The tip-up, used for signaling the fisherman when a fish is caught, is made of a 1/4-in. pine board, about 15 in. long, 2-1/2 in. wide at one end and narrowing down to about 1 in at the other. At a point 6 in. from the smaller end, the board should be cut slightly wider and a 1/2-in. hole bored through it. Two or three wrappings of fine copper wire may be wound around the board on each side of the hole to give added strength. Both ends of the board should be notched deeply.
A long gash is cut in the ice and then a round hole is made with a chisel, as this will cut under the water without splashing. The chipped ice can be removed with a pail. A rod or round stick of wood is passed through the hole in the tip-up and placed across the round hole, as shown in the illustration.
Tip-Up in Place
The fishhook is baited in the usual way and hung on a line from the short end of the tip-up. When a fish is hooked, the other end will tip up and signal the fisherman. Any number of holes can be cut in the ice and a tip-up used in each, thus enabling one person to take care of as many lines.
