THERE ISa smug and satisfied feeling, despite the awesome implications of the A-bomb, that we made great scientific strides during the war. That atom-smashing was certainly something, wasn't it? And don’t forget radar, loran. guided missiles, the proximity fuse, and all the other devil's gadgets that have been hitting the headlines.

Sir: Several years ago an article on television started me wondering how the radius of the television transmitter could be substantially increased. I conceived the idea that stratosphere balloons located throughout the country could be used, with automatic relay installations in the gondolas.

BY DECEMBER, 3,500,000 American families will have no homes of their own. Two thirds of them probably will be veterans. For all, home will be a bedroom in someone else’s house. More families will be doubled up than there are in New York, Chicago, and Philadelphia put together.

TWO engineering features that make the new Kaiser car a radical departure in automobile design are front-wheel drive and torsion-rod springs. Both have been proved out thoroughly in Army equipment, from the jeep to the Pershing tank. While both have been taken over almost bodily from military cars, some alterations in design were necessary, of course, in adapting these features to modern passenger-car use.

A MAN who wouldn’t give up after everyone else had failed has produced what bowlers the world over have wanted ever since the game was invented-—a machine that will “spot” tenpins on the alley. With Fred Schmidt’s automatic pin spotter, a bowler can spill the maple 24 hours a day if he wants to, and the machine will set ’em up, rake off the deadwood, and return the ball with the regularity of the tides.

Fundamental scientific research is at a standstill in America. That is the harsh fact of a matter that has been hushed and avoided too long. The cause is a literal interpretation of democracy that has yanked 150,000 men out of scientific studies to make a scant two percent of the total armed forces.

A SECOND weapon almost as terrible as the atom bomb was ready at the American hand when the Axis capitulated— bacterial warfare. A two-edged weapon, it might have prevented its users from occupying conquered countries for years—for plagues and pests recognize no surrender.

USING vastly more power than was ever utilized to probe the sky for enemy planes, man beamed radar waves at the rising moon a few minutes before noon on January 10, 1946—and in 2.4 seconds received a feeble response for the first time. In loudspeakers it was a 180-cycle note, a little higher in pitch than the hum of a poorly tuned home radio; on oscilloscopes it was a jagged hummock of light.

TAKE four masts about twice the height of telephone poles and string a few hundred feet of cable between them, and you have an airport in mid-air on which an airplane can take off and land without touching the ground. Here is a portable airfield that weighs only 6,000 pounds; it can be packed up and carried in another airplane, dropped by parachute, and set up for business by a six-man crew in a couple of hours.

THE bowyers and fletchers who made the weapons for Robin Hood and his Sherwood Forest sharpshooters would be astounded at what has happened to their ancient craft. For hewing the bow from the stave and feathering the arrow to fly true have gone on a mass-production basis to satisfy the modern interest in archery.

CYLINDRICAL cardboard boxes in which table salt is sold will serve as convenient containers for storage of many small objects in the garage and workshop. The boxes can be filled with a funnel, and the metal spout makes it easy to remove just a few parts when they are needed.

EVERYBODY wants to own a boat, judging from the entries in our boat contest. Designs were received from all over the country, from Canada, and from Europe. There were boats made of wood, plywood, molded plastics, and steel. Utilitarian houseboats, graceful sailboats, Diesel and gasoline-powered motorboats, and jetpropelled high-speed hydroplanes all had their adherents.

SERVING a double purpose in the workshop, this illuminated magnifier can be used on a bench stand for delicate hand work, or attached to a jigsaw or other tool so that fine markings may be followed accurately and without eyestrain. The lens used here was salvaged from an old reading glass, but any old or new lens approximately 4" in diameter and giving suitable magnification will serve for this purpose.

With the end of war production and the probable release of numbers of surplus lathes, some in sizes suitable for home use, that day may be near for many amateur machinists.

HANGING DARKROOM

RICHARD B. LEWIS
IF YOU think that floor space is lacking in your present quarters for a permanent darkroom, perhaps you can profit by my experience. I managed to materialize my darkroom out of thin air—by hanging it in the back of a two-car garage. In the typical double garage, there is space for a darkroom more than 10' long and almost 6' deep, provided that it is built with its floor over the space normally occupied by car bumpers, and with its workbench overhanging the car hoods.

DEPENDABILITY is a major feature of the flash-bulb battery box above. Built of scrap wood, it contains two No. 6 dry cells, furnishing 3 volts in series, which are wired to double outlets at both ends of the box. The same cells have given good service for nearly a year, and, on occasion, have been used with more than 40' of wire and two reflectors.

While one photo above shows a tankperiscope prism being cut with a power hacksaw, the job might also have been done with a hand hacksaw. You will need only a little aluminum-oxide or silicon-carbide abrasive (100 to 120 grit), some turpentine, and a worn hacksaw blade.
