Rows Shot: In the shot put a heavy metal sphere is propelled from a circle seven feet in diameter; four feet of its circumference—in the forepart of the circle—contains a toeboard four inches high. In this event the shot is not allowed to pass behind or below the shoulder, so that technically it is "put" rather than "thrown." A 16-pound shot is used in major masculine competition, such as in the Olympic Games, national championships, and intercollegiate competition; the 12-pound shot is usually used by males in secondary schools, and the 8-pound shot is used in feminine competition, including the Olympic Games. In the games the shot put is also one of the 10 decathlon events for men. A put of over 65 feet has been made with the 16-pound shot, and a woman has exceeded 56 feet with the 8-pound shot.
You'll want to make a number of grab shots just before the ceremony . . . bridegroom and best man at their posts, bride on the arm of her father, bride and her attendants as they start down the aisle and at least one long shot during the ceremony. This one shot might well be a long shot of the entire assembly, taken from the back of the church by time exposure, with the Camera on a tripod.
In general, pneumatic wagon drills of the piston type are used where faces are less than 30 feet high or for drilling benches of that height or less. Detachable bits are in common use and hole diameters are from one to four inches. Sectionalized hollow drill steel permits drilling deeper holes. Hole spacings range, typically, from four by four feet up to six by six feet or more. The holes may be fired as a single row or there may be two, three, or four rows shot in a single blast. |
