Can we get a consensus?

How does the brass hold up to the electrolyte? I'm sure it's fine, since you are still doing it, but it's better safe to ask than be sorry down the road.

Brass goes nasty after a while, but I don't use it for the barb, just to cut the thread for the nylon one.

Sweet. Need to remember that one.

I would recommend making a test thread or two first though, you need to heat the barb just enough so that it needs a little effort to turn and cut the thread, if you heat it too much it's just like turning it into butter and difficult to cut straight.
