The framework of the swing is largely of two-by-four pine. Smooth up the two long runners and round the ends slightly. Prepare the two crossbars, making the ends perfectly flat and square. Towards the lower end of each of the four corner posts a section is cut out so that the long runners will set in half an inch, as shown in the end view drawing. Mortises, three-fourths of an inch wide and one and one-quarter inches deep, should then be cut for the back rail.

The pieces may now be put together. At each corner a pair of lag-screws are inserted through the corner post and runner into the cross-bar. Three-eighths-inch screws, with a washer under the head, are used. Grooves can now be cut for the five back and four end boards. After the back rail is prepared and similarly grooved, tenon to fit the mortises in the rear corner posts. The arm-rests should now be grooved to receive the end boards. After preparing the nine small boards, and fitting them to the grooves made to hold them, the back rail and armrests may be put in place. Use glue at all these joints, and also wire nails driven in from below or behind as required. The connection of the runners and cross-bars should be reenforced by a block in each of the four corners secured with nails and glue. These blocks will not be seen when the bottom is in position. Strips nailed on the inside of the framework set so that the seat-line will fall about half an inch below the top of the runners, support the bottom.
