I need to bend some round and half round files to use a rifflers. Can
anyone point me in the direction of a website that gives the details of
re-tempering the files after I've bent them. If I'm not mistaken the
process involves getting the file red hot and then quenching in oil. Then
bringing the file up to a specific temperature and or color for a sustained
period of time, and then quenching or letting it cool slowly, but I'm not
sure which.

You might want to try this question over on rec.crafts.metalworking.
