Cut the armrests and arm stumps to size (parts H and I). If done according to the plan, they will allow the back to tilt approximately 10 degrees from the perpendicular. These two pieces are butted together and held with wood screws covered with wood buttons. The end of the arm should extend 154" beyond the edge of the stump. The other end is screwed to the uprights. The arm stumps are held to the frame with % x 3" bolts.
Twenty feet of double-looped chain will suffice, with the shorter pieces that attach to the arm-stump/seat-frame bolts about three feet in length. S hooks will hold the two lengths together. To remove any stress on the roof of the porch, springs should be used there. Automobile hood springs are excellent for the purpose and can be obtained from an auto wrecking yard at a reasonable price.
The swing was finished with a mixture of a wood preservative such as McCloskey's Rot Fyter and a brown enamel. Mixing will take some experimentation, but if done properly, this treatment will seal the wood, stain it, and give it a gloss in one operation.
