Tried the HSS again. Got about 4 teeth into it before the tip broke off. Perhaps it is just the steel I was trying to harden for the punches. I guess i'll find out when that rebar arrives! |

I still think a cold chisel is the way to go, don't you have one kicking around in the rust and odd bolts, shot VW Beetle condensers, and half bent cotter pins at the bottom of your tool box? Everybody else does. :lol: |

This one was kinda interesting: --- Quote ---To anneal a small piece of tool steel you may need to bury it with a larger piece of steel heated much hotter (an orange). Bury the two pieces next to each other but not quite touching. Test as above. Remember, the 40°F (22°C) per hour is a maximum rate, the slower the anneal the softer the steel (to a point). --- End quote --- |

Have you tried another file as a chisel just let the colors down to dark straw , no need the anneel and reharden . |

I remembered that I have a whole bunch of empty fire extinguishers that'd probably make good holders for the charcoal. Not sure how important insulation is though. I imagine I'll be getting the files hot outside of the fire first. |
