I don't have any photos, but once you get in there with a small, round Swiss pattern file taking off the knife edge of material at the web formed by the crank arm and the spider, it will be obvious what kind of shape you need, to make the transition as "soft" a compound shape as possible.

Don't forget to polish out all the file marks as they are stress risers and can propagate cracks.
