<p>Construction of an aligned wall of building blocks wherein superposed blocks (10, 11) are connected by means of small metal balls (3) in semicircular openings (2) wherein compensation is made for variations in height of the blocks by drilling said openings to a depth which is dependent upon the height of said blocks and wherein compensation is made for face perpendicularity by providing aligned top V grooves (5) in which is placed a reenforcing metal rod (6) so that an aligned row of said blocks can be manipulated until the most optimum face perpendicularity is obtained to result in a tolerance between said balls and the edges of said openings of .001 to .002 of an inch. </p> |
