THE FARM SHOP

Figure 45. Nail Set. On all wooden surfaces to be painted nails 

 should be carefuly driven with a round peen nail hammer and the 

 heads sunk about one-eighth of an inch deep with a nail set.. The 

 holes may then be filled with putty and covered smoothly with paint. 



Figure 46. Cold-Chisel. There are more flat cold-chisels than 

 all other shapes. They are easily made in the farm shop and it is 

 good practice. They are usually made from octagon steel. Differ- 

 ent sizes are needed according to the work in hand. A piece of %" 

 steel 6" long makes a handy cold-chisel for repair work. 



Figure 47. Cape Cold-Chisel. It may be tapered both ways or one 

 way to a cutting edge, or one edge may be rounded. 



Figure 48. (1) Tinner's Punch. Made of octagon steel in sizes 

 to fit the rivets. The cutting end is flat and has sharp edges made 

 by roll filing. It should be about 1" long and from %" to %" in 

 diameter, according to the size of rivet and thickness of sheet metal 

 to be punched. (2) Prick Punch. Usually made rather short and 

 stocky. It may be %" or %" diameter and 4%" to 5" long. (3) 

 Hot-Iron Punch.' Made in many sizes and lengths. The taper 

 should be the same as the drawing.
