So I was looking for a stainless steel workbench for my garage and I found one on Craigslist with a soda machine attached to it. It was originally from a restaurant and so it was a full setup with an Ice hopper. In order for it to work it needed many bags of ice in the Ice tray to be cold enough for the CO2 to absorb into the water to stay carbonated. I didn’t want to have to purchase ice every time I wanted a soda and so I wanted to build it into a freezer to keep everything cold so it would be ready anytime I wanted a soda. It sat in my garage for a couple of years until I finally had enough time to work on it. There are a lot of DIY kegerator setups that are built the same way so I built a keg into it as well and also used a spare soda pump to add wine to it. To keep it stand-alone I didn’t want to route water to it and so I an using 5 gal bottled water as the water source that I keep cold in the freezer itself. The freezer has a temperature regulator that cuts power to it and maintains it just above freezing. I also added some inverted liquor dispensers with everything needed to make a nice long island ice tea.
I soldered the switch pin directly to the back of the light where the original wire attached. Then I sandwiched the pins of the switch in-between the two halves of the light. I had to notch the plastic a little to get it to close.
