I had to reconsider the 4" box tubing, under the mill, while raising the mill up, it also gave me some leveling issues. After about 1-2 hours of shimming and cursing, I decided to add leveling feet to the mill.
So last night, I installed some leveling feet (from a source I can not remember) under the front cross brace and a some tubing of the same height, under the back, it was a lot better, but because of the floor condition, there was still some shimming needed.
This morning I ventured out to the industrial supplier, and picked up some hardware to manufacture some back leveling feet.
2 - 4-1/2" of 1-1/4" B-7 Hardened all-thread
4 - 1-1/4"-7 2H heavy nuts
4 - 1-1/4"-7 jam nuts
2 - 1-1/8" flat washers
2 - 1-5/8" flat washers
4 - 1"-8 2H heavy nuts
4 - 1"-8 jam nuts
Welded a 1-1/4" 2H heavy nut and a 1-5/8" flat washer on the end the 2 pieces of all-thread. I then after the welding, put the pieces in the lathe and cut the bottoms of the piece, flat. Then assembled them, the welded piece, a jam nut and a flat washer.
Using the Jet toe-jack, lifted the back of the mill, removed the back cross tube, drilled 2, 1-1/4" holes in the bottom of the tube. The using the fabbed piece, put a 1-1/4" 2H nut inside the tube clamping the nut down tight and then welded it in place. After it cooled down, installed both fabbed feet in the box tubing and reinstalled it in the mill.
I went to the front of the mill, raised it up and removed the front cross tube. Removed the acquired leveling feet, with 1"-8 thread, then welded 2 of the 1" 2H heavy nuts inside the tube, making the leveling procedure easier. Reassembled the front leveling feet and the cross tube assembly and reinstalled it under the mill.
Then leveled the mill, side to side and front to back, it is now level, and rock solid, this added an addition 2" to the height of the mill, putting the bottom of the quill at 59" off the floor, but with the ER32 x R8 collet chuck, thats on the UPS truck for delivery, today, with stick out ~2" from the bottom of the quill, bringing it back down to about 56"-57", which I think is just about right.

4 - ready to go under
