An ordinary 1-lb. coffee can may be quickly fashioned into a most effective reflector for an electric bulb. The light is projected upon the target while the marksman's eyes are shielded. Of course, this device can be used for other purposes.
The can is shaped into a reflector by cutting it open along one side with a pair of snips, then following the circumference of the bottom halfway around on each side. Bend the flaps outward as far as desired and cut a hole in the bottom just large enough to insert the bulb, as shown.—Contributed by Burke Jenkins, Port Washington, L. I.

Making Small Taps
The owner of a private workshop has need for taps and occasionally wishes to make them, not because they are cheaper, but for the sake of experience or to get some special thread. In cutting the flutes, whether it be by hand or in a shaper, it is a good plan to give the flutes an angle, that is, to cut them, not parallel with the axis of the tap, but at an angle of 5 to 15 deg. with the center line. This makes the tap cut easier, giving it a wedge action instead of just simply pushing the metal off. The same method applies to counterbores and countersinks, which, when so made, take less power to drive.
