plate, and then cut out with a pair of snips. The 

 straight edges should be turned over for \ in., one 

 up and the other down, and the piece bent into 

 the shape of a funnel. The parts turned over will 

 then catch into one another, and should have a 

 little solder run along them after they have been 

 hammered tightly together. The wide end of the 

 funnel, for the distance of \ in., is now to be 

 turned straight out so as to take the bottom (Fig. 

 106), which is attached to it just as a tinman fines 

 a bottom to a can, except that after it is turned 

 over once it is left standing out from the funnel, 

 as seen in Fig. 104. 



Before the bottom is fastened, it would be as

well to make the tinplate diaphragm (Fig. 107) and 

 fix it to the funnel. It is 2^ in. in diameter, and 

 is punched with a number of \ in. holes. In bought 

 smokers it is fitted in a kind of bead moulded on 

 the funnel ; but in the present case three or four 

 projecting tongues are left, and these are turned 

 over and fastened to the funnel with small rivets. 

 The bottom with its fire door cut out is shown 

 by Fig. 106. The outer dotted line in this figure 

 shows the part which will be turned over to em- 

 brace the funnel end. The door is a piece of tin- 

 plate large enough to cover the hole and to pivot 

 on the rivet shown in Fig. 103. Its edges are 

 turned over so as not to cut or scratch the hand 

 of the operator.
