This morning I saw a very strange method of tramming a vise, to the mill spindle. It took the guy about 30 seconds and bang he was done. I asked about it, he said he sometimes removes the vise 10-15 times a week and this method makes it almost painless.
He puts the vise on the table, slightly tightens both bolts, he has a ball bearing on a shaft that goes into the quill, he starts at the middle of the vise, moves the table about an inch in one direction, the an inch, in the other. Then repeats the process, between 2" and 3" movements, right and left, then finish tightening the vise to the table.
I questioned his procedure, he took out an indicator, ran it across the face of the vise, the needle barely quivered, way less than .001".
I have not done this myself, I just this morning saw it done for the first time, but it did look interesting. I may have to try it out, to see if I get the same results.
