Position the doweling jig over the top of the mark and start drilling your holes.

How to put two boards together for roof support.

The side by side joists should be attached together by a nailing pattern similar to combining boards to form a beam. Cover the top of the flashing with window door flashing tape. Deeper than the cut. Fasten the ledger board over the z flashing.

Now you can put the pieces together with a couple of 8d nails near the end of the splice. An easy and invisible option of joining two boards together is by using a dowel joint. Raising the boards will keep your work surface clean. Draw cutlines from the center of the top ridge board to its end and make these cuts with the sawblade set 1 8 in.

Glue them in place with liquid nails or some other construction adhesive and fasten in place with 3d or 4d box nails two inches apart in wiggly lines down both edges of each truss member. The longer the overlap distance the stronger the connection. Install flashing approved for pressure treated lumber on top of the ledger. You should overhang at least a couple of feet on each side of the beam.

The holes should be around 1 16 inch deeper than the half the dowels length. Use a bevel square to measure the cuts in the ridge board where the rafters will be placed. Trusses form the roof line on buildings and provide support for the lumber that holds shingles or other form of roof cover. Set thin evenly sized strips of wood under both ends of your boards to raise them off of your work surface.

What you need to do to achieve this one is to butt the pieces and mark the dowel positions accordingly. It is important to make sure that the cuts are equal distances from one another and are all the same width and depth. Some bracing provides a way to put up the trusses evenly while holding them and other bracing supports them after they are put up. Without bracing it is almost impossible to install trusses.

Lay the boards across strips of scrap wood. Install house wrap over the flashing. This will put saw tracks in the bottom piece showing you where to finish the cuts. Fasten the house wrap to the wall with house wrap tape.
