				|  | Sources of Error Using an Angle Block |  |  | 
			
				|  | WHEN USING AN INDICATOR:
Consider a 45° angle block with a surface of 1" x 2". |  |  | 
			
				|  |  |  |  | 
			
				|  | WRINGING:
 |  |  | 
			
				| Angle gage blocks must be wrung with their sides parallel to each other.  
Else, as seen above, it is impossible to set a true angle. |  |  | 
			
				|  |  |  | 
			
				| It is recommended that the sides of the angle blocks be made parallel by
aligning them against a flat surface after wringing them together. |  |  |
