Okay, so I've been searching around for a while to see if anyone has addressed this topic to no avail. I recently got my hands on some 55 Gallon SS Drums from a closed down winery and would like to build a very large system for doing club brews. Unfortunately, these are somewhat on loan so I dont want to destroy them too much. Basically I wanted to convert one to a mash tun and run my pickup tube through the side bung hole, but Im not sure what kind of fittings are appropriate for the situation.
Has anyone worked through this before and found fittings that work through the hole? I might have found one approach already, but would like some confirmation from someone with more expertise too.
