Well, we have one of these that had a problem. And, after having three grown men follow these instructions they were not able to get this sight back together. I couldn't stand it anymore - so 'I', the woman of the group, took over the reassembly process. I gave them four days of struggling to figure it out. After truly 'reading the instructions' I was able to reassemble this in less than 15 minutes. The true key is knowing that you have the spring anchored at the 4 o'clock position relative to the 12 o'clock pin position on each of the hubs. Had to share this with you though, I'm proud as punch to have been able to get this done expeditiously after watching these guys working on it for so long!!
