The Former and Method of Using It to Produce a Wrinkled Edge on the Tray
Place the sheet metal centrally over the hole in the board and set one end of the round stick in the center of the metal. Drive the stick with a hammer until a recess about 1 in. deep is made in the center. The edge of the metal will wrinkle up as shown in the sketch. It is scarcely possible to make two trays alike, as the edge almost invariably will buckle in a different manner.—Contributed by F. Van Eps, Plainfield, N. J.
A Homemade Exerciser
A weight machine for exercising the muscles of the arms is easily constructed by using two screw hooks, 5 in. long, and two small pulleys, 2-1/2 in. in diameter. An awning pulley can be used for this purpose. The hole at the top of the hanger will allow the pulley to freely turn at almost any angle. A paving brick or a piece of metal can be used as a weight for each rope.—Contributed by Sterling R. Speirs, St. Louis, Mo.
The Yoke of the Pulley is so Arranged as to Make It Move in All Positions on the Hook
A Book Covering
New books can be quickly and neatly covered to keep them clean by cutting a paper large enough to cover the back and sides when the book is closed, allowing 1 in. extra at each end to be turned over the front and back edges, then pasting on corners cut from used envelopes. The paper jacket can be slipped on or off easily when the book is opened, and it will keep a new cover clean while the book is being handled.—Contributed by Dr. John A. Cohalan, Philadelphia.
