The problem is the heat increases the amount of lead dissolving in the
brew. I remember as a kid in the early 50's my father explicitly
telling me do not use the hot tap water for anything you eat or drink.

I'm making a wort chiller. That's just a spiral of copper tubing to cool
boiling hot beer brew to put into the fermenter. I need to join the ends,

than a compression. Is there any problem with that small amount of solder
regarding lead?
