I have a Series 1 Bridgeport mill I have been working on for some time. I am about to start enough of the re-assembly process that I really want to have it in place and as level as possible before I make it any heavier.
My concrete floor is imperfect as they typically are. Its not rough, but is not perfectly flat either....and likely the bottom of the mill base casting is not either. Up till now, I have used some steel shimming to level it, but with the four corners as contact points, you end up chasing it in circles and it is inexact at best. The real goal is to make it stable, but I have a precision level and I would like to be able to level it both directions.
There are 4 holes in the base and I have been thinking of ways to try to make some sort of levellers while I can still get under the thing to set them in place. The design does not make this easy as you really need to be adjusting a nut on the back side from the holes or a bolt protruding through the top side, and I was wondering if any of you knew of or could provide a picture of a commercial solution to this. I had been thinking of ways to accomplish this for some time and then was inspired when I saw the picture of something like this in this picture from a recent thread. Anyone done something like this and have a picture or diagram of just how they made the "feet" and made them adjustable from the top side?
Thanks in advance for any help you can offer!
