THE OLIVER PLOW BOOK 



A picture of a soft center steel share pounded on the upper side. The 

 edge has the appearance of being somewhat rough but the hard steel was 

 worked down over the edge. Sometimes in heating soft center steel 

 shares the layers of steel are loosened. Wherever this happens pounding 

 the share on the upper side keeps it from wearing away. 



Soft center steel share pounded on the under side when being sharpened. 

 Notice that the hard steel on the surface has been broken away on the 

 edge and on the point. This is caused by improper heating when 

 sharpening and pounding the share on the under side. A little practice 

 in sharpening soft center steel shares in the correct way and an under- 

 standing of how to set them on the plow will eliminate a great deal of the 

 difficulty farmers experience in the operation of the plow. 



After the point has been hammered on the anvil 

 to the proper shape, if necessary, a piece of steel can 

 be welded to the top of the point. 



Care should be taken in doing this work not to dent 

 the share when hammering it out as this would spoil 

 its scouring qualities.
