here is the start of my electric Hot Liquor Tun for making beer. It is a Target 32 quart Igloo cooler for $19.86. I am adding a 1500 watt hot water heater element, a ball valve for draining into Mash Lauter Tun in which the grains steep in. I am also adding a temp gauge in it to make sure I get it up to temp and as a check that my electric temp control unit is accurate. First I had to cut the handle down as it would protrude with where the ball valve and thermo will be located. I used my chop saw for this. Next I needed to locate a spot where I can safely drill through the cooler at its lowest point but still have room for a big washer inside the cooler and the O ring that seals it. I used a 7/8" hole saw for this. Next I drilled a 3/8' hole for where the bulkhead goes through that holds the thermo . I wanted to also keep this low for small grain bills that dont require much water. I was going to also do the hole for the heating element tonight also until I realized that my holesaw set skipped from 1 1/8" - 1 3/8" which of course I needed 1 1/4"!!!!!!!!!!!!!! Oh well, guess I have to go grab one of those at work tomorrow if we have 1 or back to Home Cheapo! More to follow in the next few days.
