Beer, not rocket chemistry
Well I am on my way to building the rake I have been discussing. Below is a photo of what I have so far. I took a rack and cut out a section to fit my tun. I have both verticle and horizontal teeth/blades and set them in relation to the axis so that as the rake rotates the verticle teeth track between the half spinning opposite it. The bottom of the rake will hang 4 inches above my manifold and rotate at about 8 rpms. I believe this will improve my extraction rate and assist in mash mixing.
