Yep, you could slice them from pipe, BUT... I have found that the slicing
process tends to make them somewhat "egg" shaped in cross section, either
from the blade pressure or from the clamp holding the pipe you are sawing. 
At least the F-F sweat couplings are round.

In any event, make yourself a wide feeler gage from shim stock of the
appropriate thickness to align them.  Then, run the gap across the NST
(without caps or primary) and look where the sparks occur.  If the gap is
uneven, the sparks will tend to clump at one end or the other.
