ELEVATION FIG.5. 



Cut 6. 



1 foot 8 inches by 2 feet is large enough. In making the frame 

 for the door of the Gurler silo, two 2x4 inch studdings are sawed 

 to the proper length and move sidewise to the desired width. 



These pieces can be used for making the frame for the door. 

 The frame is slightly larger on the inside than the door; and on 

 the outside it is a little smaller. The door being slightly beveled 

 on all four edges will wedge itself very tightly into a frame of 

 this shape. 



Cut 7 shows how the door is beveled and also the shape of 

 the frame.
