Nominal size vs. actual size of building materials:
The designated dimensions of lumber is not its' true size. Lumber is designated by its' nominal value, or the size of the lumber before it is planed down to its' finished size. be sure to use the actual size when you are planning your walls dimensions. For example, as you can see in the table below, a 2"x4" actually measures 1 1/2" by 3 1/2". For plywood, nominal size and actual size are the same.

• Two - 4'x8'x3/4" sheets of plywood
• Twenty - 96" (96 inches long) 2"x4"s
• +/- Two Hundred 3/8-16 T-nuts
• 5lb box of 2 1/2 inch black drywall screws (course thread)
• 2lb box of 3 1/2 inch black drywall screws (course thread)
• 5lb box of 2" black drywall screws (course thread)
  (Self drilling decking screws may be used instead of
  drywall screws. Self drilling decking screws are said
  to hold better and to be stronger, but in my experience
  drywall screws have performed quite well.)
• 12 Right angle metal brackets
• One sheet 80 grit sandpaper (optional)
• If you are using 4 prong t-nuts you'll need
  One tube Barges All Purpose Cement.
  You need this to glue the t-nuts to the back of the
  wall. Any glue that bonds to both metal and wood will do.
• Round Base t-nuts do not require glue.
