The idea goes like this: Couple together, inside the tower, enough lengths of tube-not-pipe to extend 10-15 feet above the tower top-plate. Set the tube assembly on a vertical thrust bearing. Center/restrain the tube in the tower, at several points along its height, with shelves and bearings. Guy the tube only, through the tower Z-bracing, as if the tube were going to be standing alone, with horizontal thrust bearings at the guy-attachment points, so the tube can rotate. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
