[QUOTE="pjgregory, post: 555202, member: 288654"] Hi Channel Hopper As I mentioned, I did lock all the metal arms togther as tight as I could and only removed the bolts to the fibre pannels. However, transfering the weight onto the arms when the dish is reassembled rather than the other way round in the garage, could cause the arms to bend a little, moving things out of alignment. With the lower petal removed, I can get 3 strings to cross in the center within a 5mm band. I know that I can improved this when the remaining petal is replaced, but then I cannot see the crossing point of the strings. I plan to make a scafolding support on Monday so that I can stand inside the dish. Then I can do the string test correctly. What do you mean by a "boresight" tool? I know that I have to get the axis of the feed horn aligned with the center of the dish. I have ordered a green laser pointer to go inside the tube of the feed horn so I can align the spot with the center. Is this what you mean or is there an alternative method. PJG [/QUOTE]
