The 1st & 2nd pictures show the crank end of the spindle & tailstock how showing how far out of parallel it is to the lathe bed. I lined up the chuck end of jig with the head stock in picture 3.This is mine showing head stock & tail stock alignment in 4th picture. I am not sure if the pictures will come through as I am new here & don't have some permissions yet.

Not tto bad… But if you want it closer, you should be able to get a better alignment on most lathes by adjusting the front left leg leveler (tailstock end). I check and adjust every time the lathe is moved. The beds on most lathes will twist if the floor is the least bit uneven.
