Sir: As a rural mail carrier, I have a boner to pick with your mostly excellent magazine. That’s your suggestion under “Keeping the Home Shipshape” in November, page 170, for making a mailbox flag automatic. Your scheme is against Post Office Dept. regulations, under which the signal flag is supposed to be in lowered position except when the patron has placed mail in the box for the carrier to collect.

IF YOU are somewhat beyond the "normal" TV range and your pictures are weak... If one station that you especially want comes in poorly... If you are near a transmitter but can’t have a roof-top antenna... ...You should try a television booster.

LOW-COST tinning of metal surfaces is a simple matter with this tinning paint. After old paint or other coats are removed from the metal, a coat of the tinning paint is brushed on. Heat is applied—usually with a torch—until the paint bubbles and turns brown.

How You Can Photograph the Fights Via Television
Like a ringside cameraman, you must anticipate the action. For best results, shoot at 1/50 sec.—and overdevelop.

NEXT time you watch a prize fight on TV, keep one eye on the edge of the ring, and you’ll occasionally see a newspaper photographer push his camera under the ropes to snap a picture. What these men do at ringside, you now can try at home—on TV. The pictures you get may not have all the zing of ringside shots but they’ll be surprisingly good.

FIVE cents worth of hardware is enough to make a pickproof magnetic lock for any wooden door or drawer. It will baffle anyone unless he has a magnet and knows just what to do with it. The latch is locked when two metal balls wedge metal vanes connected to its pivot, keeping the latch from rotating.

HOW can I get started in outboard racing? How much will it cost? What kind of a hull do I need? What kind of a motor do I need? Put these questions to any 10 drivers of racing outboards and you’ll probably get 10 different answers. But here’s one answer—one that you can do something about without laying out your life’s savings for a racing outfit.

IN THE darkest, coldest room in our city home stands a box 16" high and 25" square, shaped somewhat like a pirate’s treasure chest. Inside it, many seedlings and cuttings are receiving their nourishment from chemical nutrients and their life-giving light and heat from a 20-watt fluorescent "sun."

Drilling Radial Holes. Your lathe can be used to index holes on a circumference and drill them on a true radius. Just mount a hand or breast drill on the compound rest as shown. With a different mounting you could also use an electric drill. Disassemble the drill and mount frame between centers on the hole through which the spindle fits.

Within the past year there have been many conflicting recommendations on how often to change oil. One magazine article suggested that every 4000 miles is often enough under normal conditions. The point most often missed is that the average car owner does most of his driving between home and work.

Grassland farming means better pasture grasses and legumes, more forage production, utilization of grass silage. But animal droppings on pastures have caused headaches. Plant life under the droppings tends to grow rapidly and form clumps, making an uneven surface that breaks implements.

DEADLIEST DRIVING in the world is done in Bombay, India, according to a world traffic survey made by the Danish Government. The annual fatality rate there is 769.66 per 100.000 cars and trucks. In Los Angeles (which has more cars per family than any other city in the world), the annual death rate in traffic accidents is only 27.86 per 100.000 cars; and in Milwaukee (the safest city in this respect) it is only 22.06 per 100,000 cars.
