Not trying to hijack this thread, but now I'm confused
Do you recommend connecting (with silicone or whatever) the collar to the freezer or the collar to the lid?
I've built a collar but not installed it because it looked to me like I would need to connect the collar to the lid, which looks like a lot of work. So, another clarifying question is; is the answer to the previous question determined by the height of the collar?
I've made a short collar using 1x2 because I just want to run CO2 into the keezer. I'm not running faucets through here. The inspection of the hinges leads me to believe that unless I made a 6" or taller collar that I could not move the hinges up high enough to not require drilling into the freezer (all bad) to mount the hinges. Any collar less than the height of the hing body (currently attached to the freezer, not the lid), would necessitate fastening the collar to the lid. Am I over-analyzing this? I just don't want top screw up a brand new freezer.
