I, like many around here, found a chest freezer on Craigslist and converted it to be a kegerator. My last stand up fridge had 5 taps, so I needed to get a freezer that held at least the same number.
I wanted the collar to be a more "finished," so I covered the 2x6 rough pine collar with a cherry-stained 1x6 pine finish boards cut at a mitre. I trimmed out the rest of the collar with pine corner trim and 1/2 in' trim on the inside:
Actually, if I pushed it, this one could hold eight taps, providing I use the 3 gallon ball lock kegs to sit on the compressor hump. Otherwise, I've got room for one more 5 gallon corney.
The CO2 tank is on the outside and feeds two 3-way manifolds. Tubing is secured to the collar via plumbing collars.
Two day project. Easy.
