	Rodman's Great Guns
		Of one pair, the gun cast by Rodman's principle was fired 1,500 times; its counterpart, cast on a solid core and cooled externally, burst on the 299th shot.
		The 15-inch Rodman gun was 15 feet, 10 inches long, with a bore length of 13 feet, 9 inches, or 11 times caliber, a good deal shorter than the general rule.
		Rodman's guns proved his theories, and particularly the advantages of progressively burning powder, but the 20-inch gun was still too big to be a really effective weapon.

	Thomas Jackson Rodman
		Rodman was confident his process would cause the cooling metal to contract toward the bore and increase the density of the metal where it was most needed.
		The Rodman gun was adopted as the standard heavy gun for coastal artillery and in lighter versions for fortress and siege use.
		Rodman felt, or at least claimed (he seems to have limited his ambitions rather reluctantly), that a 20-inch gun firing a half-ton shot would be quite big enough.

	Mammoth Guns
		Thomas Jackson Rodman graduated from the military academy in 1841 and was assigned to the Ordnance Department at Allegheny Arsenal in Pittsburgh.
		Rodman obtained permission from his superiors to apply for a patent for hollow casting guns and arranged for the Fort Pitt foundry to cast and test his cannons.
		Rodman developed a knob that was almost as large as the base of the piece and had only a narrow grove to accommodate lifting tackle.

		CAPTION: "The famous Rodman Gun was one of many produced during the Civil War by the C. Knapp Foundry, later the Fort Pitt Foundry (now Mackintosh-Hemphill).
		Thomas J. Rodman, commander of the Allegheny Arsenal, it was the largest in the world at the time (80 tons).
		Rodman achieved fame during the Civil War for his designing of a large cannon, which is believed to have deterred France and England from entering the war on the side of the Confederacy."(9) PHOTOGRAPHER: [B. H.] Dabbs.

	Basic Facts Concerning Artillery
		Rifled weapons had to be stronger than smoothbore because a greater stress was inflicted on the gun by a tighter seal (less windage) necessary for the projectile to take the rifling, resulting in vastly greater pressures in the breech to overcome the friction between the projectile and the rifled bore.
		His process, which caused less stress on the gun during casting thereby preventing cracks from forming, was a success and the Columbiad became widely known as a Rodman gun.
		This gun is sometimes erroneously referred to as a "Rodman." The process used by Thomas Rodman in casting the Columbiads was not used in producing the wrought iron barrel of the Ordnance gun.

		The Rodman gun on the other side was a manufacturing process rather than a cannon, developed by Thomas Rodman in the mid-1840 for casting large iron cannon.
		Rodman's process had the gun cast about a hollow pipe in which water was pumped during the cooling process while the outer part of the casting was kept hot by live coals.
		These guns were used in coastal defenses and fortifications and were capable of firing a large shell or ball up to several miles and were excellent defensive weapons.

	Artillery Encyclopedia - Rodmans and Confederate Columbiads
		Rodmans were cast using the Rodman process of internally cooling a hollow core (now referred to as "wet chill"); Confederate Columbiads were poured solid.
		The Rodman profile is a sweeping continuous curve, in all sizes, with not even a minute cylindrical portion at the reinforce.
		The Rodman bore bottom is an extended hemispheroid; the bore bottom of the Confederate Columbiad is a hemisphere.

		Guns and gun platforms on third level were removed, and new emplacements for larger guns begun on the north, east and west faces, with parapets and magazines protected by sod-covered sand.
		The gun casemates on the first and second levels would have been framed in and doors, windows and stoves installed to serve as quarters for the enlisted men, but the fort was never permanently garrisoned.
		In 1864 there were 26 smooth bore, muzzle-loading 10 inch Rodman guns mounted on the first level and three rifled, muzzle-loading Parrott guns mounted on the third level.

	The Cannon of Angel Island
		The Island’s “temporary” gun batteries continued to be considered part of the Bay’s military defenses during the 1870’s and 80’s, despite being seldom used and poorly maintained.
		If the target was within 2.7 miles a 10” Rodman could instead lob a 101-pound hollow iron shell that was packed with gunpowder and set to explode a few seconds after it was fired; the detonation being controlled by a time fuse set in the shell.
		The guns were ultimately moved to Point Blunt and a variety of other cannon were mounted at the Camp Reynolds water battery in the years after the Civil War.

		With Rodman's gun, the muzzle-loading smoothbore was at the apex of its development.
		It was a demonstration of using great masses of guns, bringing them quickly into action to destroy the hostile artillery, then thoroughly "softening up" enemy resistance in preparation for the infantry attack.
		In seacoast batteries were 8-, 10-, 12-, 14-, and 16-inch guns and 12-inch mortars of the primary armament; intermediate rapid-fire guns of 3-, 4.72-, 5-, and 6-inch calibers; and 6- and 15-pounder rapid-fire guns in the secondary armament.

		Called "Quaker guns" because they couldn't hurt a fly, the camouflaged logs were used by wily Confederate commanders to exaggerate their strength or mask a retreat.
		The fake guns were used first and most effectively in Northern Virginia, where the logs -- and real guns -- discouraged Gen. George B. McClellan and Union forces from attacking deep into Virginia and threatening the key railroad junction at Manassas.
		Herzog said the Mayfield Quaker gun is the only one of its kind on display as far as she knows.

		In February 1844, Rodman was one of several officers and dignitaries who witnessed the firing of the "Peacemaker," a large gun aboard the U.S.S. Princeton in the Potomac River near Washington, DC.
		Rodman developed a method of casting the gun barrel around a hollow core or pipe, sealed at the bottom.
		Rodman's new process revolutionized coastal armaments in the U.S. These smoothbore guns lost favor, however, as the superiority of rifled barrels became evident against older forts.

		The Rodman guns were manufactured by an improved process that allowed a heavier powder charge and a larger caliber than the previous Columbiads.
		In the 1870's, three 20-inch (508mm) Rodman guns (originally intended for the never-completed super-Monitor "Puritan") were placed in New York harbor forts.
		The railway guns were 8-inch (203mm) and 14-inch (356mm), with some 12-inch mortars.

		The gun was erected by Thomas Phillips and Son of New Haven on a base of huge dark gray Quincy granite blocks purchased from the City of New Haven.
		In service Rodman guns did have wheels, but the I beams are not a typical mount, and probably were introduced as part of the support structure in 1911.

	April, 96 Tweak
		However, some of the bad rap laid on the gun wasn’t deserved—witness that it has been the country’s primary battle rifle for more than two decades.
		The biggest problem stems from the gun’s handguard design—the sling swivel is attached to the handguard front cap, which is attached to the barrel.
		Placing varying tension against the sling swivel, as is done in position-style shooting, changes where the barrel looks as the bullet leaves the muzzle, causing the gun to shoot erratically.

		As to the phenomenon known as the "ashy light," it is explained naturally by the effect of the transmission of the solar rays from the earth to the moon, which give the appearance of completeness to the lunar disc, while it presents itself under the crescent form during its first and last phases.
		The Rodman Columbiad threw a shot weighing half a ton a distance of six miles, with a velocity of 800 yards per second-- a result which Armstrong and Palisser have never obtained in England." "This," replied Barbicane, "is, I believe, the maximum velocity ever attained?" "It is so," replied the general.
		This contract, executed in duplicate, was signed by Barbicane, president of the Gun Club, of the one part, and T. Murchison director of the Coldspring manufactory, of the other, who thus executed the deed on behalf of their respective principals.
