I used a 4" c-clamp to bend the rim in slightly. Folded a strip of cardboard into a "U" 10-12 plies thick to protect the pot. Put the cardboard over the rim, the c-clamp over the cardboard, cranked it down, loosened it up, moved it ~3/4", clamped it down again... Repeated all around the pot.
Viewed from the bottom the gap between the rim & pot was about 3/16". I cranked the c-clamp down until the rim touched the pot; when I removed the clamp it sprung back to a ~1/16" gap.
Note: the rolled rim is stronger than the single-thickness pot wall, so it bent the top of the pot OUT as least as much as it bent the rim IN -- but the lid fits perfectly now.
