The AutoSparge™ can be easily installed into any kettle or cooler larger than 12" in diameter. Blichmann Engineering also offers optional AutoSparge hole punching service for installing the Autosparge™ in your BoilerMaker™ brew kettle! Simply specify the position you'd like below and we'll punch it for a nominal fee.
To install yourself, you'll need to punch / drill a 13/16" hole in your kettle or cooler. A 7/8" hole will work, but it's a little on the big side. We recommend using a step drill or a Greenlee knock-out punch. A great source for these is McMaster-Carr . The step drill is part number 8841A24 (89315A42 for TiN coating) or a punch 3449A999 - requires a 3/8" pilot hole. This particular punch (Greenlee model 730BB) is special-order with a three-day lead time. Slug-Buster types are available in their catalog but do not work well in this application. When drilling stainless steel, a moderate to slow speed is best to avoid overheating the tool. While hole saws will also work, they are difficult to use in stainless sheet metal.
