Reviewing the pictures again I see some of the pictures show signs of rust on the male tapered shaft. The rust tends to further support that opinions that the male and female tapers did not have the correct fit. The picture with the key in place also shows signs of rust. Thus allowing the hub to flex slightly on the shaft.

If there is a lesson to be learned from this post, one should ensure that the wheel hub and tapered shaft are very clean and free of any lubricants. While not very experienced in this type of wheel fitment, I would guess that when gently sliding the drum on the shaft without a key as a test of the fit they should mate up with a snug fit. If not, then the reason should be investigated before doing a final installation with the a key.
