Looks like a good machine. There are days when I wish my 1440 was a 1425.
No worries here! You didn't hurt my feelings. Lol
So you want to verify the headstock is accurately positioned?
correct I don't have a great way to measure the exact difference but from a comparative standpoint its the same height from the flat to the prismatic. indicator less than .0005 of variance along the length of either of the ways. Indicating say the back flat to the top of the back prismatic then to the front prismatic distinctly the front prismatic is taller by more than the measurement of my dial indicator. The carriage rides on the front prismatic and rear flat way, and the tailstock on the front flat and rear prismatic way. So i ended up doing my comparisons using 123 blocks as the two flat ways were on the same plane but threw me for a loop for awhile trying to do anything with a level off of the prismatic ways.Your front and rear prismatic ways are not the same height, correct?
ha ha, you are no doubt right some of it is I have absolutely no clue of what is normal aside of trying to match what the test accuracy is in the original test certification sheet from the factory from 1883NASA just called and said your parts are within tolerance so nothing to worry about

Seems like you're trying to work ahead. Just take one problem and address it. Set the lathe up where and how you want it. I doubt you need to fortify the stand. But after that's done, worry about fixing bed twist. After that's done, worry about headstock alignment. Take smaller bites. Yeah?That was my goal or intent so then its safe to assume or adjust anything else based on bed or twist or the stand if I need too
and to verify or dial in the headstock i need to prove or ellimate twist from the bed/ways was my understanding
