One thing is not clear to me though - did you use ONLY the caulking / silicon to attach and seal the collar to the freezer? No screws / glue / anything else at all?
I realize the danger of piercing the outer shell of the freezer due to the lines that may run below the skin, but isn't the caulk / silicone kind of flimsy to hold the whole collar on? I ask because I really want to emulate what you have done so far - that's just awesome - but I don't want to have to recaulk in 6 months if not necessary, nor do I want to worry about someone bumping into the keezer and breaking the silicone seal.
Only silicone sealant. I see how it could seems a little unstable, but having read quite a bit myself on this site about other projects, this is apparently the way things are done. It is quite sturdy. The outside of the collar is 1 x 10, but it's doubled up in many places, including the connection with the freezer rim. I used quite a bit of silicone in the join, a thick zigzag around the whole thing. Then, as nathan suggests, I did beads of the sealant along every seam and corner on the inside. It would definitely take a huge bump to dislodge it -- think defensive lineman hitting a tackling dummy. I put the whole thing onto a piece of plywood with casters on it and would definitely be comfortable grabbing the collar to roll the thing around.
The only further steps I have planned are to put some moulding around the bottom -- attached to the plywood base -- so that it looks like it's sitting on the floor instead of on a piece of plywood with wheels. I may also put some more moulding on the corners and possibly horizontally along the seam between the collar and the freezer body and the collar and the lid -- to hide my questionable carpentry.
Thanks for the kind words everyone. I did not originally plan on having a five tap setup. I wanted to get something with at least three or that would be expandable to three at some point. I spent weeks scouring craigslist for a used kegerator that fit the bill, but no luck When it finally got to the point where I had two batches that needed to be put up, I opted for the buildout. When I picked up the used freezer I was still thinking only three taps and room for lagering and chilling, but then I realized that with a tall collar I could get five cornies in there and that was that.
