so today i decided to build the ice cube 60 qt mash tun with copper false bottom and a homemade copper auto sparge. Added a nice digital thermometer and everything came out pretty good. Did some test runs with hot water and everything is sealed and working perfectly.
copper false bottom 1/2"
Those slots in the manifold look wide. Seems like a lot of grain is going to go through. I thought the holes for the sparg manifole shoud be in the up side that way it fills the pipe up then trickles out.
