I use a retangle cooler to mash my grains. I was thinking of buying a piece of 3/8 thick plexglass and cut to fit the inside of the cooler. If i used some wooden dowels to keep the glass just higher then the drian tube, and drill a sh*tload of 1/8 holes would this work. I am looking for something much easier to clean, then the current screen method. This appears to be a cheap and easy fix for a false bottom.
