Step 3A Assemble Back Wall
1.
Position (2) two 68-1/2" and (2) two 48" long 2x4s together and indicate with 'X' marks, where
the wall studs will be located. Mark plates with the letters 'A', 'B' and 'C' so frames are correctly
orented.
2.
Install 72" wall studs between the top and bottom plates. Assemble wall frames with 10d sinkers.
Nail both wall frames together.
3.
Square wall frame. The measurement should be 138-1/2". Install (2) two full width siding
panels. Install the first siding panel with the 'LAP' edge extending 3-1/2" past the end of the
wall frame. Install a full width panel next. The siding should extend 3/4" below the bottom plate
and flush with the top plate. The last siding panel will be installed in a later step.
