I am in the process of converting my Kegs to Keggles and have been wondering where people have been drilling their holes in the Kegs. Where do people drill there holes for the ball valve and their electric elements? I think that I want to put the holes 180 degrees apart from one another and 1/2 way between the handles. How far from the bottom of the Keg should the hole be? I looked around for dimensions for the hole but have not found anything. Any help would be greatly appreciated.
