Anyways, if I am understanding what you are doing and have done, looking at the picture, the tail stock is not there. Any shims put under the tail stock at feet?? Will lift, angle, and or tilt the tail stock in relation to the head stock bore centre line.
Have you levelled the lathe/bed? Is lathe sitting on a firm surface? Please do not move the adjustment screws under the head stock, not for awhile yet.
Start by putting lathe firm surface, level six ways from sunday with a fairly accurate level, I start length wise, then do across the bed as close to head stock as I can, remove chuck if need be. Don't try to get everything prefect at each spot, as often levelling one place will move others. Move tail stock towards head stock, so can put level across bed to level end, take a look at where bed feet/ mount is, try to get level over this area.
Now sit down, take a moment to wonder how long it takes Bandit to tell a story. Any way, keep doing this until lathe is as level as you can make it. If you haven't given up yet, now get out the real accurate level and do it all again.
Some times there will be a slight twist in the bed or a low spot length wise on the bed, don't get super angry yet, it can take a bit of time for machinery to settle in place, a day a week, or ?? This can be related to temputures, what it sitting on, vibration from the train going by and so on.
If you are familiar with all this, good, have a thought about what you want to make. Parts for cultivators , or parts for the latest greatest million rpm turbine. The accuracy needed should be related to what is needed to do the best work for the job. Unless you want super, super no matter what.
