The main tower is supported on the roof by means of strong guy wires, set over four built-up guy towers of 1 by 1-in. wood, and 12 ft. long, as shown in detail L. The towers must be set so that the sail beam has proper play and be secured firmly to the roof. The top of the main tower is fixed to the guy wires by means of a guy plate shown in detail K. A plan of the arrangement of the sail beam, brace beam, and sail booms is shown at detail M. The sail beam is braced by No. 12 guy wires, O, attached at the top of the main tower, at the junction of the two sections of the beam, and similarly at the bottom of the main tower. The fastenings of the wires and braces should be made carefully, and they should be examined thoroughly both before and after the device is mounted in place. Grease the pivoted and other moving parts, and start the device slowly, bringing the sails into the wind as required for the desired speed.
Lawn Benches Made from Old Bedsteads
Painted Green, These Rebuilt Bedsteads Served as Lawn Benches
Old bedsteads were converted into serviceable lawn, or porch, benches, as shown in the photograph reproduced, by the addition of a suitable seat, properly supported. The transformation was a simple one. Only the foot and headpieces of the bedsteads were used. The front legs and other pieces were made from other wood. The front legs are of square stock, about 2¹⁄₂ by 2¹⁄₂ in. The crosspieces, supporting the wide board seats, are mortised into the legs and fastened with glue and screws. The seat is fastened from the under side by cleats. The lumber was carefully planed and sandpapered so that the benches presented a smooth finish when painted green, to match other outdoor furniture.—F. E. Tuck, Nevada City, Calif.
Repairing Wood-Wind Instruments
Wood-wind instruments sometimes “leak” at the joints or keys and make playing of the instrument difficult. Many such instruments are made in sections, with ends that telescope to form a tight fit. This fit is maintained by the use of a cork band cemented around the tenon end of the telescoping joint. The renewal of these cork joints, and the addition of new pads on the keys, will make an old instrument nearly as good as it was when new, so far as playing is concerned, provided the work is correctly done and the wood of the sections themselves has not cracked. Many musicians have spare time and can do this work themselves. The outlay for materials for the job is from 75 cents to $1.00. A small alcohol, or even a kerosene, lamp and an old knife, or old file, are required.
The Cork is Fitted Carefully into Place, and Glued
All traces of the old cork on the joint can be removed with sandpaper, leaving it as shown at the left. The cork comes in strips of about the proper thickness, and wide and long enough to allow for trimming. The ends of the strip should be beveled to make a ¹⁄₄-in. lap joint.
