Step 2—Rectangular spacers are cut from 3/4" plywood scraps.
Step 3—Treat all pieces with CedarShield per product instructions.
Step 4—Using polyurethene glue, spacers are glued and stapled every 4-6 inches along length of studs with ends left open for later addition of a longer spacer for connection to perpendicular studs (see photo at bottom).
For studs that will be directly bolted to the 3" high tabs along the chassis:
Step 5A—Score a line one-ply deep 3.25" from end of strip and chisel out the one-ply deep end piece.
Step 5B—Glue and staple a spacer flush with the end of the second (top) strip.
Step 5C—Align the top strip flush with the edges of the bottom strip and so that the end with the flush spacer from Step 4B is 3/4" above the chiseled-out end (this is the difference in height between the top of the metal chassis and the top of the rough floor—see photo below).
For standard studs:
Step 5—Lay another strip on top, edges and ends are squared, then glued and stapled.
The stud is now ready for immediate installation to the chassis tab.
The photo below shows how a 3/4" strip is inserted into the end of two studs and then glued and stapled from each side to join them together:
