WELDING IS A WAR BABY that came along just in time to carry a big share of the arms-production load. Maybe you know all about welding already. If not, you’ll be interested in an article that explains how the man (or woman) in the mask is putting new strength into our sinews of war.
A Beef That We Haven't Got Enough Meat in Our Problems
This Puzzler Will Have You Going 'Round in Circles
We're Happy To Give Credit Where Credit is Due
Dad Gets His Orders on Holding the Home Front
Credit the Italians. They Always Come to a Fast Stop
But What if a Dog Just Doesn't Like to Keep House?
HAVE just finished reading in your January issue the idea that A. H. W. of Phoenix, Ariz., dreamed up for using light Pikes Peak air to fill balloons and dirigibles. It reminds me of a fellow up here who, in order to spare himself the expense of the antifreeze he needed for the cooling system of his car, rowed several miles out into Lake Michigan to get some of “that blue water that never freezes.
EVERY MILITARY COMMANDER should have a psychiatrist on his staff, according to Dr. Emilio Mira, of the University of Buenos Aires. Under the terrific strain of seemingly unending battles that seldom gives them a chance to rest, Dr. Mira says, military leaders are very apt to push themselves far past the limits of their nervous endurance.
THE letter above is a composite of several I have received, and of many conversations. Perhaps this is a good time to give a comprehensive answer. I began my explorations in tropical jungles about 35 years ago, the wilds of Venezuela. This experience has left me with an undying affection for these mighty trees and the wild creatures which live in their shadow, but this emotion is combined with a thorough respect which ever increases.
Pup Tents for Army Flyers Designed for Modern Comfort
SLEEPING in jungle, desert, or arctic waste—or wherever their tasks may take them— still means a good rest for Army flyers equipped with the Air Corps A-2 shelter, this war’s modern descendant of the pup tent. It is a highly portable, waterproof covering that can be put up in a few minutes with four light aluminum tent poles and is easily camouflaged.
AIRPLANES leave trails in the atmosphere that can be picked up, if a spotter is quick enough, like those of game sought by a hunter. Some of them, especially trails left by a plane’s exhaust at high, cold altitudes, endure for some time, while those made by wing tips creating vortices are audible as well as visible.
RED, green, purple, and yellow fields of snow and ice—rare curiosities of nature—owe their hues to myriads of microscopic, cold-enduring plants. Some of the world’s most striking displays recently have been discovered and studied in Alaska by E. Kol, Hungarian woman scientist.
NEW AERIAL PICTURES SHOW ENEMY TERRITORY IN THREE DIMENSIONS
ALDEN P. ARMAGNAC
ENROLLED in classes at a Cambridge, Mass., laboratory, picked men of the Army, Navy, and Marine Corps are learning a new way to make aerial photographs possessing depth, or a third dimension. The pictures clearly reveal bomb damage to industrial plants.
TRUCK TRAILERS with telescoping axles are being used for hauling airplanes from factories to seaports and other shipping points. Axles can be extended to a width of 12 feet, and planes’ landing wheels are run up bridgelike ramps to rest in special troughs.
A JIGSAW PUZZLE OF STEEL, WITH A QUARTER OF A MILLION PIECES AND 97 PREFABRICATED SECTIONS, FORMS A NEW VESSEL FOR VICTORY
WHEN the 10,500-ton Robert E. Peary,, on November 12, 1942, slid down way No. 1 of Henry J. Kaiser’s Richmond shipyard after being on the ways only four days, 15 hours, and 26 minutes, it did more than set a world’s record in speedy shipbuilding.
DOWN the Valley of the Jordan, after the war, there may flow water from the Mediterranean to supply electric power for life and industry in the resettled land of the Bible. That is the plan of Pierre Gandrillon, a French scientist and engineer, who had completed his work to the point of actual survey when the war intervened.
Muscles as Well as Minds Are Being Put to the Test in U. S. Plants. Here Are a Few Tips to Help Banish That War-Worker Weariness
OF THE millions of men and women in U. S. war plants, many are "green" to hard physical labor, and most are learning for the first time the agony of muscle strain. As critical as the materials they are making, however, is the ability of these operatives to keep working long hours, day after day, without loss of efficiency.
THE ARMY ASKED FOR A MIRACLE... THE ANSWER WAS The B-26
HOW GLENN L. MARTIN BUILT A MEDIUM BOMBER THAT FLIES LIKE A CLOSED-COURSE RACER
William S. Friedman
IF THE Japanese have not developed any profanity in their language in 2,000 years, they must be thinking up some at this late date to describe the U. S. Army’s B-26 medium bomber. On this side of the Pacific, no well-informed observer has offered a temperate opinion of this airplane.
RIDING at anchor in the Capitol Yacht Basin at Washington is one of the strangest ships afloat. Appropriately named the Phantom, she resembles anything but a sea-going craft. Her deck is almost flush with the water line. Missing are smokestacks, superstructure, and cabins.
ROWING a boat while facing forward is said to be made practical for the first time by an invention of Percy M. Griffin, of Albany, N. Y. The device consists of an oarlock in which the forward-and-backward motion of the oar handle is reversed in the oar by means of segment gears as shown in the drawing above.
YOUR clothes are due for a lot of changes, and you will like them all. You'll soon be wearing suits made partly out of skim milk, soybeans, peanuts, seaweed, bark, cellulose, plastics, and possibly even glass, and you won’t even have to get used to it.
SOUND TRAINING AND GOOD EQUIPMENT NOW BRING SHIPWRECKED SEAMEN BACK TO PORT
MERCHANT MARINE SCHOOLS TEACH MEN TO PLAY SAFE
IT WAS all over before you could say "All hands on deck—man the lifeboats!" One minute Marty was standing watch on the graveyard shift, wondering if he really saw a streak of foam creasing the inky waters— the next, the whole ship heaved and shuddered and, with a terrible splintering crash, split in two.
SCIENCE HAS DISCOVERED UNDREAMED-OF WAYS TO USE GLASS—BUT STILL HASN'T FOUND OUT JUST WHAT IT IS
GLASS NOW DOES THE "IMPOSSIBLE"—AND PROMISES TO DO A LOT MORE
ALTHOUGH man has manufactured glass for some 10,000 years, he still doesn't know precisely what it is or how to describe it accurately. The scientist may call it "a super-cooled liquid,” or "an amorphous solid,” but these and other definitions don’t describe glass in the sense that H2O, for example, describes water.
SHORTLY after America entered the war it was discovered, in the testing of an experimental bombing plane, that while a flyer of average size could easily squeeze through the escape hatch to bail out of the ship, a big flyer could not possibly make a jump without first taking off his parachute.
AIRPLANE CONTROLS can now be studied, and their operation quickly learned, with the scale model shown at the right. Here an aviation student at Franklin and Marshall College, with his hand on the “stick” and his feet on the “pedals,” puts the model through precisely the same maneuvers that he will have to perform in an actual plane.
PLASTIC SCABBARDS for bayonets, which will help to lighten a soldier’s equipment, are now being issued to U. S. troops in all parts of the world. Made of Tenite, a plastic material made from cellulose acetate butyrate, the new scabbard, besides being light, is tough and durable, and comes as a welcome replacement to the old scabbard which was made of leather and wood.
TEST RUNS on new Pratt & Whitney airplane engines are now being utilized to generate electricity in one of the company’s New England plants. By means of equipment developed by engineers of the company and General Electric, the engines, instead of turning propellers during their testing, now turn generators and pump electricity into the plant’s power system.
HANDLEBARS attached to a .50 caliber antiaircraft machine gun make firing the weapon seem much like riding a bucking motorcycle at high speed over a bumpy road. The photograph at the right, taken on a patrol vessel somewhere on the Pacific, shows a steel-helmeted Coast Guardsman in action.
RUBBER FROM THE FARM has become a reality with commercial production of Agripol by Reichhold Chemicals, Inc., Detroit, Mich. Made from soybean oil and ethyl alcohol, the chemurgic rubber is not now offered as a substitute for natural rubber in automobile tires but will be used for many industrial and domestic purposes.
AIR-RAID WARDENS and other civilian-defense workers have enlisted an “electric sentry” manufactured by the Zenith Radio Corporation to listen for urgent telephone calls. A transmitter unit plugged into an outlet near the phone, as below, relays the ringing of the bell to a receiver unit plugged in anywhere about the house.
THE "SENTINEL" is the Army’s latest fast-climbing, highly maneuverable liaison plane. Capable of landing in or taking off from a cow pasture, it has been designed to hover at low speeds so that its observer can “hang” in the air to direct artillery fire and troop movements by radio.
UNDERGROUND production of aircraft is speeded up in this British plant by means of a tiny railroad which carries parts from one shop to another. Visiting American plane builders are shown getting a ride.
COMMAND BOATS for use by the Army in the landing of invasion forces are one of the many types now being turned out by Chris-Craft. 42 feet long, and particularly seaworthy, the boat carries guns fore and aft, and has been especially designed to meet all requirements of transporting officer personnel.
MOTHER NATURE was the first war inventor. To protect her creatures against their enemies, or to help them hunt their prey, she has provided them with weapons and tactics that in many cases anticipated the vaunted “new weapons” of modern human warfare.
AN ADAPTATION of the sewing machine's "uninterrupted thread supply" to surgical suturing has resulted in a new stitcher that cuts precious minutes from operating time and eliminates the danger of spreading infection. The secret of the instrument’s speed is that the needle can shuttle back and forth without stopping for fresh thread with every stitch.
YOUTHFUL student scientists are now getting a real break at the Alexander Smith & Sons Carpet Company in Yonkers, N. Y., largest carpet manufacturers in the world. Looking ahead to the time when their technical personnel would be reduced by war demands, the Smith company last summer began employing, as “junior specialists,” Yonkers High School seniors who had shown a marked proficiency in science courses.
DAREDEVIL CAMERAMEN SHOOT HISTORY'S MOST PHOTOGRAPHED WAR
This Is the Army’s Mobile Photo Unit
CAMOUFLAGED machine-gunners wriggle to the edge of a thicket and peer into a clearing below. We see their faces at close range—strong, alert faces with the same purposeful glint as their guns. Then we get a view of the other side of the small valley where a second machine-gun detachment is crouching among the trees.
DIRECT READINGS are possible with a new caliper for machinists, which measures down to 1/32 of an inch and has a maximum capacity of four inches. Its white scale markings on a black background are easily read even in a poor light, and the simplicity of its operation makes it an accurate and speedy tool to use.
A NEW type of incendiary bomb carrying a delayed-action explosive charge, now being used extensively by both Germany and Japan, has made it necessary for the Office of Civilian Defense to revise its instructions on fire fighting. Because it is impossible to tell when the bomb will explode—the time fuse can be set to ignite anywhere up to seven minutes after the bomb has struck—it is necessary to use the greatest caution in fighting the blaze which is set immediately on impact.
YOUR CLOTHES HAVE TO LAST LONGER NOW—AND IT WILL HELP IF YOU KEEP THEM SPOTLESS. HERE’S HOW TO DO IT:
THESE MATERIALS WILL MAKE YOUR CLEANING EASY AND THOROUGH
ANDREW R. BOONE
ABOUT your clothing and other textiles around the house: better keep 'em clean. Most of them must survive the war, because goods of that sort are disappearing from the market. So be prompt in cleaning them, for all stains, from blood to ink and perspiration, get tougher with age.
Guns, Speed, Armor, Durability —These Have Given Us the Lead on the Proving Grounds of War
HERE ARE SOME OF THE POINTS IN WHICH OUR TANKS EXCEL
WHAT TANKS SHOULD NOT DO
WHAT TANKS SHOULD DO
VOLUTION OF AMERICA’S MECHANIZED MIGHT. OUR TANKS FROM 1917 TO TODAY-AND TOMORROW
THE battlefield value of a tank depends on three qualities: the power of its guns, its ability to take those guns where they can do the greatest possible damage to the enemy, and its mechanical durability. In the fighting on the African desert which was climaxed by Rommel’s rout, American light and medium tanks lend-leased to the British—a few of them handled by American crews—consistently outmatched German tanks of their classes in all of these qualities.
HOW TO DIAGNOSE THE CAUSE OF TEN COMMON BRAKE FAILURES
CHECKING and servicing your own automobile regularly becomes of primary importance now that more and more mechanics are being called into war work and parts are becoming harder to replace. And in your periodical check-up, do not fail to test your brakes and readjust them when necessary—their efficient operation, aside from the safety factor, will save wear on many other parts.
GIANT TRAILER TRUCKS 73 feet long, like the one shown below, are to haul bomber parts from factories to assembly plants 1,300 miles away. Two of these units, which were designed to relieve rail congestion, are equivalent to seven freight cars and can be loaded in less time.
How Neglected Puncture Holes Can Destroy Your Tires
TIRES may be sabotaged from within, points out A. L. Murray, president of the Auburn Rubber Corporation. If tiny holes in the casing due to punctures are neglected, the destruction of the tire is only a matter of time. The average car owner, Mr. Murray says, looks only at the outside of his tire and doesn’t realize that while the tread is its wearing surface, its true strength really lies in the inside structure.
CARBONIZED VALUE GUIDES are quickly cleaned with a set of five interchangeable brushes, which remove hard or soft carbon without scratching the side walls. One handle takes all brush sizes, and the metal shank is sufficiently long to protect the hands from projecting studs.
New Headlight Hoods Solve Problems of Dim-Out Driving
A SALESMAN motoring to New England a short time ago was stopped seventeen times by the local police between New York and Boston because his lights did not comply with various local wartime regulations. There were, he found, different rules in different areas, and while some enforced dim lights or none at all, others required that head lamps be as bright as usual.
1 OLD-STYLE TIRES of large rim diameter can be made to serve on small wheels by the use of the adapter shown in the drawing. Here a 5.00-by-19 tire and rim are mounted on the rim of a 6.00-by-16 wheel, but with slight changes the method can be applied to other sizes.
Gus Foots the Bill as a New Mechanic Bungles a Job
IT WAS a fine sunny morning, and Gus Wilson should have been whistling as he went about his work in the Model Garage shop. But he wasn’t. George Knowles noticed this the moment he came in. "What’s biting you this grand and glorious morning ? ” he wanted to know.
SLIDES MADE FROM ORDINARY NEGATIVES PRODUCE BRILLIANT IMAGES ON THE SCREEN
WALTER E. BURTON
FOR a new thrill in photography, try making black-and-white slides for projection, instead of prints on paper. An ordinary print is seen by reflected light, but the maximum beauty of a photograph is best brought out by transmitted light. Transmitted light pictures, or transparencies, are capable of showing a fuller range of tones, and possess greater brilliancy.
EXPOSURE METER MANUAL Issued by a manufacturer of exposure meters, this handy 97page manual deals with the more scientific aspects of photography, particularly those relating to exposures. The technique of using an exposure meter is explained in considerable detail, and the text is illustrated with striking pictures by well-known photographers, and with diagrams and charts.
A PLASTIC PROJECTION REEL with a patented threading feature and a self-locking film catch is now available to home-movie fans. It has a convenient slot in one of the reel arms for the film to slip through, enabling one to thread it quickly and easily even in darkness.
TRIPLE-PURPOSE PROJECTOR Color slides, black-and-white slides, single-or double-frame film can all be shown with the portable projector pictured above. Film is held flat in the optical plane by glass pressure plates and is ready for showing again immediately after use without rewinding.
FOR WEIGHING or otherwise handling small amounts of chemicals, a novel scoop can be made from an ordinary pen nib and holder. The pen nib is placed point first into the holder, which forms a convenient handle for manipulating the scoop. With this you can place as small an amount as a crystal or a grain of chemical on the scales.
READER W. S. is making a good choice. The fluorescent tube comes so close to being the ideal light source for enlargers that it seems a poor compromise to use anything else in homemade ones. Fluorescent tubes give a brilliant bluewhite light of very high photographic value, and are so nearly heatless that negatives can be left in the carrier of the light box illustrated for several hours and still come out cool to the touch.
OWNERS of flash guns that take special plugs for their miniature outlets are finding it difficult to get plugs. Such an outfit can be adapted simply to standard 110-volt plugs by slipping a so-called 110-volt “three-way socket” into the gun, as shown.
Glass Palette Fitted in Flat Box Is Aid in Spotting Prints
C. H. COLES
HERE'S an easy way to do your print spotting without staining the family china. Take a shallow box like the ones in which cut films come, and fit pieces of blotting paper to both halves, inserting them snugly so they won’t slip out. Then cut a piece of clear glass the right size to go into the bottom half of the box, and you have a palette on which to smear water colors for matching print tones.
DOMESTIC SUBSTITUTES SERVE CRAFTSMEN AS MODEL MATERIALS MARCH OFF TO WAR
WHEN war was thrust upon us, it became evident that model builders would have to do without many of the materials they normally took for granted. Rubber became very precious, and in January, 1942, the manufacture of rubber thread for model use was suspended.
MANY occasions arise in the shop when decimal dimensions must be measured with an ordinary rule graduated in fractions of an inch. To determine the fractional equivalent of a given decimal, multiply the decimal by the denominator of the fraction most convenient for your use.
THIS attractive folding clothes hamper is easily carried to the laundry for sorting clothes before they are washed. The simple frame is made of dowels, while the cloth bag is so designed that the framework holds it open rigidly and, at the same time, allows it to be folded easily.
BLACKOUTS ARE CAMOUFLAGED from the inside through the use of the decorative shade above. Made of heavy black paper and absolutely opaque, it looks like a Venetian blind by reason of a design applied to its interior surface. It may be hung in place or rolled up for storage in few seconds, and is available in four convenient sizes designed to fit almost any window in the home.
FOR complete modernization of a kitchen, a systematic method of storing equipment in use every day must be provided. Whether you are making a fresh start by remodeling, or already have some up-to-date units installed, it will pay to give additional thought to timesavers of this nature.
A PAIR of attractive wall holders for ivy or other potted plants can be made from one wooden chopping bowl and a little ½" lumber. For the two designs shown, a bowl 11" in diameter and 2¾" deep was sawed in half with the grain, and each half was fastened to a wooden back-board with wood screws.
DESIGNED on simple, sweeping lines, this decorative mirror harmonizes well with modern furnishings. Making it is a comparatively simple job, although the work must be carefully laid out. The dimensions given are for an 11¾" mirror. It is simplest to use a paper pattern, which will serve for both the main parts.
FROM thousands of American homes, offices, shops, and factories, men have gone forth to join the armed services of the United States. “Let’s not forget them" is the slogan of those who stay behind, and to this end service flags and plaques of various kinds are displayed.
Holds a Guest's Suitcase for Easy Packing and Unpacking
SOLVING the problem of where to put suitcases for packing and unpacking, this sturdy luggage stand saves wear and tear on bedspreads and furniture, and folds so compactly it takes up little room in a closet when not needed. Although the one shown was made from walnut, any strong, durable wood can be used.
IF A SOCIETY for the prevention of cruelty to leather were formed, there is no doubt that many of us would be found guilty of abuse and neglect. These days, however, careful maintenance is the watchword for all goods that cannot be conveniently replaced, and leather—one of the oldest and most useful materials known to man—may have its life multiplied many times over with proper treatment.
WHEN the threads of a bicycle pedal are stripped at the end, the pedal can still be made to serve by countersinking the crank on both sides, and beveling the pedal spindle on the grinding wheel, as shown in the drawing, so that good threads will project far enough through the crank for the nut to get a firm grip.
THE method of drawing a perfect ellipse with a pencil and a loop of string placed around two brads or thumbtacks, as shown in the diagram at the left, is frequently used in laying out work. An easy way to find the proper spacing between the brads and the correct length of string to be used is as follows:
HOT buttered popcorn, that perfect snack for frosty evenings, will be welcomed even more enthusiastically, by children and grownups alike, if served in this attractive cart. The four scoops, which are lifted out by handy finger holes, make convenient individual servers for guests.
QUICK-GLANCE SPEED CHARTS mounted on machine tools having step pulleys tell instantly how to obtain the nearest correct speed for working various materials, and do away with constant thumbing of the instruction book. The speeds obtainable on a drill press, for example, may be typed or lettered on paper and glued to the belt-guard, as in the photograph at left.
ALL the power that drives America's mighty war machines is transmitted through wheels of steel. These must be carefully designed and skillfully machined. In making the spur gear and shaft of a U. S. Army “blitz buggy,” for example, time is saved and strength and precision are gained when both the shaft and gear are turned from a single piece of steel, eliminating the use of fragile pins, keys, or splines, such as would be required to lock the gear on the shaft if the two parts were produced separately.
Many craftsmen have scraps of plastic left over from completed work. Here are three projects that can be made from such odds and ends. None calls for a piece longer than 4", yet all show off the beauty of this material to the full.
ERNEST R. DEWALT
CIGARETTE BOX. Clear plastic, maple, and walnut are combined in this unique occasional piece, displaying both the plastic and the woods to good advantage. A clear-plastic tube 2⅛" in diameter and 3½" long is sawed apart as shown in the drawings at the left to form both the body and the lid.
THE plating of nonmetallic articles is generally thought of in connection with baby shoes, but other objects that can be encased in electroplated metal include flowers and insects, leaves and fruit, plaster casts, pottery, textiles, wooden handles, buttons, drinking cups, and so forth.
ADJUSTING THE CUT-OFF TOOL is generally considered one of the most difficult of lathe operations. The tool must be ground properly and adjusted to exact lathe center height. At the left is shown a quick and accurate way of doing this. A machinist’s rule is used to measure up from the ways to exactly the height of either center, and the tool is set at precisely that height.
NEW CUTTINF OILS adapted to specific machine operations now eliminate in large part older trial-and-error methods of prescribing proper grades. They permit faster speeds and new methods of tooling, closer tolerances, and increased use of alloy steels with lower machinability ratings than metals normally used.
GROTESQUE WELDING MASKS. Fighting planes painted to resemble sharks may have inspired these welders at North American Aviation to apply war paint to their helmetsߞ or perhaps it’s an old Indian custom they’ve adopted to scare the Axis. Other workers have followed suit, and many weirdly decorated masks glower from the walls of the plant’s locker rooms.
SPECIAL accessories and jigs greatly increase the usefulness of the circular saw. Often they enable it to double for machines that may be lacking in the home workshop. Many useful attachments can be made of wood in the shop. Others must be purchased, and among the most important of these are planer saws and dado heads.
Tenoning Jig on Miter Gauge Provides Parallel Heads
THIS jig permits the miter gauge to be kept in one groove for tenoning, as the working edge of the stock bears against a second parallel guide for cutting the opposite cheek. Not only does this prevent any misalignment of shoulders due to the stock being not quite parallel, but it also allows tapering stiles to be tenoned.
CAN we have two-rail operation and automatic signaling, too? Only a few years back the answer would have been a flat “no.” It was pretty well known, of course, that the trick was not altogether impossible—two-rail pikes, completely signaled, were already in operation.
SKIS often present a difficult storage problem be cause of their length and shape. Although some experts prefer simply to tie them together and stand them in a corner, other skiers favor the use of a frame in which the skis can be clamped. Such a frame prevents them from becoming warped in the wrong direction, and so preserves their camber.
TAKE sulphur from the chemist's kit of magic, and almost every manufactured article of daily life would either be altered or cease to exist. Sulphuric acid, which enters into more commercial processes than probably any other chemical, as well as other sulphur compounds, play important roles in many basic industries.
SHORT CIRCUITS and their effects can be demonstrated with two dry cells, a small battery bulb, and a battery-testing meter. First, connect the bulb in series with the dry cells and the meter. Now scrape a bare spot on the wires leading to the bulb and away from it.
WITH most factories engaged in war production on a 24-hour schedule, it is more imperative than ever that the electric motors which drive their machinery should be given every care. A motor breakdown may slow up production or even close an entire department for a time.
ELECTRONS, although the smallest particles in existence, are doing a big job in helping Uncle Sam win this war. The problem of producing them and putting them through their paces is a comparatively new branch of science called electronics.
How much do you know about radio? In the sketch of a four-tube A. C.-D. C. TRF receiver above, the artist has made eight intentional errors. Can you find them? As a clew, look for omissions and unnecessary inclusions, and study the parts themselves and their position on the chassis.
A COMPLETE assortment of knob springs, setscrews, dial pulleys, idler pulleys, and drive rubbers is contained in a radio kit, at left, equipped for repairing dials and knobs. The kit is convenient to take on jobs, since it measures only ⅞" by 2¾" by 4¾".
CHANGING PILOT LIGHTS is a simple operation in servicing a small A.C.-D.C. receiver, but be sure that you disconnect the radio at the wall socket—don’t just turn off the switch. A serious short can occur if the pilot-light bracket and holder drop on the tuning condenser or chassis.
A SHARP shell or bit of flint was probably the first knife, so the origin of this tool undoubtedly dates from the dawn of human history. There is no tribe today, even among the most primitive peoples, that does not use knives of some kind. War, hunting, fishing, manufacturing, and the arts have all developed their special types, and at least seven different kinds of steel are used in the manufacture of modern knives.
Dear Workshop Editor: Most home craftsmen need some kind of lumber rack badly. I know I do. Stook left on a damp floor is likely to warp or split, and if it's stacked up in a corner you may fall over it and you always have a hard time finding the piece you want. How about a plan for a simple rack that can be placed against one wall, with some way of keeping different kinds or thicknesses of stock separate?
AN OLD clock or phonograph spring sewn around the waist of your shop apron will eliminate bothersome strings and hold the apron firmly in place. Cut the spring to a length equal to the width of the apron. It is wise to use the innermost part of the spring, since it has more tension, and will cling more closely to the body.
A bag attached at the end of a workbench as shown below is useful for catching sawdust or shavings. A straight piece of wood as wide as the bench, with a curved piece of stock bent around it and screwed fast at each end, forms the bag frame. A burlap bag is fitted into this curve.
HEAVY, unbleached muslin—waterproofed and cut out to cover civilian-defense equipment, such as a mobile fire cart— can also serve as an emergency stretcher. If the cover is wider than a standard 27" stretcher, a third pole pocket should be stitched in.
IF YOUR iron sticks to the clothes, starch or other foreign material has probably collected on the sole plate. Remove this by rubbing the hot iron on a piece of paper sprinkled with salt, as shown above. The metal surface should then be waxed by rubbing it with beeswax or paraffin.
Frame Is Bowed at Center to Pull Wire Screening Taut
WIRE screening can be made taut by bowing the frame ½" or so at the center while the ends of the screening are being tacked on. Place the ends of the frame on sawhorses, and fasten a C-clamp at the center of each side. Lay a sturdy board under the clamps, nail one end to the floor, and attach an eyebolt to the board midway between the two clamps.
Angle-Painting Problems Solved with Adjustable Brush
HERE'S an adjustable-angle brush for painting inaccessible corners on cameras, recording instruments, and similar equipment. Saw off an ordinary brush about two thirds of the way up the ferrule. Drill corresponding holes in the metal ends, and join the two parts with a machine screw and nut, as shown.
Upper sash cords do not often need replacement, but when they do, a stop must first be removed and the lower sash taken out and laid aside. Then pry out the parting bead from the same pulley stile. This member, sunk in a groove, is often held by a nail near the center, and if the runs are painted, may be stuck tight.
HOW CONDENSATION CAUSES A HOUSE TO DETERIORATE . . . AND WHAT YOU CAN DO TO CORRECT IT
VITAL SPOTS IN YOUR HOME WHERE CONDENSATION CAN CAUSE COSTLY DAMAGE
IN THOUSANDS of loyal American homes, sabotage is going on. This sabotage is unintentional, but scarcely less severe than if it were enemy inspired. When paint blisters and peels or brown stain appears on the outside walls of a new home—look for sabotage.
AN EASY way to insure giving star drills the proper amount of rotation with each hammer blow, in order to produce the maximum depth of cut, is to paint the shank with alternate vertical stripes of black and white. This will provide a means of telling how much the drill is turned each time.
PIECES of an old phonograph or clock spring cut about 6" long are useful for dressing grinding wheels. Hold such a piece about 1" or less from its tip in a pair of pliers and place it against the revolving wheel, making sure your eyes are adequately protected.
WHERE a house is surrounded by large trees, the gutters and leaders are likely to become clogged with wind-blown leaves. This difficulty can be overcome by covering the gutter with ¼" galvanized wire mesh. If the gutter is of the metal type, cut the mesh into strips ½" wider than the distance from the outer top edge of the gutter to the cornice board and turn the extra ½" to form a right-angle lip.
COMPRESSION and expansion springs can be wound on a rod with the help of a notched pipe having an inside diameter the size of the spring to be made. Clamp the end of a length of piano wire with the rod in a vise so that the wire is held at an upward angle.
