To make grape shot, we must have a bag of ticking, in which the small balls are arranged; also a shoe, to which not only the bag which contains the ball is attached, but also the serge filled with powder.
The shoe is made of the same wood with the ball cartridges, and of the following dimensions, viz. The sixteen pounder should have 4.97 inches diameter; the twelve pounders, 4.35; the eight pounders, 3.82; and the four pounders, 3.1 inches diameter. Those of the caliber of sixteen and twelve, should be 1.6 inches in thickness, with a groove in the middle of .44 parts of an inch in depth, and the same in width; the eight and four pounders have but 1.07 inch in thickness, with a groove in the middle of .36 parts of an inch in depth and width. Every shoe or base, has a pin in its centre, the size of which is in proportion to the vacancy left by the small balls of iron arranged about it. The height is in proportion to the different layers of ball.—In general thirty-six balls are put into one grape shot, of whatever caliber it be; that is to say, six heights of six each. The balls should be proportioned to the caliber, so that the six balls on the base should exactly fill the circumference of it. The pin in the middle of the base is exactly the size of the ball and seven times its diameter in height. At the top of the pin a groove is made to tie the threads, the width of which is one-third, and the depth, one-fourth of its diameter.
The bag in which the small balls are arranged, layer upon layer, should be of good strong ticking closely woven. It is of the size of the shot, and 2.13 inches in length above the top of the pin. It is strongly fastened at the bottom in the groove of the base with strong pack-thread. There must be 31/2 fathom of strong pack-thread trebled, to tie the grape of the caliber of sixteen and twelve pounders, and three fathom only for one of eight and four.
Grape shot may be corded in the same manner as the carcase is corded; with this difference, instead of eight turns, taking only six. The best and strongest method of tying the thread in grape-shot, is in the net-work form—one person holding, and another tying it.
In a work-shop where ten men are employed, eight are employed to wind the thread round, and two to attach the bag to the base or shoe, or to arrange the small balls on the shoe, round the pin. Such a work-shop, in a day of ten hours, can complete 120 grape-shot of the largest caliber, and as many as 140 of eight or four pounders might be made.
The grape shot composed of 36 iron balls, weigh, without their charge of powder, as follows:
