(E) CUT-OFF SAWS. Cut-off saws are 

 either swing saws, jump saws, or stationary 

 saws with carriage moved by hand or auto- 

 matically, or travelling railway cut-off saws when 

 the saw is moved horizontally against the timber. 



(F) SANDPAPERING. 



1. Belt sandpapering, for carriage spokes, axe 

 handles, table legs, buggy poles, <&c. 



2. Disc sandpapering, notably for boxes. 



3. Spindle sandpapering, for small toll handles. 



4. Swinging post sandpapering. 



5. Cylinder drum sandpapering, with two, three, 

 or four "rolls."

(G) SCRAPING. By "scraping" is under- 

 stood the removal of an extremely thin (not 

 over I'm inch) layer of tissue from a planed 

 surface. It is meant to replace and to cheapen 

 the process of sandpapering, and is not intend- 

 ed to reduce the thickness. The scraper con- 

 sists of power driven, smooth feed rolls and of 

 one or two stationary knives, over which the 

 boards are passed. Corky or stringy lumber 

 cannot be scraped. 



(H) MITERING. In mitering the stock is 

 run along the so-called "fence" against a circu- 

 lar saw, the plane of which forms a variable 

 angle with the plane of the saw table.
