io8 BEEHIVES AND BEE KEEPERS' APPLIANCES. 



are to be bevelled off and hollows cut to take the 

 heads of the rivets in H (Fig. 95). 



The boards of the bellows can be made of any 

 tough and thoroughly seasoned wood. Two pieces 

 for the cheeks of the bellows are 5 in. by 5i in., 

 two other pieces x (Fig. 95) are 4j in. by \ in., 

 \ in. thick at the back and rather more at the 

 front, so that when the backs of the two boards 

 are brought together the front joint will not 

 open. The piece Y is f in. square and 2| in. long, 

 and another piece is T 3 g- in. square and 3j in. long. 

 The wood piece for the valve is 2 in. square and 

 \ in. or so thick. When all the pieces have been 

 nicely planed and rubbed on a sheet of glasspaper, 

 bore a hole for the valve in one bellows board 

 and one at w for the blast pipe in the other. The 

 latter is | in. in diameter, and f in. from the back 

 end of the board ; the former is \\ in. in diameter, 

 and its centre is 2 in. from the back end of the 

 board. The burrs which may have been formed 

 in the boring of these holes should be carefully 

 glasspapered off. The pieces x should then be 

 glued and tacked across the front edges of the 

 boards, and the piece Y similarly fixed on the 

 lower one, f in. behind x, its ends being equidis- 

 tant from the edges of the board. 



The springs (Fig. 100) must next be made ; each 

 is a piece of wire bent into two parts, and as 

 there are two springs there will be, in effect, four 

 wires pushing the boards apart. To make the 

 springs, drive a couple of wire nails T 3 in. thick 

 into a piece of wood 6 in. apart. Cut the 16 gauge 

 wire 14 J in. long and straighten it, place it against 

 the wire nails with the ends projecting equally at 

 both sides, and turn the ends round the nails, one 

 to the right and the other to the left. Give two 

 and a quarter turns to each end, which will leave 

 them at right angles to the middle part as in Fig. 

 101. Then bend the middle part at M into a curve 

 so as to bring the coils together and the loose ends
