The temperature of the water at the commencement of the experiment was 60° Fahr., and after two horses had turned the lathe for 22 hours the water boiled.
In working amber, it is turned on the lathe and polished with whitening and water or with rotten stone and oil, the final lustre being given by friction with flannel.
The sphere is then coated with plaster or whiting, and when it has been smoothed on a lathe and dried, the lines representing meridians and parallels are drawn upon it.
The spindles to which the wheels are attached revolve in a lathe worked by a foot treadle.
A crystal lens, turned on the lathe, was discovered by Layard at Nimrud along with glass vases bearing the name of Sargon; this will explain the excessive minuteness of some of the writing on the Assyrian tablets, and a lens may also have been used in the observation of the heavens.
Some lignites are, however, quite as brilliant as anthracite; cannel and jet may be turned in the lathe, and are susceptible of taking a brilliant polish.
Cannel is more compact and duller than ordinary coal, and can be wrought in the lathe and polished.
The five modern lathes (Aylesford, St Augustine, Scray, Sheppey and Sutton-at-Hone) all existed in the time of Edward I., with the additional lathe of Bedding, which was absorbed before the next reign in that of St Augustine.
(2) In the Ransome system round bars are rejected in favour of square bars, which have been twisted in a lathe in "barley FIG.
Hence a machinist can cut steel or iron nearly six times as fast with a lathe tool of this steel as with one of carbon steel, because with the latter the cutting speed must be so slow that the cutting tool is not heated by the friction above say 250° C. (482° F.), lest it be unduly softened or " tempered " (§ 29).
Temporary cement for lathe-work, such as the polishing and grinding of jewelry and optical glasses, is compounded thus: - rosin, 4 oz.; whitening previously made redhot, 4 oz.; wax, 4 oz.
A sheet of metal set revolving at a high speed in a lathe is bent over into cup-shaped forms, with numerous mouldings, by a blunt hardened tool.
To separate the tobacco leaf from the stems, to remove the overlying soil from a mineral deposit before opening and working it, to turn a gun-barrel in a lathe, &c. In architecture, a "strippilaster" is a narrow pilaster such as is found in Saxon work and in the Italian Romanesque churches.

The New English Dictionary suggests a connexion with "lathe," a term which survives as a division of the county of Kent, containing several "hundreds."
A common arrangement for driving a lathe spindle, in either direction at several definite speeds, is to provide a countershaft on which are mounted two fixed pulleys and two loose pulleys to accommodate two driving belts from the main shaft, one of which is open and the other crossed.
Motion in either direction is thereby obtained, and a considerable variation in the speed of rotation can be obtained by providing a cone pulley on the countershaft, which drives the cone pulley secured to the lathe E FIG.
The dimensions of the pulleys are generally so arranged that the return motion of the lathe spindle is faster than the forward motion.
He was himself always occupied: writing his memoirs, solving problems in higher mathematics, turning snuffboxes on a lathe, working in the garden, or superintending the building that was always going on at his estate.
The prince was working at the lathe and after glancing round continued his work.
The large table covered with books and plans, the tall glass-fronted bookcases with keys in the locks, the high desk for writing while standing up, on which lay an open exercise book, and the lathe with tools laid ready to hand and shavings scattered around--all indicated continuous, varied, and orderly activity.
After a few more turns of the lathe he removed his foot from the pedal, wiped his chisel, dropped it into a leather pouch attached to the lathe, and, approaching the table, summoned his daughter.
And the lathe? asked Prince Andrew with a scarcely perceptible smile which showed that, in spite of all his love and respect for his father, he was aware of his weaknesses.
"The hours are the same, and the lathe, and also the mathematics and my geometry lessons," said Princess Mary gleefully, as if her lessons in geometry were among the greatest delights of her life.
When Princess Mary went to him at the usual hour he was working at his lathe and, as usual, did not look round at her.
