The material needed for making this porch swing chair are two pieces of round wood 2-1/2 in. in diameter and 20 in. long, and two pieces 1-1/4 in. in diameter and 40 in. long.
These longer pieces can be made square, but for appearance it is best to have them round or square with the corners rounded.
A piece of canvas, or other stout cloth, 16 in. wide and 50 in. long, is to be used for the seat.
The two short pieces of wood are used for the ends of the chair and two 1-in. holes are bored in each end of them 1-1/2 in. from the ends, and between the holes and the ends grooves are cut around them to make a place to fasten ropes, as shown at B, Fig. 1.
The two longer pieces are used for the sides and a tenon is cut on each end of them to fit in the 1-in. holes bored in the end pieces, as shown at A, Fig. 1.
The canvas is now tacked on the end pieces and the pieces given one turn before placing the mortising together.
The chair is now hung up to the porch ceiling with ropes attached to a large screw eye or hook.
The end of the chair to be used for the lower part is held about 16 in. from the floor with ropes direct from the grooves in the end pieces to the hook.
The upper end is supported by using a rope in the form of a loop or bail, as shown in Fig. 2.
The middle of the loop or bail should be about 15 in. from the end piece of the chair.
Another rope is attached to the loop and through the hook and to a slide as shown.
This will allow for adjustment to make the device into a chair or a hammock.
