Tramming - one of my least favourite tasks!
I would recommend using a dial indicator for that (it's the one with the plunger, not the swinging arm (Dial Test Indicator)) as the initial tram can be so badly off that you go off the end of your DTI, or spin it round the scale twice, which is very confusing as it doesn't count the whole revolutions, unlike the Dial Indicator.
You will also need a way to get your DI mounted such that you can spin it in your spindle and have it trace out a circle on your table.
