Forge heat treat on cpm d2.

An update for you guys. I put a good bit of money, and a ton of work into it, and built my own heat treat kiln. I used a lot of red beard ops. Designs, but changed a few things around. I made the inner chamber smaller, it's still long but only about 4x4.5 inches wide. I couldn't put as much insulation on the sides, because of the width of the angle iron I used to make the frame, and the amount I had to work with. That's the main thing I would change if i could.

I had to use 110 volts, and I could only find 18 way kanthal, so I decided running two coils in parallel would be my best bet. Used an auber pid. The one that has the ramp function. So if I really wanted to I could anneal.

I managed to get it up to 1950 to heat treat my 10v knives. I plate quenched in my modified woodworking vise, that I cool before with dry ice. Then got the knives into a dry ice slurry as quickly as I could following that.

I'm currently working on them now. One I ground mostly before hardening. The other I only profiled before. To see which I will prefer in the future.

Good Job Man, proud of you.

Yeah. Posting pictures to here directly just isn't working for me (I'm on my phone). This forum is so similar to the layout of kitchen knife forums, I wish they would just use the same method of posting media as they do too. It's much easier (at least on mobile)

Here's a quick reddit post I made though. I threw in a picture of the 10v knife I've finished too.
