Another thing to add to the update:
I spent a lot of time putting hinges on the collar as well as the lid. I thought if I could open the collar it would make it easier to move kegs in and out. It was a waste of my time. I never open the collar. I always open the lid when I move kegs in and out. If I had known, I could have saved the headache of drilling (and re-drilling) trying to get everything to line up
