The entire bar top is secured by screw's underneath and the keezer slides out from the back!
Step 1: It starts with a plan?
I started with a sturdy base. A nice sheet of 3/4" plywood, framed underneath by 2x4"s, with two additional supports directly under where the majority of the load feet would rest. One downside. I didn't realize until too late that I made the base wider than an interior doorway. While it will still fit through a 36" door, I won't be able to get it through bedroom doors if I wanted it to be in a future man-cave.
For the rest of the support beams, I chose 2x3"s in an attempt to save a little mass / total weight. After building the collar for the keezer (to raise the lid height), I was then able to get a better feel for the total height, and how tall the "legs" needed to be.
