Full Answer

  1. Design the wood truss

    Ensure that the measurements for the truss are proportionate to the measurements for the rest of the building. Make sure that the plans for the truss include the measurements for the raft members, the top chords, the bottom chords, the overlaps, the joist member and the diagonal braces.

  2. Cut the wood

    Start by measuring the width of the building. Cut a 2-by-4 board according to this measurement. Cut the wood with a power saw.

  3. Build the peak

    Place the 2-by-4 board on the ground. Arrange two more boards of the same size to form the peak of the truss. Ensure that the cut pieces of wood are at the correct angle and are of identical size.

  4. Fix the boards

    Attach the boards at the edges. Place mending plates on the boards. Fix the plates to the boards with a sledge hammer. Secure the plates with screws.

  5. Add the finishing touches

    Cut 2 angle braces according to the measurements. Then cut a vertical brace to fit between the horizontal and angled beams. Attach the angle braces to the truss with screws and mending plates. Use the same process to construct the remaining trusses.
