Ok, so LEVEL as we know is a relative thing.
TWIST is the thing to be concerned with right.
I spent some time with a Starett #98 and some shims and have things dialed in as far as the level bubble indicators go front to back at both ends.
NOTES:
It is NOT Bolted to the floor.
The original Atlas legs are mounted to 3" Angle Iron with Castors (but I have them locked in position so it hasn't moved that I can tell)
Now for my (2) Questions:
With what started as a 1" diameter Rod with 3" inside the chuck jaws and 4-1/2" unsupported I have approx .003 of taper over 4".
(it was much --much worse when I started).
Should I continue to chase it down or is that pretty good?
Or is the .003 just tool deflection over the 4" of unsupported stock?
If I check the Lathe Ways end to end both ends I find there seems to be a BOW in the bed as the Left (Tailstock End is (3) Bubble increments lower than the Ways measure End to End near the head stock.
I found an old Atlas leveling document that says the Ways should be leveled end to end is that where my .003 taper comes from?
It shows measuring and leveling out both front to back and end to end - see attached PDF.
