Drill" deal that everyone hates
