At work, we cut a 6" hole in the wall for a duct. Later we decided we now want a 10 inch duct in the same place. what tricks are there to center the larger hole over the center of the smaller hole if it is already cut? I'm using a hand saw to cut into dry wall.

you can take a scrap piece of wood (maybe a scrap piece of drywall might work) and use the 10" hole saw to make a hole in the scrap piece (this will be you're "Guide"). Then center the "Guide" onto your wall and use the 10" hole as a guide for the hole saw to keep it centered. It might be easier with two people, one holding the Guide and the other using the drill.
you can see what I'm trying to say at around the 4:30 mark of
this video.
