SHEEP SHEARING SHEDS AND YARDS

general planning and arrangement. The agents for the machine decided 

 upon will attend to the necessary erecting. It is usual, in this country, 

 to have the shearing tubes 6 feet in length ; but, as a consequence, the 

 swing round of the tube in shearing is rather limited, because the height

of the fixed point is too low. Shearing is made easier by having the 

 cores and tubes at least 7 feet long, and fixing the shafting correspondingly 

 higher. 



The bearings for the shafting must be truly lined up, and free from 

 excessive vibration. A particu- 

 larly firm and strong arrangement 

 is that shown in Figs. 204a, b, c, 

 where the brackets, which carry 

 the bearings, are bolted to a 3" 

 by 9" deal crossing, and bolted 

 to, the uprights. 



There should be a fair sized 

 window, about 3 feet by 2 feet 6 

 inches, in front of the lean-to 

 which contains the engine and 

 grinder. This allows of good 

 grinding being accomplished. A good light is necessary, as the combs 

 and cutters are very easily destroyed by careless grinding. The grinder, 

 it will be noticed, is installed close to the engine, away from the 

 shearing: floor.
