Create a Temporary Beam
Start by fastening temporary wood blocks to the rafter tails (Image 1). This will protect the original porch wood and support the temporary beam. Join two sections of 2x6 for the temporary beam. With the sections joined, sister the two to create a 20 foot length (Image 2) which will span the porch. To get to the existing header, cut away the nails that attach the box beam (Image 3) and mark and remove some of the facing boards (Image 4).
