Life is busy, so some catching up is in order. Can't stay up too much later so I'll try to get part of the progress done first.
Fan was placed into thrust/fan tube, and since it is slightly tapered, I sanded a paper thin piece of foam to help center the front of the shroud. A bit of silicone was used as glue. Finally the fan is installed and it shold be in to stay unless some day surgery is needed for repairs, or retirement of the airframe.
