Tramming is done with a co-axial indicator. It is common that many
Bridgeport clone mills are made with a slight tilt where the front of the
table is slightly higher than the back. This is done so that when the mill
wears in a bit, it will be square. This slight upward tilt will also
partially compensate for work loading on the table. In any case, it usually
doesn't matter.

Just Brits? Heck, for us Americans, what is tramming?
The 'art' of adjusting the spindle truly square with the X/Y axis of the
table.
