Is there a easy way to tram a Post Style Mill?
All you need to concern yourself with is getting the left side of the vice jaw to read the same as the right side of the vice jaw. If your indicator varies a little bit going across the center portion of the jaw that is not unusual. Vice jaws are not all 100% flat. You just don't want a steady increase or decrease in your reading from one side to the other.
The only time that "swiveling" the head of the mill would be a concern is if you change the height of the head between operations on the same part. For example if you drill a hole in a piece of material, and then find you don't have enough space to insert a reamer to finish the hole. So you raise the head of the mill to install the longer reamer. If the head pivots slightly while raising the head (and you don't notice it) you are no longer in line with the hole you started. If you are lucky and catch it, you would need to re-locate the center of your hole again.
Like Tom sez - it doesn't really matter which way the head is pointing as long as you can reach every point of your material you need to get to.
