268 THE YOUNG FARMER'S MANUAL. 



any desired length to suit the length of mandrel, length of 

 auger, and materials to be bored. It is about three feet wide, 

 and from two to three feet high, to correspond with the 

 stature of the workman who uses it. Fence posts, fence 

 caps, bar posts, or anything else to be bored, are laid on the 

 slide a, to which a strap of leather b is fastened, which strap 

 passes around a pulley-roller c, and then is carried back under 

 the slide a, over another pulley roller, as seen in the end of the 

 frame, and is fastened to a treadle. The slide a has gains in 

 the under side of it, which fit neatly to the top pieces of the 

 frame, so that it can slide back and forth toward the auger. If 

 it does not fit well, and one end is allowed to be moved faster 

 than the other end, a post will not be bored at a right angle. 

 (See BANGING SAWS, paragraph 679.) 



354. The way to lore with it. Place a post on the slide a, 

 and stand at the end of the machine, having hold of the slide 

 with each hand, and when the auger revolves place one foot on 

 the treadle and press downwards with it, and push a little with 

 the hands. As soon as a hole is bored, remove the foot and 

 draw back the slide. "When the stuff to be bored is small, lay 

 some pieces of board on the slide a, in order to adjust the height 

 to correspond with the auger. To bore holes diagonally, nail 

 pieces of board on one end of the slide, to serve as a gauge to 

 hold the material to be bored in a diagonal position. 



355. This machine may be worked by hand, or it may be 

 driven by any kind of horse power. Pullies of various sizes may 

 be placed on the mandrel, and for boring small holes it may re 

 volve as rapidly as the journal of a circular saw. "When large 

 holes say four or more inches in diameter are to be bored, 

 the pulley on the mandrel should be so large that it will revolve 

 about one hundred and twenty times in a minute. One horse 

 turns my auger when boring four-inch holes in hard timber, and 

 the auger revolves about one hundred and thirty times per min- 

 nute. Now, if it were driven by a smaller pulley, that would 

 make it revolve twice as rapidly, it would require two horses to 

 turn it in order to keep boring constantly.
