Drilling Hole in Brew Pot
Adding weldless fittings to a brew pot be it a boil kettle, hot liquor tank or a mash tun can make brew day much easier. After I noticed how much the typical homebrew shop charged for a hole in a pot, I took particular interest in doing it on my own. Here is a basic guide to drilling a hole in a brew pot.
Gather Necessary Equipment
Measure and Punch
First measure out where you want to put the hole, you can use the pot handles for reference if need be. Once you find the location use a hole punch and a hammer to dent the pot to keep the drill bit from slipping.
Drilling the Pilot hole
Drill the pilot hole with a small sized metal drill bit. This is used as a guide for the larger step bit, without it things could get dangerous.
Drilling the Hole
Using the step bit, drill the hole to the appropriate size to fit the weldless fittings. Drill slowly step by step and do not apply excessive force.
Smoothing Things Out and Assemble
Use a metal file to smooth down the inside of the hole and remove any hanging burrs.
Assemble the weldless fitting and test for leaks.
