of the plane will permit the screw to be inserted from 

 within outward i. e., so the head is inside, and the 

 point appears on the exterior of the plane. It will be a 

 close shave at the handle end, but it is possible. Any 

 one who has a lathe will do this for you in five minutes. 



Now construct the following diagram, or as much of it 

 as may be considered 

 necessary to obtain 

 the result indicated 

 hereafter: 



A represents a 1J- 

 inch strip of pine, 

 four feet long ; _Z? 

 your Bailey plane, of 

 which C is the bot- 

 tom and D D the 

 sides; E an equilat- 

 eral triangle, which, 

 since all sides are 

 equal, must also have 

 equal angles of sixty 

 degrees each, and this 

 is the angle you re- 

 quire; F an end sectional view of a block of wood, to be 

 screwed to the side of your plane; and the object of the 

 diagram is to enable you to so set a bevel square, or to so 

 cut a piece of thin sheet metal, as to guide you in ob- 

 taining the angle, 6r, on such a block. 



It is clear that if a piece of bamboo is rigidly confined 

 in the rabbet of the strip, A, and your plane is applied 

 with a block (jP), so formed, attached, that if the bottom, 

 H, of that block rests on your planing board while the 

 plane is actuated, it must produce the proper angle of six- 



Fig. 63.
