Got the granite table in place, bit of pushing with the tractor, some with a pry bar. This puts all of the large machines (>5,000lb) where I think I want them, but I'm leaving them on 4x4's for a day or two before setting everything on leveling pads, give me a little time to decide if it feels right. The lathe bed is not quite parallel to the back wall, it angle in a bit at the tailstock end, but I think it'll work best that way as the headstock has the lathe electrical cabinet behind it. I left a bit more than 3' behind the lathe, easy to walk behind it, and I'll probably put shelves on the wall to store various things (primarily lathe and mill related things). The three phase electrical still needs several days of work to be functional.
One idea from Abom79, the mill table, if moved all the way to the left, would be in the right position to put a steady rest on for something longer than the lathe bed.
