centers that have been laid off. The scrap board prevents the lumber 

 from slivering. Bore the holes straight into the wood. To aid in 

 boring the holes to the exact depth desired, bore a f inch hole lengthwise 

 through a piece of scrap lumber 1 by 1 by 4 inches, and slip this on 

 the shank of the bit to form a collar ; the bit should extend 2f inches 

 beyond the collar. Bore a trial hole in a piece of scrap lumber with 

 this collar on the bit ; if the hole is too shallow, cut off the end of the 

 collar to get the correct length ; if the hole is too deep, make another 

 collar. After the holes are bored, trim the edges along the side of the 

 piece until each opening is f inch wide. Bore and trim up the holes 

 on the other side of the piece in the same manner. Paint or stain the 

 case ; this will improve its appearance as well as preserve the wood."
