nects the support H, the hand-guard G, and the 

 little piece M, all together towards the front, while 

 another 1| in. from the back holds H and G to- 

 gether. A | in. hole should now be made in H 

 and G | in. from the back, and the whole may be 

 attached to the barrel with the two rivets shown. 

 The rivet holes are punched. The top of M should 

 be filed hollow to fit the curve of the barrel, the 

 front part of H being hammered to a similar curve. 

 The diaphragm D (Fig. 95) is of sheet iron, and 

 the legs are sometimes riveted on, but it is easier 

 to cut it out of the iron in one piece as in Fig. 97. 

 It should be punched with J in. holes. The 

 diameter is just a little less than 2j in., and the 

 legs are 1 in. long ; they are turned up at right

angles to the body. The leg L (Fig. 95) is riveted 

 on. 



The only difficulty likely to be experienced in 

 the coned blast pipe P (see also Fig 98) is the 

 coning of the mouth to f in. This, however, is 

 easy after cutting two nicks in the piece of \ in. 

 tubing as in Fig. 99. Anneal the brass by heating 

 it in the fire, and when cool, the point can be 

 hammered cone-shape without much trouble. A 

 touch of solder will mend the cut afterwards. This 

 is not a professional method, but is quite good 

 enough for the present purpose. 



The piece of wood s (Fig. 95) bears the whole 

 weight of the tin portion. Oak will be found the 

 best material ; and suitable dimensions are 4| in.
