How to put two boards together for roof support.

Without bracing it is almost impossible to install trusses. Set thin evenly sized strips of wood under both ends of your boards to raise them off of your work surface. The longer the overlap distance the stronger the connection. When you glue and clamp your boards excess glue will seep out from the joints.

What you need to do to achieve this one is to butt the pieces and mark the dowel positions accordingly. Draw cutlines from the center of the top ridge board to its end and make these cuts with the sawblade set 1 8 in. Fasten the ledger board over the z flashing. Lay the boards across strips of scrap wood.

Install house wrap over the flashing. Raising the boards will keep your work surface clean. Use a bevel square to measure the cuts in the ridge board where the rafters will be placed. Line up the square with the plumb line then rotate it 180 degrees realigning the square on the other side of the board leaving at least 1 5 or 2 inches of bracing for the top edge above the seat cut and at least 4 inches of width for the support on the top cut.

Some bracing provides a way to put up the trusses evenly while holding them and other bracing supports them after they are put up. Trusses form the roof line on buildings and provide support for the lumber that holds shingles or other form of roof cover. An easy and invisible option of joining two boards together is by using a dowel joint. The side by side joists should be attached together by a nailing pattern similar to combining boards to form a beam.

You should overhang at least a couple of feet on each side of the beam. This will put saw tracks in the bottom piece showing you where to finish the cuts. Deeper than the cut. Position the doweling jig over the top of the mark and start drilling your holes.

It is important to make sure that the cuts are equal distances from one another and are all the same width and depth. Make gussets big enough to cover at least eight inches of each frame member at each joint. Install flashing approved for pressure treated lumber on top of the ledger. The holes should be around 1 16 inch deeper than the half the dowels length.
