Making a Lawn Chair

��THE accompanying drawing sliows a chair for use on the lawn. The materials required are hardwood strips J^ in. by lyi ins.; one ^^^ in. round iron or steel-rod threaded on each end with two nuts; two ^-^-in. bolts, 2}^ ins. long under the head; two ^-in. bolts 2I4 ins. long with two nuts each; two ■■2-in. pipe, some ^-in. washers, and from twelve to sixteen ounces of upholsterer's tacks.

To make the chair shown cut two strips 4 1/6 ins. long, and two strips say forty to forty-si.\ inches long. Mortise near top of the two long strips for the crossbar. Cut the mortise >-§ in. by 2 ins. in size. The crossbar is i ft. i/io ins. long with a )4-\n. shoulder on each side at each end 14, in. long.

At the other end bore a ^-in. hole in each strip and fit a Js-'f- dowel into it. This dowel is also i ft. i/io ins. long. All these joints should be carefully squared, fitted tight, glued and wedged. Glue the wedges before you drive them, and make chisel-splits for starting the wedges. Do the same thing to the shorter pieces. Bore a %-in. hole in both short pieces at the upper end. This is for the bolt holding the arm-rest. Cut out the arm-rests, as shown in the illustra- tion, for the adjustable hooks. These hooks are made by boring ^2 -in. holes in the exact center of the strip and making saw-cuts to remove the wedge of

��wood. Round both ends and also round the top ends of the shorter frame.

Lay off fifteen inches from the bottom of the long frame, and twenty-five inches from the bottom of the short frame. Bore 3^^-in. holes in both, at the points marked. The steel pivot rod, /"s-in. diameter, is twent\-five inches long. It is threaded on each end for a hexagon nut. Six ^-in. common washers, and a piece of ^-in. wrought- iron pipe i ft. 8 ins. long are required.

Put the rod through the hole in the short frame. Put on a washer; then through the hole in the long frame, another washer; slip on the piece of pipe; a washer; hole in the long frame; a washer; hole in short frame; another washer. Put a washer on the outside of the short frame, and put on both nuts; screw up fairly tight, and burr the end of the rod, riveting it down on the nuts, so they cannot back off.

Pivot the arm-rest in the hole at the top of the short frame, with a ^-g-in. bolt 2% ins. long under the head, but make it a loose fit, and burr down the threads to keep the nut in place. Bore a hole through the side-bars of the long frame, 2 ft 3 ins. from the top. Put into each hole a ^-^-in. bolt, 2^,4 ins. long under the head, with a thread 2 ins. long. Screw up a nut on this thread until it joins. Push the thread through the bored hole from the outside, screw up the other nut tight, and burr the threads. The notches in the arm-bar hook on this bolt and make the chair adjustable.

Fasten the crash or canvas to the crossbars with tacks, tacking on top, and taking a full wrap of the canvas around the crossbar so that the tacks are covered. This prevents strain on the tacks when the chair is in use. Allow slack as shown, so that the boily of the sitter cannot touch the crossrod. The canvas will con- form to the body like a hanmiock. The chair should be painted or varnished for protection against the elements.

This practical lawn ciiair can be subjected to nnich wear and tear without suffering any dam- age. — H. S. RlNKER.
