Pin Construction
Bowling pins are constructed by gluing blocks of rock maple wood into the approximate shape, and then turning on a lathe. After the lathe shapes the pin, it is coated with a plastic material, painted, and covered with a glossy finish. Because of the scarcity of suitable wood, bowling pins can be made from approved synthetics. Currently there are synthetic pins sanctioned for play in five-pin, duckpin, and candlepin. There is one synthetic ten pin model approved by the USBC. When hit by the ball, synthetic pins usually sound different than wood pins.
Juggling clubs could be mistaken for bowling pins due to their similar shape. The two differ greatly in construction and weight.

Famous quotes containing the words pin and/or construction:
“It is not, truly speaking, the labour that is divided; but the men: divided into mere segments of men—broken into small fragments and crumbs of life, so that all the little piece of intelligence that is left in a man is not enough to make a pin, or a nail, but exhausts itself in making the point of a pin or the head of a nail.”
—John Ruskin (1819–1900)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
