Care to elaborate?
I did search on several words in knee/mill/aligment and I can find plenty on tramming, but tramming I can do. I'm missing information on knee/table aligment methology. I have dreamed up something, but before trying my luck on something weigting several hundred kilos.
I think I need to start from column guides on, see that they are straight
I have two avenues:
1) Could borrow a engineers framed level and work from that on.
2) Foreget leveling it perfectly, and use something else to square it. Engineeing square forexample, just to see biggest shortcoming.
It's Sunday, I'm comparing some 500-600 mm long paralles to know straight edge and squares. Paralles are stright to my purpose, but only smallest square is trully square to grade#1, DIN something and Mitutoyo I trust.
Monday I could shop something or get a Friend to get me out of trouble. But today I'm cross checcking sqares until I have someting to get intila impression that is the table just drooping a little on it's nose or also every and each way.
* Little update: Preliminary test shows that table is a little nose up and column rail is pretty straight. Table seems to be quite a bit inclined lenghtways, left (heavier side) down. Therefore I checkked if the weight makes it rock and it does 0,05 mm / 500 mm distance- Least gibs are tight. I have to clock remainin axis and see that nothing is simply not loose.
There is no obivious easy adjustment to correct that tilt, I want to make sure I'm doing the right thing.
