So, I have been focused elsewhere since that post. A buddy of mine wanted to borrow my clamps for a speaker project. I gave them to him today. The kettle bowl has been clamped this whole time.
After 6 - 7 weeks, the kettle bowl is perfectly round again. One I get my clamps back, will finish adjusting the lid.
The bowl was the one that was further off from round than the lid. The lid now sits easily in all directions.
