How Do You Build A Barn Truss?
A barn truss is the support structure for the barn roof. These trusses are laid across the walls of the barn, and fastened together to form a skeleton structure on which roofing boards and shingles are laid. They can be built out of any type of material, and designed to accommodate a loft, or higher ceilings. Most often they are made of simple 2 x 6 boards. In some larger barns, 4 x 4 or 6 x 6 timber beams are fastened together to form the truss. Step 1 Measure the length and width of your barn to come up with your truss dimensions. Step 2 Cut your first two 2 x 6 boards at a 67.5 degree angle using a miter saw at both ends. Each angle should be facing in an opposite direction at both ends if you plan on installing eaves. Step 3 Lay the two ends together so the cut sides intersect and form the 22.5 degree angle of a typical barn roof. Step 4 Place a metal 22.5 degree angle brace across the intersection of the two boards and fasten with nails or bolts. Use bolts if you are using timber
