Click to enlarge I modeled this after a Subtank Mini V2 deck. I drilled the juice holes 1/8" in diameter and lined up the bottom of the holes with the bottom of the deck which is 4mm from the bottom of the barrel. It clears the threads inside the barrel by about 1mm. Unscrew the chimney and look down inside the barrel while it is completely screwed down to the deck. I put masking tape on the barrel then marked where the hole would line up with the juice channel (4mm up from the barrel bottom). Leave the tape on so your drill bit doesn't wander. I don't own a drill press so I had to shove a dowel inside, punch start it and use my rotary tool with a pointed grinder to make a divot for my drill. After that, it was smooth sailing and no more dry hits.
