Well I finally got sick of using a ghetto gravity system. It basically consisted of mash tun on top of patio table---->boil kettle on burner---->to CFC on steps to fermenter. I had been looking all over for weeks at designs and what I want, I bought 48 feet of 2x2 steel tubing for the structure. I finally settled on JonW's build as far as the frame goes. So I cut all my pieces yesterday and started to tack the top section together. After tacking I realized why I hated using flux core wire. So I will be buying a bottle of c25 later in the week. Here is my progress so far.
