You can align the lens with something like the Delta 1 Bes-Align used with a laser alignment tool. As far as the column is concerned I would have to check to see how much that varies. I'm not sure but I stumbled across a thread somewhere where someone said aligning the negative and the lens was far more important than aligning the negative/lens to the baseboard. I don't know if that's true so don't quote me. Just a post I saw somewhere. I would have to research it or test it myself... not very inclined to do the latter. It would be good to know what the deal is though.
