IN MY last article I left you more or less “up in the air.” That is to say, I traced the broadcasting process from the throat of the singer or the strings of the musical instrument to the aerial of the transmitting station.

M. B. Sleeper
ONE of the most interesting phases of radio development, about which the public still knows very little, is the use of extremely short waves for sending and receiving by radio telephony and telegraphy. A short time ago radio engineers considered wave lengths below 600 meters of very little value for long-distance communication, but today the reception of Poldhu, the high-power station at Cornwall, England, on a wave length of 90 meters, is not at all unusual.

A CLAMP that saves time and labor in locking up foundry flasks is illustrated. This clamp can be used to advantage on any flask, but is especially applicable to long and narrow flasks. To demonstrate the efficiency of this design, the clamp was applied to the trunnions B of a 2 by 8 ft. flask, which previously had been set up with six of the old style clamps, shown at C. By using one clamp at each end, driven tight with a 5-lb. hammer, the small clamps became so loose that they and their packing pieces D could be removed easily with the hand.

MODERN machine work and automobile repairing require the use of accurate measuring instruments, particularly micrometers, for the production of satisfactory work. The expense of a complete set of micrometer calipers, covering all the sizes encountered in machine work and motor servicing, is usually prohibitive in the small shop, and consequently makeshift methods are used, with unsatisfactory results.

AN ADJUSTABLE mandrel useful for work that must be turned on centers and does not require a high degree of accuracy, is shown in the accompanying illustration. This tool does away with the necessity of turning up an endless number of temporary mandrels for oddsized and odd-shaped holes, for which it is not possible to use standard mandrels or even expanding mandrels, if they are available, which often they are not.

A QUICK-ACTING chuck for holding one threaded end of a stud while threading the other end can be made as shown from a piece of iron or steel. The piece is threaded through the center to receive the stud and then cut in two. These parts are drilled and tapped for three studs, which are to hold them together, and countersunk from inside to form pockets for the springs that serve to spread them apart.

IN THE small shop the need for another lathe often is felt. As a rule, a drill press is to be found idle, and this can be used for certain classes of work in connection with the jig that is illustrated below. The size of this jig, which is designed especially for facing operations, is governed by the drill press on which it is to be used, therefore no dimensions are given for it.

IN THE building of any machine that requires a water vat or tank, a galvanized sheet-iron tank is generally the most practical kind to use. A wooden tank will warp and leak, while a metal tank has neither of these faults. The same holds true in regard to watering troughs, tanks for gravity water systems, and other tanks necessary on a farm.

MOISTURE in the air often condenses on cold-water pipes that run through a warm room. This difficulty sometimes may be overcome simply by giving the pipes or other metal surfaces three or four coats of paint. A much more certain method, according to Henry A. Gardner of the Scientific Section of the Paint Manufacturers’ Association of the United States, is the following: Give first a priming coat of metal protective paint, then a coat of spar varnish containing whatever color pigment is desired.

How to Time Auto Engine Valves
[no value]

Ray F. Kuns
THERE are two distinct phases in the timing of an automobile power plant. Properly speaking, engine timing is the timing of the camshaft to the crankshaft so that the valves will open and close in time with piston travel. Also in time with the valve opening and piston travel, must be the opening of the contact points in the breaker box, which will insure a spark being delivered at the right instant; this is ignition timing.

G.L.
MANY of the usual methods of making a brazed or soldered union in steel or brass tubing have the fault of being weak at the junction. Threading and coupling with a union weakens the tubing because the thread cut reduces the diameter of the threaded portion of the tube, and a loose sleeve over the ends of the tubes cannot be brazed or soldered with assurance that the metal will bind under the sleeve.

THE oilstone is one of the most essential and often most abused tools in the home workshop. I have seen stones with a surface thoroughly glazed through the application of the wrong kind of oil or failure to wipe off the stone after use. To keep your stone in condition, use a good grade of mineral oil, wipe the stone off when you are through with it, and keep it in its case or at least in a place where it will be free from dirt.

WORN-OUT vibrator bridges of Ford coils can be had for the asking at any garage and often prove handy around a shop. They serve as small braces on machinery or fittings, as spacers between parts, and the like. Two other uses are shown. A vibrator bridge, a razor blade and two small bolts make an excellent scraper for removing paint from glass and similar purposes.

AN OLD writing-desk that had outlived its usefulness was converted into the radio cabinet shown simply by removing the pigeon holes and shelves from the interior. There are several advantages in a cabinet of this type besides its cheapness and the fine appearance of the old walnut.

NOW and again when wandering in the woods or along the road, knubby pieces of tree limbs are found, so odd that they tempt one to take them home. Some of them may be cut into unique and attractive paper knives. Usually a knubby end may be trimmed a bit to form the handle and a projecting limb shaped like a knife blade.

"WELL, settled that’s for the winter,” a friend of mine remarked with visible relief as the last bucket of a 15-ton consignment of coal rattled down the chute into his basement. “Last year I bought only 10 tons, thinking that would do, and had a hard time getting five additional tons when I found I needed them. I am taking no chances this fall.”
