When evaluating these Rank column I come from a word scrap. After the first assembly of the column, I realized that the column did not look as shown in the picture, but wrong and crooked. Did they then disassembled to investigate the cause. For craft enthusiasts with a lot of patience here for detailed instructions: The reason was that the 12 semi-circular arches of different lengths. For me, from 26.5 to 28 cm. This run the Vertikalkalrohre oblique or zigzag. One must now measure the 12 arches. It should have at least 3 pieces of the same length, place them in the draw and 3 ring levels just above the other. One can put a ring of different lengths together, the rings should however be all the same. If the number of a length of pipe bends is not divisible by 3, it is not just.
