Step 1
Assemble Roof Trusses
1.
Screw 2x4 blocks to the 12' wide end of the floor, at the corner to trap the truss boards.
2.
Place (2) two 80-1/2" long 2x4 Truss Rafters and a 82" long Collar Tie together as shown
below. The Collar Tie has an angle cut on both ends. Affix 2x4 blocks around the 2x4s to hold
them in place and enable all trusses to be built the same.
3.
Secure the 2x4s at the top with a 8" x 20" wood gusset. Apply wood glue between the 2x4s
and the gusset. Nail the gusset to the 2x4s with 6d common nails, 14 nails per gusset.
4.
Install 12"x24" gussets to the ends of the collar tie. Glue and nail using 14 nails per gusset.
5.
Turn this truss over and apply wood gussets to the opposite side.
6.
Repeat to assemble (8) eight more trusses.
Do Not remove blocks from floor until Step 2 is completed.

Building Tip: To aid in the assembly of the trusses, temporarily screw 2x4 blocks to
the floor. This will insure that all the trusses are assembled the same. Use 2-1/2" screws.
There are short 2x4s, that may have an angle on one end, supplied in the kit.
