All - Thanks for the well-informed help. No, I've never greased the spindle. I always figured that the crank arms are one of the few parts on a bike that rely heavily on friction to stay in place, so the thought of greasing 'em up never really occurred to me. Given that I've put about a thousand miles on this crankset and the problem is only now manifesting itself, I'm inclined to agree with Joe that the problem stems from the first time it came loose and I simply rounded off the spindle hole. I'll try another arm and see if that helps; as this is my main commuter, bike I'm not inclined to experiment too much for fear that things will come apart half way to work. All the best, Kevin
