MISCELLANEOUS TOOLS AXD METHODS OF WORK 35 



true in many cases ; but there are certain kinds of work 

 where sandpaper, if properly used, is allowable.

It must always be kej^t in mind that a surface which 

 has been sandpapered has become " gritty," i.e. the fine 

 sand has come off and is more or less imbedded in the 

 wood. Consequently sandpapering must not be done 

 until all tool work has been finished, as the grit will 

 take the edge off the best tool, 

 and the finer the edge the more 

 C[uickly will it be ruined. 



Again, a sandpapered surface 

 is alwaj's a scratched surface, 

 and the finest of scratched sur- 

 faces cannot compare with the 

 perfectly smooth, satiny sur- 

 face produced by a sharp plane. 

 However, there are many places 

 where neither the plane nor 

 spokeshave can be used, and 

 here it is allowable to use sand- 

 paper after the tool work has been carried as far as 

 practicable.
