The distance from tank to the farthest hydrant being so short, they get the pressure due to this head at the hydrant, when playing 2-inch, or 1-1/8-inch streams, with short lines of 2½-inch hose; this gives fair fire streams for a town with few if any buildings over two stories high. It is estimated that this mill is pumping from 30,000 to 38,000 gallons on an average every twenty-four hours.
The plain stick which small children flying small kites on short strings find sufficient for winding their twine on is far too primitive a contrivance for dealing with some hundreds of yards, may be, of string. In such circumstances one needs a quick-winding apparatus. Select a sound piece of wood, 3/8-inch thick, 5 inches wide, and about 1 foot long.
Another time the descent of an 8-inch saved the amour-propre of a worried second lieutenant, who, after jockeying with his angle of sight, had got into abject difficulties with his range and corrector.
She was armed with several Gatling and Nordenfeldt guns, three 12- pounder breech-loaders, six 3-pounders, and one 8-inch breech-loading Armstrong gun, throwing a projectile weighing 170 pounds, which was mounted forward; and, immediately upon Jim's command her whole broadside crashed out, raking the foolhardy steamer from end to end, and making her fairly reel under the impact of the iron shower.
Through their exact centres drill 1/8-inch holes, and cut the pieces squarely in two across these holes. The sawed faces should be filed down to a good fit and soldered together. Now drill holes of the size of the pins, using what remains of the holes first made to guide the drill. The bolt holes are drilled next, and finally the holes for lubrication and those to take the rods.
As she swung around, with her stern directly toward the Olympia, an 8-inch shell struck her squarely, and the explosive must have travelled directly through the ill-fated craft until it reached the after boiler, where it exploded, ripping up the decks, and vomiting forth showers of iron fragments and portions of dismembered human bodies.
Jim ground his teeth as he saw the terrible execution wrought by the Union's broadside; and, exhorting his men to keep cool, ordered them to load and fire as fast as they could. Once more the cruiser's 8-inch gun roared out, sending its vengeful messenger shrieking toward the corvette.
The power cylinder is a piece of brass tubing 2 inches long and of 7/8-inch internal diameter. The piston is of 7/8-inch tubing, fitting the cylinder easily, and thick enough to allow a shallow packing recess to be turned in the outside. Brass washers turned or filed to size form the ends of cylinder and piston.
The fuel to run these drills is conveyed by small pipes from adjoining wells. An 8-inch hole having been bored to a depth of about 500 feet, a 5-5/8 inch wrought-iron pipe is put down to shut off the water. The hole is then continued 6 inches in diameter until gas is struck, when a 4-inch pipe is put down. From forty to sixty days are consumed in sinking the well and striking gas.
File and rub the sides until no projections are visible. Then drill twelve 3/32-inch holes right through the three parts. After separating them, the holes in the walls and what will be the cover must be enlarged to an easy fit for 1/8-inch bolts, and the valve plate tapped. Now drill 3/16-inch holes centrally through the ends of the walls for the valve rod.
