IN ANSWER to B.R.L., there are two uses I can suggest for burned-out fluorescent lighting tubes—one for recreation and the other for utility. Throw a tube into a swiftly flowing stream, and with a .22 caliber rifle shoot off the end. As the tube bobs up higher, keep on shooting until it sinks.

RADAR... Magic Eye That Sees the Invisible
VEIL OF CENSORSHIP LIFTS TO REVEAL NEW SECRETS OF THE VERSATILE WEAPON IN WHICH WE LEAD THE WORLD
[no value]
[no value]
JAMES L. H. PECK
RADAR sees all, hears all, and tells all," an AAF pilot once remarked. "It has penetrated everything but the thick veil of secrecy behind which it has been screened." Now that the boys in the Pacific are even using radar to fish with in their spare time, its story has come crackling through censorship, too.

LIKE every other revolutionary new weapon, radar has been met with defensive measures. The most common of these are artificial reflecting agencies and "jamming" with other kinds of radio sets. "Window"—strips of paper-backed tin foil — has been used effectively by both Allied and Axis planes.

A CUBIC INCH of a star known to astronomers as the White Dwarf weighs about a ton, almost 6,000 times as much as a cubic inch of lead. This star may have pointed the way to atomic power—a discovery so momentous that the noted French physicist, the Duc de Broglie, calls it comparable only to primitive man’s discovery of fire.

BENT to shape from a single length of wire, this lens holder has a viewing angle of about 60 deg. from the vertical, a position often more convenient than the usual 90-deg. angle of table magnifiers. However, the lens can be placed in a horizontal position simply by changing the angle of bend between the uprights and the lens.

CAN you find six sanding errors in the drawings—two in No. 4? The correct answers are given below. 1. Pieced disks applied directly with stick adhesive will be thrown off. Back the joints with pasted cloth or strong paper, and then apply the assembled sheet in the usual way. 2. Do most sanding at the side where the disk travels downward and keeps the work from rising.

WALTER E. BURTON
ONE of the most plentiful metals in the postwar period is likely to be aluminum. It is bound to find its way into the home workshop where the craftsman will, in many cases, prefer it to steel and other metals because of its cheapness, strength, and lightness, and because of the ease with which it can be worked.

ALUMINUM may be machined at about the same rate as brass and much faster than steel. Comparatively low speeds are useful in roughing cuts where there is a hard abrasive outer surface, but often the only limit to cutting speed for aluminum is the top speed of the machine itself.

JOHN KRILL
IT IS often difficult to file a surface with an area wider than the length of the file. Fingers bump the edge of the work when the handle is left off, and uneven pressure causes poor finish. A slight alteration will remedy this. Slip the handle off and heat the tang red hot; then make an L-shaped bend as indicated in the drawing. Be careful not to heat the cutting teeth. The bend should offset the handle just enough to give finger clearance.

MOLTEN solders have been found to reduce the diameter of copper wire and cause some embrittlement of the parts subjected to high temperatures. In tests conducted by engineers of the Fairchild Camera & Instrument Corp., of New York, it was shown that destructiveness was greatest in fine wires and increased with the tin content of the solder. For delicate work, therefore, solders of low melting point should be used.

E. M. L.
ONE great fault with reconditioned paintbrushes is the bushiness of the bristles caused by dried paint at the roots. No matter how hard you work, some dried paint stays. This can be corrected with a ⅜" wrapping of heavy twine starting at the ferrule. Wrap the twine tightly, tie it firmly, and then squeeze the base of the bristles in a clamp. Let the brush dry thoroughly and shape it carefully. Pressure flattens the bristles to almost normal thickness, and the twine prevents bulging edges.
