CHAPTER XVIII 



Sharpening Chilled Shares 



/^HILLED shares are made in moulds the same as 

 ^^ chilled mouldboards. On account of the nature of 

 the iron they cannot be heated and drawn out by pound- 

 ing as can steel shares. When it becomes necessary to 

 sharpen chilled shares they must be ground on the 

 upper side on an emery wheel or grindstone until a 

 bevel edge appears.
