I've taken my ku motorized Fortec 80cm dish off of the chimney and am going to give it and one of my coolsat 5000's to my nephew. He's only interesting in Thailand tv. There's 6 channels of it on 97w, so it'll be a fixed system. He works for a chip processor company and talks daily to folks over there and is in the process of learning the language. I now have my 10ft bud working and am tracking 55.5w to 137w on it (very happy with it and my recently purchased Visionsat iv200 and my new Gbox) and other than digging a trench for the cables, and dressing it up a little, I'm just about finished with it. I want to keep ku on a smaller dish, So now I'm working on motorizing my 84e primestar with a sg2100 motor that has a 42mm tube and will be mounted on a pole close to the big dish. I've read a lot of threads and have found the reading helpful. Some of you used pvc inserts and one that I remember from a while back, used radiator hose for a insert. I'm not worried about ruining the motor with the weight of the primestar, so that won't be a issue and for now I'm planning using the stock mount. I've inverted the mount on the dish and have tried pvc for inserts, but still had too much play. Today I picked up a radiator hose and tried it. But it gives too much and has too much spring to it. Did you folks that made this work have the larger tube? Should I order a 50mm tube (a hair less than 2 inch diameter) or should the 42mm tube work? Open for ideas!
