Drywall ceiling question

i'm not going to draw it for you because i don't understand the end vs field thing but basically if you imagine the joists run vertically on 2 ft centers this means center to center they are 2 feet apart, basically there is a joist every two feet. the point of nails is to hold the board to the joists so the nails have to go into the joists.

therefore the joists are in columns 2ft apart then the nails are in columns 2ft apart. the only variable left is the vertical (height) between each nail but like i said i don't get the end/filed/double nail bullshit.

here is a picture that shows the 2ft horizontal space vs the 7inch vertical spacing in fig. 5-21 and the double nail n the field at 12" centers vs single nail at the edges of the board in fig. 5-22

Thanks!

What he said, nails are nice if you fuck up and are off of the stud a bit. Hard to get a screw within 1/2" of the outside edge of the sheet. Otherwise, all screws, quicker and hold better too.

>X.Y

X = 2 feet / 24 inches, one every 2 feet left to right
Y = 7 inches, one nail every 7 inches forward/back

these guys have more rails than are required, for my description, imagine yourself as guy with drill.

if this isnt what you meant, i dont understand what you asked
