After one Biab, I will never extract again and decided to 3 vessel is the only way. Compact due to garage size and didn't want the stand to take up too much room. My research led me to the MT over the HLT in large units, so why not adapt to a smaller scale. Not sure what to name it, but fun to build. Hlt on the bottom, built in burnner to the stand and temp control / 3 wire gas valve need to finish. The lower bung was so hard to see and reach with the tig torch. The MT false bottom will hinge on the right side to dump the spent grain. 120v electric heater to maintain temp when recirculation.... I'll post more as I continue on. Cheers.
