No previous thread, really. I apologize for the rather disjointed thread. I'm trying to piece things together as I go along.

I was quoting a comment I added to iab's Chicago vintage ride thread. A discussion of the crank arm problem didn't seem appropriate there, so I started a new thread. I've taken no pictures of the crank or spindle. The bottom bracket is a Phil Wood. The spindle seems visually to be in fine shape. I got the bottom bracket from a bike I bought for its parts. It was connected to a Campy crank, so I assumed (perhaps incorrectly?) that it has ISO tapers. In my experience, you can't judge the condition of the tapers on a crank from a picture.

I was really just asking what my possible problems are. I'm using vintage parts which I hadn't previously used myself. I haven't experienced this problem before, and I've put together a number of bikes using used Campy cranks and bottom brackets. The new bit here for me is the Phil bottom bracket.
