One of my pet peeves is the hokum Detroit puts out on auto lubrication. Richard Day's "A Home Auto-Lube Center" [Feb.] perpetuates these fraudulent statements. He says about transmissions and differentials "most cars use the same gear lube for life—usually if no drain is provided, no lube change is called for.

It was probably inevitable; the big boom in off-road vehicles has spurred a reverse boomlet. Critics in growing numbers have been teeing off on trail bikes, all-terrain rigs, dune buggies, snowmobiles, and other off-road vehicles, alleging that they cause "a host of environmental problems.

I have a 1970 Ford Club wagon on a 123-in. wheelbase with suspension package "B". Ever since I bought it I have been plagued with front-wheel shimmy at speeds of 25-40 and 70-75 mph. The dealer and factory rep say there is nothing wrong and that I imagine the shimmy.

Would you buy a Pinto or a Vega for $3,000 stripped? Or a VW for $2,800? That's what you'll have to pay in '75 if predictions of top auto executives prove true. John Naughton, manager of Ford, says that safety and smog regulations for 1975 models can raise car prices $700 to $1,000.

Put a lens at one end of a long plastic box and a rangefinder at the other. That's Polaroid's new $20 Big Shot. Nothing moves except the shutter release—and you. You move back and forth, looking through the double-image rangefinder until the two images merge (about 38 inches away, with a couple inches' leeway ).

Do the glowing particles in the heavenly light shows called auroras come from Earth or sun? To find out, a team of Sandia Laboratories scientists will sweep an Arctic aurora with whirling foil collectors borne on a brace of rockets; then they'll recover the foils and analyze the particles embedded within.

How much impact can the human body take? To find out, GM safety researchers hired stunt man Ross Collins to make a series of dives from a 60-foot tower onto a three-foot-thick foam-rubber pad. In all, Collins made 16 jumps. During the highest—from 57 feet— he reached a speed of 40 mph, stopped in a space of about two feet, and withstood a force of 48 gs —higher than previously thought to be safe.

If it's super speed you want, go to Italy. I did, to visit the three Italian limited-production auto makers who have a virtual monopoly on high-performance, production-model touring cars. Italy's highways have no speed limits, and it's possible to travel for hours at average speeds of about twice the maximum legal speed on US Interstate Highways.

Modern materials now let you create custom-designed windows with all the elegance of actual stained glass— at a fraction of the cost, the fuss, the weight, or the fragility of leaded panels. Last month's PS brought you step-by-step instructions for assembling an authentic window by fitting pieces of colored art glass into soldered lead channels.

So there I was heading up to the 110th floor—one hundred tenth—to the very top of Manhattan's new World Trade Center, still being built. I was hurtling skyward in a materials elevator, and through the slats I could see the other buildings of the city slowly shrink.

DC-9
Take an ordinary DC-9, add 16 turbo-tip fans atop a set of special hinged wing flaps, and what have you got? A new idea in STOL planes being studied by NASA. The fans, which increase lift at low speeds, are powered by pressure from air pumps driven by the main jet engines.

RCA's Mini Shaver
$7
You push the switch and C-cell current drives the tiny electric motor. Blades whir and whiskers fall. It's RCA's Mini Shaver, and it provides clean-up shaves for the man on the go. Just five inches long, it costs about $7, including a vinyl carrying case and shaver-cleaning brush.

Westinghouse "idea range"
It cooks, but it keeps its cool. An oscillating magnetic circuit in this Westinghouse "idea range" puts heat directly into the pan. Result? Food gets hot, but the range stays cool— so cool you can cook through paper without singeing it. You can steal this portable safe, maybe, but you can't get it open without destroying the contents. Any attempt to break into it either sprays the contents with indelible blue dye, or burns them up. It's made in Australia.

Sentinel MK 2000
$139.50
If this man’s main parachute doesn’t open properly, the little rectangular box near his open hand, sensing his rate of fall, releases the reserve canopy at 1,000 feet. Said to be the newest, most advanced, fully automatic parachute-release system around, the Sentinel MK 2000 is $139.50 from Steve Snyder Enterprises, Inc., Swathmore, Pa.

Piggyback pair
What’s new in space shuttles? Here’s Convair’s latest design for a booster vehicle. On its back is the orbiter vehicle, which is being designed by North American Rockwell. The pair go out into space together, separate, carry out their missions, then return to earth for reuse.
Steve Snyder Enterprises, Inc.
fwd bug killer
If Honda's new little 600 coupe does as well in the U.S. as their motorcycles do . . . watch out. The details, starting from the front: an air-cooled, two-cylinder, 600cc engine turning out 36 horsepower on regular gas, driving the front wheels through a four-speed gearbox; four-passenger, two-door body with a Gremlin-style rear end treatment, easily loadable through the slanting back window; disk brakes in front, drums in back. Top speed? Somewhere around 75. Mileage? About 40 mpg.
Steve Snyder Enterprises, Inc.
Apollo 15
Astronaut fashions are due for a change. The old suit was cumbersome, hard to don and doff, and not resistant enough to wear. The new one—the A-7L— reduces these problems, and features improved visibility, comfort, and even in-suit water-nourishment provision. Here astronaut Alfred Worden tries it on.
Steve Snyder Enterprises, Inc.
Littlest lamps
That rectangle resting on a piece of newspaper at right is an array of light-emitting diodes, five rows wide, seven rows high. Activating the GE diodes—the world’s smallest lamps—in various combinations gives a total of 64 standard computer characters like the three shown aar right.
Steve Snyder Enterprises, Inc.
Copter cabin
Builders of the Scorpion personal helicopter can now have a fiberglass cabin on their birds, adding just 25 pounds to the weight. The cabin increases air speed and comfort. Rotorway Inc., 14805 S. Interstate 10, Tempe, Ariz. 85281, makes the kit-built chopper and the cabin.

Snapshot TV
Press a button on the Snapshot TV, and 10 seconds later out comes a finished print of the TV picture. The print—two by three inches—is made by contact-printing a dry-silver paper against a special 2 ½-inch cathode-ray tube displaying a negative TV image. The paper is then developed by heat—no chemicals are needed—and emerges finished and dry. The Snapshot TV is by Matsushita Electric, makers of Panasonic electronic equipment.
Steve Snyder Enterprises, Inc.
Headliner lighting
Drive a lot at night? The electroluminescent panel on the Pininfarina "Modulo" dream car might interest you. It runs off the car battery, takes up only ¼-inch of headroom, and provides soft light that won't disturb your driving. It'll work in present-day cars, and a patent is pending.

Handy 3-pack
Looking for a 3-pack of Cadillacs? There are several on the flat car above, and another is being swung into place. The "pack," a 15-foot-high steel container, is a new idea in shipping autos. It protects them from weather, dirt, and vandals while on the way from factory to dealer. A safety cushion for backseat passengers, a head restraint for front-seat passengers—that's the idea behind the bulbous addition to the front seatback above. Chrysler's developing the cushion as a part of their crash-protection program.

Camp R Boat
Driving your pickup camper, trailing the Camp R Boat, you arrive at the water. Using a special winch, you move the camper box from pickup to boat. Launch the boat—and there you are on your own houseboat! Camp R Boat Corp., 1080 Estes St., Lakewood, Colo. 80215.

Why carry your boat to the water when you can roll it? Dinghy Dolly is a pair of wheels that strap to your boat in seconds for launching and lugging, unstrap in seconds once you're afloat. Mamco Mfg. Co., 1427 N.W. 49th St., Seattle, Wash. 98107, makes it.
Glastron
Homestrand 406
$166
Run it on electricity when you're connected to a power source, or burn alcohol when you're far from shore. Either way, Kenyon Marine's new Homestrand 406 can do your cooking. The electric controls are mounted at the side of the flush-mount stove; the alky controls are in front. Price? $166.
Glastron
The fiberglass Minifish
$400
What’s smaller, lighter, and easier to handle than a Sunfish? Minifish, little sister in the Alcort family of boardboats. The fiberglass Minifish weighs 75 pounds, is 11 feet 9 inches long, has a 65-square-foot dacron sail, and sells for under $400. Go ahead, stand up to cast— your canoe won’t tip. At least it won’t if you install a pair of Grumman’s foam outrigger pontoons. With the canoe level, the pontoons are just above the water for easy paddling. They'll fit any Grumman canoe from 13 to 20 feet.

Tough repair tape
$2 to $5.50
It’s called Book Tape because it used to be sold only to libraries. It’s a permanent, transparent, self-stick polypropylene that’s ideal for mending worn books and record albums. 3M makes it in four widths to 4 inches. $2 to $5.50 at stationery stores.
Remington
Self-mixing server
$20
You’re an instant bartender-tackling exotic drinks like Mai Tais and Pink Ladies— with this flip-lid tankard. It’s part of an electric bar blender. You pour in up to 20 ounces of ingredients while it’s on its pedestal, hold a pressure-activated switch for the right length of mixing. By Remington; $20 at stores.
Remington
Minit Foam
This two-can package makes it easier to mix urethane foam for aerosol application. You place the needle valve of one can into the opening of the other, wait for gurgling to stop, insert spray tip supplied, shake—and you have five minutes to apply the Minit Foam.
Remington
Touch-n-Glue tubes
Flexible plastic teeth have been added to the tip of Touch-n-Glue tubes to make small jobs even quicker and cleaner. You can brush out a thin coat while squeezing-all with one hand. Cap now has a piercing device that reseals the tube between jobs.
Remington
Self-stick hook strip
$4.99
Insert regular perfboard hooks in the plastic bubbles of Peg-Tape and you can hang items anywhere. The flexible tape even wraps around posts. Wet the back and press it in place. For $4.99, Handi-Helpers, Box 69, Collingswood, N.J. 08108, sends three cuttable four-by-12-inch panels plus 24 assorted hooks.
Remington
Slim air cleaner
No space for an electronic air cleaner for your forced-air heating and cooling system? Can you spare eight inches? Westinghouse’s VF Precipitron models are under that in width, and only 13 to 18 inches tall. One-piece construction is adaptable for horizontal or for vertical flow.
Remington
Underslung drawers
You can now hang drawers beneath any table top, workbench, or shelf with a pair of 344 slides that screw to the underside.

Remington
Popper stopper
How many times have you poured half a can of soda down the sink because it was more than you wanted and there was no way to save it for later? Now there is—a re-usable stopper that reseals a pull-tab can. Stopper, Box 44, Chula Vista, Calif. 92012.

Pistol-grip painting
$2.50 to $5.50
This month's "why-hasn'’t-someone-thought-of-it-before" award goes to Percy Brittain, Inc., 4445 Kincaid E. Rd., Warren, Ohio 44481, for banishing painter's cramp. Pistol-grip brushes with nylon bristles in threeor four-inch size (shown) range from $2.50 to $5.50.

$60
Doorway arches from 30 to 44 inches wide are simple to construct in either wood or masonry with this adjustable steel form. Eleven arms adjust from 15 to 22 inches in length to shape round or pointed arches. $60 from Munson, 10743 May-field Rd., Chardon, Ohio 44024.
Percy Brittain, Inc.
Shatterproof blade
Try looping a high-speed-steel hacksaw blade like this and it shatters—just as it does in your saw frame, when forced to flex too much. Carbon blades, by contrast, seldom break, but dull quickly. Solution? Weld a high-speed cutting edge on a shatterproof back. Olympia Bi-Metal blades by Contour Saws, Des Plaines, III.
Percy Brittain, Inc.
Re-usable blind rivet
The aluminum stem of Alcoa’s Ram fastener wears a nylon locking jacket. You just drill a hole through parts to be joined, position tip of stem, and press into place with thumb. Slotted end of jacket expands, holding parts together. Grooves in the jacket head permit removal, later— and fastener can be re-used.
Percy Brittain, Inc.
Mini belts
A line of miniature 40 diametral-pitch belts is now available from Sterling Div., Designatronics, 55 So. Denton, New Hyde Park, N.Y. 11040. They come in 33 lengths and in widths from ⅛ to 5/16 inch.

If you're shopping for lots of cooling power on a tight budget this summer, there's a rapidly expanding line of high-Btu air conditioners just for you. With a 24,000-Btu multiroom unit, you may be able to cool your entire house for under $400. Central air conditioning might provide more benefits [see "The Case for Central Air Conditioning," PS, May '70], but it can cost you several times that $400 if it involves much installation work.

One recent Monday morning, our class of nine dealers and technicians gathered in the lecture room at this highly regarded school.

FRED WOJCIK
Many of us small-car buffs have felt left out of the camping scene. Even with our limited horsepower, we should be able to tow at least minimal gear for cross-country touring. You'd think the tent trailer would be a natural for small cars, but most commercial models are too wide, too hefty, and have too great a tongue load for our Bugs and Gremlins and Crickets.

Hand anyone an ordinary compass and straightedge and he can doodle up a variety of designs. But the trick is to make these tools produce practical solutions to home-shop problems. Being more professional than the doodler simply means knowing something about the kinship between geometrical forms.

Figure it out for yourself: Apply prefinished vertical-groove paneling on the walls of a stairway to wainscot height and you normally wind up with a lot of waste. You get only a four-foot run out of a four-by-eight panel. The waste pieces, though sizable, have the wrong angles or are too short for use as the next section or opposite side.

Built-in shelving enhances the utility of a home, but why leave it behind if you move? This simple design solves the problem. A hidden wedge in the top press-fits the unit between floor and ceiling. Measuring approximately half the desired shelf width, the wedge slides from a retracted position to one that is parallel with and about 1" above the sides of the ceiling box.
