Corner??? I'm thinking starting in the middle and working my way to
the outsides. Altho if its jacked up with 2x4s, where I start/finish
may not matter.

Not good. Start at the outside edge of each drywall sheet and work toward
the middle. 1 5/8" screws are overkill, but might be needed to grab the
rafter. Start along a wall parallel to a rafter and run the entire length
of a rafter. Move on to the next rafter and keep moving from one side of
the room to the other. If the screws pop through you may need to slowly
work each screw up a little at a time to keep them from popping through.
Go
slowly to keep from popping the screw heads.

The dimple bits work well in a drill for as much as you are doing. If you
know someone with a real screwgun that is better, but don't overdrive the
screws. They need to be just below the surface of the drywall.

!"1/4 screws are normal for 1/2 inch drywall and I was allowing a little
more for the old glue that might hold it away from the rafter a bit and to
give a little extra to draw the sheet up. The clutch in a real screwgun
makes it ALOT easier. Always could rent one or borrow one.

Jeff, if you start in the middle you are asking for trouble but it's your
baby....LOL...
