I need some plans or ideas for a home brew chimney mount. I want to mount a 10 foot pole with a small rotor on the top with a 3 band "spider beam" (about 15 lbs) on top of that. I want it to be something I can take down and put back up easily BY MYSELF. The Chimney is about 2.5' by 2.5' brick with a one brick ridge 1" wide, one brick down from the top. Any ideas???
