I am about 99% complete with my GrainToGlass clone keezer. Thanks to all for lot's of inspiration, answered questions and great ideas. Thought I would share some photos and what I would do different if there is a next time:
1) I wanted to plumb the two three-regulator Kegco secondaries together with a long nipple. The fittings must be assembled with loctite as they will not budge. So, I'll have to tee off the primary outlet. Don't assume these ganged regulators will come apart!
2) I screwed the 2X6 collar together on a flat surface (table saw) but due to imperfect cuts it pulled to leave a gap of 3/16" in one corner when placed on the freezer. Foam seal took up the gap but if I did it over I would assemble on the freezer and slowly torque the screws insuring it stayed flat.
3) The 1" foam polystyrene board is very soft. So as I lean into the freezer the aluminum foil tape crushes under pressure. I would cut another 1" wide X 3/4" wood strip to protect the top of the foam board, especially on sides and from where I'll be leaning over to load and unload.
Cheers!
