A Garden Swing.

The length of a tread is 18 inches. In this ladder the sides are vertical. To mark out a side piece, draw on the floor a centre line and two parallel lines across and at right angles to it, 24 inches apart. Make a mark on one line inches from the centre line, and another on the other line 11 inches away. A piece is then laid up to these marks, on the centre-line side, and ruled far top, bottom, and vertical meeting-faoe. The other three pieces are marked from it. Construction then follows the course already described. The two halves of the ladder are united by a strap hinge inside the angle, as shown.

One leg of the hinge has to be secured with countersink-headed bolts, as getting screws into it would be a very tedious business. Or a pair of the special hinges sold for such a purpose may be used. These are screwed on to the outside faces of the sides.

Swing, A Garden. The framework for a swing is made out of two uprights A A of 7-inch by 3-inch wood, 11 feet 3 inches long, connected at the top by a crossbar of 7-inch by 3-inch wood, and below ground level by two 8-inch by l.V-inch boards, BB, 6 feet long, nailed on to both sides.

The uprights are tenoned through c and firmly wedged, the joints being first woll smeared with white lead paint to prevent water entering. Two short boards, D D, are nailed to the bottom ends of the uprights to prevent any settlement after the swing has been erected.

All underground parts should be well creosoted before being buried. In selecting the timber make sure that it is sound and free from large knots. A weak place in an upright near ground level, where the strain is greatest, might cause the wood to break.

The uprights are 4 feet apart, and c is long enough to overhang them 4h inches at each end. On the top, o is bevelled from the centre line towards each edge, to throw off the rain.

Two large eyebolts are fixed through the crossbar, 18 inches apart, for hooks at the end of the swing ropes, which will then be easily removable. The ends of the bolts should be burred over the nuts to prevent these loosening.

The framework is buried 3 feet deep in the ground, and packed with stones, brick bats and earth, wetted and rammed hard.

The packing should be given a week or two to settle before the swing is used.

For the seat use a board 0 inches wide, 2 feet long, and IA inches thick. All edges should be well rounded off.

Timber, Sizes and Selection. Deals, battens and boards ate sawn to certain standard dimensions with which the amateur should be familiar, so that in planning out work he shall not include parts of unusual thickness or width, which will have to be worked down from larger stuff.

Deals, 4-inches thick are sold in widths of 11, 9, 8, 7, and 6 inches. Deals 3-inches thick have widths of 11, 9, 8, 7, 6,5, 5, 4, and 4 inches. Deals 2i-inches thick run 9, 8, 7, 6£, and 6 inches and 2-inch deals 11, 9, 8, 7, 6, 5 and 4A- inches wide.

Boards have widths of 11, 9, 8, 7 and 6 inches, and thicknesses of 1$, 1 ½, 1, J, and inch.

These measurements all apply to timber in the rough. If machine planed or finished, they are of course smaller by the amount removed by the plane. Thus, a 9 by l½ inch board will measure say about 8f by 1 ½ inches when planed.

Quartering?, so useful for framing out-houses, and for a great deal of indoor and outdoor work, are sold at any timber yard with sections (in the rough) of 4 by 3 inches, 3 by 3 inches, 3 by 2 inches and 2 by 2 inches.

Matchboard is sold in 6, 5, 4 , 4, 3 I and 3-inch widths. The effective width is about I-inch less than the nominal, as the tongue takes J-inch and the edge-planing an equal amount.
