Well, I just spent 2 entire days reading this thread. Great info on here. I only have one question before I start my build. The barrel that I have had sodium hyrdroxide beads in it. It is unlined, and there is a little residue left in it. Should I use this barrel or find something different? I looked up what that was and am still not sure if I should use the barrel. Plus I have no idea how to clean it out (heard no to inhale fumes or get on skin, etc..). Although, people have used oven cleaner to try to get liners off which contains sodium hydroxide......
