Sharpening files and rasps

There is a few youtube vids showing how to sharpen files and rasps. Has anyone done this? Does it work? I know I can send them to Boggs but I live north of the border and the freight, not to mention custom hassles, make that less than attractive.

OK. I tried it myself and it seems to work. I used Dupont metal conditioner

Which is phosphoric acid and chromic acid. Put it in a piece of 1 1/2" ABS with a cap on the bottom. I cleaned the file with lacquer thinner and then soap and water. Maybe it was just the good cleaning that did it but I don't think so. I'm going to do more files with some kind of before and after test(Yet to be determined)

Keep us posted. I have a couple that could use some "touching up."

I did them for another night. They feel really sharp. Kind of stick to your hand sharp. One had a few aluminum bits stuck to it. I thought the acid would eat that up. It didn't. They have to be clean. More later.

Ed Scott told me he uses Muriatic acid to sharpen his.
I have not tried it myself yet.

I was going to use muriatic but I couldn't find it. That's what I get for cleaning up my shop. So I used the phosphoric and it worked great. I am going to get some muriatic to do the rest of my files. I think it will be a lot faster. Some of my files were my father's and were just tossed in a box for fifty years. Once I get them sharpened I will treat them better. Anyway it's definitely worth doing.
