Good advice Joe. Especially with fine little Swiss jeweler's files. And ESPECIALLY with aluminum. But you know what I use? Chalk. Stick is about an inch in diameter and four inches long. Meant for filling the teeth in files so they don't load up. Works great.
As for the OP's efforts here, I agree, this is one tough crowd. A little more work cleaning up and these will be nice, Zieleman.
