[TowerTalk] Rotator cage design

I agree with Kurt, adding a bearing plate is the best approach for your
tower. Here is one example: http://www.g0hwc.com/latest_projects.html

I understand that rotators are not designed to handle lateral loads, and
that I should therefore have the rotator on one shelf, then a second shelf
above that with a radial support bearing on it, to handle the lateral
loads. The most likely antenna at the moment (still a moving target)
weighs 29kg, with a 7.2 sq ft wind load and a 6m turning radius. Kurt K7NV
suggested welding two plates on the side of my pole/tower, at the top, a
few feet apart. Does anyone know of existing designs/drawings for that
kind of
thing?
