Hey everyone, this past weekend I came into a free (score!) corona style mill and copper coil immersion chiller from a buddy I work with. He had it from an uncle who used to brew, so I have no idea how old these things are.
I tuned up the mill as best I could, taking a dremel to grind off all the rust, and mounted it to a pail, following the "My Ugly Junk - Corona Mill Station" thread here on hbt. Ran a pound of rice, and half a pound of 2 row through to clean it a bit, and seems to do the trick. We'll see how my efficiencies are in the next couple batches.
My question is, is there any way to tell if lead solder has been used on the joints of the coil? It's pretty heavily tarnished/spotted, and I'd like to know if it's worth salvaging.
Is this something I should worry about or just another case of RDWHAHB?
Thanks!
