final coat; otherwise the pieces will be held weakly, 

 if at all. Beginners are inclined to use too large a 

 quantity, and this tendency should be avoided. 



In some cases nails are used together 

 with the glue, as at the corners of pic- 

 ture frames. It is customary in this 

 instance to nail in only one direction, 

 as shown in Fig. 53. 



25. Nails. The nails in common use 

 are of two kinds, cat and wire. 



Two views of a cut nail are shown in Fig. 54, a being 

 tlio side view and b the front view. Notice that in the 

 front view the sides converge like a wedge, 

 while in the side view they are parallel. 

 Care must always be taken that the 

 point does not enter the wood as shown 

 at c, as the wood will be split by the 

 wedge action; d shows the proper method. 

 Steel wire nails are now in general use. 

 They are made from wire and are conse- 

 quently round in section, with a compara- 

 tively sharp point. There are two distinct 

 kinds, named flat head and bung head. 

 Flat-head wire nails, as the name implies, have thin, 

 flat heads, which prevent the nail from being driven 

 beneath the surface.
