��Handling Fine Screws

����IN repairing watches, clocks, spectacle s_ and other small articles, the difficulty of in- serting very fine screws into their respective holes may be easily over- come with the aid of a piece of paper. The screw is first pierced through a strip of stout paper, which is then held, with one hand, over the hole, while the screwdriver, held in the other hand, gently presses the screw into the required position.

When the screw is partly driven, the paper is torn away and the screw finally driven home. — George H. Holden. A Home-made Thumb- Screw

. WASHER '' I ^ HE materials

J- needed for mak-

^ing a thumb-screw, are a round- headed screw and a washer. Cut the washer as shown and sweat it into the slot of the screw. If the washer is a good fit, very little soldering will be necessary to insure a perfect union. — L. E. Fetter.

How to Make a Barometer

A SIMPLE but reliable bar- ometer may be made from an or- dinary tumbler and a test-tube or vial. Thevial, about two- thirds full of water, is inverted in the tumbler, which is nearly full of water. A tin cover A, provided with a hole in the center, will serve to sup- port the vial in an upright position. The greater the pres- sure of air, the higher the water will rise in the bottle, and vice versa. A little paper scale, ruled as shown, may be attached at B to indicate the degrees of fluctuation. — H. J. Gray.

���Making a Long Distance Shot with a Shotgun

IT is sometimes necessary to take a chance on making a long shot, in shooting into a large flock of ducks, especially in hunting on water. Cut a shell into two pieces, mak- ing the cut between the shots and powder as indicated in the illustration. If you have made the cut in the right place you will have a wad left at each end. Now put the portion of the shell containing the shots into the gun chamber and then put in the portion containing the powder. Of course your gun must be an open-bored gun. When you fire, the portion of the shell containing the shots will travel the same as a bullet, but upon striking the water it will burst and the shots will scatter in every direction, and you are sure to bag some game that would be otherwise impossible to reach.

Oiling Hammer Handle

A HAMMER handle which is well oiled will out- last two ordinary handles, as the oil penetrates the wood rendering it springy and also preventing dry rot. In the ac- companying illus- tration is shown the methods by which a hammer handle may be thoroughly oiled. A }4,-'mch hole is drilled in the end of the handle for a depth of about 2 ins. The harn- mer is then put in an upright posi- tion, and the hole filled with lubri- cating oil. When the oil has soaked into the wood, fill again, repeating the operation until the handle is well oiled. If desired, a small wooden plug can be driven into the hole to keep the oil from leaking out before it has completely soaked in. — O. B. Laurent.
