hello I'm new to this forum, been trolling here and using some of the creative ideas to build some of my brew equipment. I have built a 2 tier simple all electric batch sparge rig utilizing a portable PID control box and 4500w elements in the hlt, mt, and BK. I made all with the ability to plug and unplug from each element so I only need one PID, ssr, and heat sink. I use a lift table instead of a march pump to transfer beer from BK to fermenters. I think I may be able to contribute for those that need piping,welding,brazing,soldering and fabrication advice since I'm a pipe fitter. looking forward to learning from all the knowledge brewers here.
