Construction of All-Wood Silos. 



The studding of the all-wood round silo need not be 

 larger than 2x4 unless the diameter is to exceed 30 feet, but 

 they should be set as close together as one foot from center 

 to center, as represented in Fig. 201, B. This number of 

 studs is not required for strength but they are needed in 

 order to bring the two layers of lining very close together 

 so as to press the paper closely and prevent air from enter- 

 ing where the paper laps.

I'IG. 204. Showing the construction of the door for the all-wood silo. 

 G is a cross-section of the door resting against the door jamb, which 

 is provided with a gasket of three-ply ruberoid roofing and held 

 In place with four lag bolts and washers, the door opening on the 

 inside. F is a front view of the door made of two layers of four 

 inch or six inch tongued and grooved flooring with a layer of three- 

 ply acid and water proof P. & B. paper between. 



To stay the studding a post should be set in the ground 

 in the center of the silo long enough to reach about 5 feet 

 above the sill and to this stays may be nailed to hold in 

 place the alternate studs until the lower 5 feet of outside
