Thanks for your post. Your build out looks beautiful. I really like the idea of adding hinges to the collar. I think this would make transferring full kegs easier to manage given the additional height of the collar. I have one question - you list #12 1/2" wood screws for the collar hinge. I know it's been a while but would you confirm this? #12 are fairly thick screws and I don't see them being made smaller than 3/4". #10 can be found 1/2" in length.
Thanks and cheers!
EDIT: The #10 1/2" screws worked great for attaching the hinges to the backside of the collar.
