Hi John
I have followed your advice and made myself the tramming tool, and have to agree with you about how wonderfully easy it is to use, so now my mill table is as near as dammit spot on. I then tried the tramming tool on the bottom of my Vertex K4 vice, and found it to be out by about 6 thou, have you got any advice on the best way to try and true up the vice to the mill table
When I worked grown up machinery for a living, "my" machine was also used/ abused by others, on different shifts. Occasionally I had to deburr the table, and the bases of the mating jigs/ fixtures etc.
Afterwards, I always seated the vices to the table, with the fixed, hard jaw pad removed.
Then I took "a couple of thou", from the fixed jaw face and the top of the base, using a 2 or 3" dia endmill. Thus ensuring all was square and true to the machine spindle......
