[TowerTalk] TowerTalk] The ultimate one tower system? / Swing gate

[n4kg@juno.com]

N4AR went one step further on a 10 / 15M stack.

He built a housing to support a thrust bearing and Tailtwister
rotor at ground level.  He then stacked galvanized pipe along
side the R45 tower, spaced and supported by angle iron? braces
attached to two tower legs.  U-bolts were loosely placed around 
the rotating mast by putting nuts on each side of the brace
creating a small gap to allow the mast to rotate.  (Aluminum
channel could also be used to the bracing).
