I'll let you know how I make out, but I'm in the process of refurbishing an old keggerator. The fridge works, the door is a mess, the american sanke works, the tap is toast and the drip-pan is good.
I'll likely fashion a new door out of aluminum plated plywood using styrafoam SM insulation. The seal should be easy to find and I'll pick up the parts from e-bay. Generally a working fridge is the hardest part of peicing something together. Ideally I'd like two taps for two different beers. This means i'll be using stella kegs inside and am going to have to find some european sankes.
