    Heat treating 440C looking for info

    Point taken. But that would be another very good reason to move it back so the handle is where it gets supported. I could if need be use something to hold the rack down with. I have already widened the slot in anticipation of that exact problem. Still need to make it thinner however. Thanx for...

    Heat treating 440C looking for info

    Ok I now know what the melting was .......... It was not melting, however it did loose metal on both sides of the blade. I used a piece of fire brick with slots cut in it to support the blade. I am guessing that while in the oven the brick heated up and pulled more carbon out of the steel ...

    Heat treating 440C looking for info

    I will go out and grind on this thing some more to see if what I thought was melting was actually melting. Hot and cold spots ? I seriously doubt it. I have a double row of coils running down both sides. There may be a small cold spot up towards the door, since that is the only place unsealed...

    Heat treating 440C looking for info

    I have no idea how to verify 1900 degrees. I have however verified the thermocouple is accurate at ambient temp. How would I verify 1500 or 1900 ? I do have another thermocouple .......... But it would be difficult to change it out. The controller is digital ..... info in output out

    Heat treating 440C looking for info

    Doug, I am done with this knife, I totally ruined it beyond any kind of salvage. It is warped and twisted, the metal appears to have started to melt actually. I did put it on the belt grinder just to see if it had retained anything like the finish I put on it before hand, and that is where I...

    Heat treating 440C looking for info

    This worked well the last time, so lets see if it does again. I am sure this question has been asked and answered here before. Anyway here goes. I got a piece of 440C free from New Jersey Steel Baron, and ground out a knife. Everything is good, till I got to heat treating. I am sure this is my...

    Newbie Question

    Lets see how this works ........... I am fairly new to making blades, I have been putting handles on blanks for a while. The main question I have right now is how thick do I leave the blade for heat treating ?? I have looked on line and nobody mentions how much to leave BEFORE heat treating. I...
