ok,
the mf didn't even want to give part of my money back. don't know how it works in the rest of the world. but i chked with other metal merchants, and apparently if you ask copper, they ALWAYS assume you mean brass 70/30. whatever
anyway, got myself a 1/4NPT tap, 12mm drill, and tapped in my first hosebarb. i'm gonna use the brass for my top halves and for practicing purposes.
amai amai, drilling in more than 6mm with a cheap bench drill is a real PITA. be warned, stepping up the dia with more than 2mm in a step is next to impossible.
