If you have decent mechanical skills and like to take things apart and fix them, there's no limit to what you can potentially fix. Add good electronic skills to the list and you can fix even more.

I've kind of started up a new hobby, fixing expensive lenses that are broken. My 14-24mm F/2.8 is one of my repair jobs, and so is my 80-400mm VR lens. These were both lenses that Nikon quoted MORE than a thousand dollars to fix.

I'm not going to tell everybody who knows which end of a screwdriver to use as a prybar that he should start fixing his own lenses, but it's not such a mystery and black art as Nikon would like you to think it is. The mechanisms are precise, but not particularly complicated.

I removed the set screws and there were some thin metal bands, the popped off the posts. It wasnt that easy to get it back together. When the mount arrives I may defer this repair project to someone else more experienced Rocketman 122 ?

Those bands are shims, which are selected for that specific lens to ensure that all the geometry works out. The trick to them is to place them on the lens body first, then carefully lower the mount ring onto them without disturbing their location, and then placing the screws and tightening the screws a little at a time, evenly, in a pattern like you use to tighten down lug nuts. The part will settle into the right position by itself when you do this. Never force anything. Moderate pressure on the parts, and moderate screw torque, is all you ever need. If it doesn't go together properly under moderate force, something is out of position.
