After getting the kettles and the stand build, I thought a little test was in order. We filled the mash tun up with water to see how the dump system would work. It looks promising, but I am going to have to build a step for the front of the mash tun to sit on during operation because it tips forward on its own. Other than that, it is a complete success!
I glued a few extra pieces on the sides to help support the plywood at the top.
