How to Make and Shoot a Crossbow
From an oak or other hardwood board, 1 inch thick, 8 inches wide and 3 feet long, cut out a stock and barrel as shown at A in Fig. 8. Measure off 12 inches from the end of the stock and cut out a slot with a chisel inch wide and 3 inches long clear through from the top to the bottom. Now with a ½ inch round chisel starting at the end of the barrel cut a deep groove for the arrow to rest in, and then cut a notch in the end of the barrel for the bow.
The trigger can be made of wood, but brass is better. Get a 3/8 inch piece of square brass rod and cut off a piece for the lock (see B, Fig. 8), 2 1/2 inches long, make two notches in it as shown in the cut and drill a 1/8 -inch hole in the lower end; cut off another piece for the trigger 3 inches long and drill a 1/8-inch hole 1 inch from the top end. Set these pieces in the slot of the gunstock exactly as shown at B, drive a nail through the stock and the hole in the lock and another one through the stock and the trigger to serve as pivots, and cut the ends off close up to the stock.
The action of the lock is this: when the string is pulled back and caught in the notch of the lock it has of course a tendency to pull the lock forward but it is prevented from so doing by the end of the trigger which is thrown over into the notch.
When the trigger is pulled the upper end slips out of the notch, the bowstring pulls the lock forward and out of the way when the string hits the arrow, carries it with great force along the groove in the barrel, and shoots it into the air.
To shoot the crossbow set the trigger and lock, and put an arrow into the groove; rest the stock firmly against your shoulder and sighting along the arrow pull the trigger.
