I decided to eat the hen last night, and made some stuffing from the chicken livers. It was real tasty. My wife loved it! I wasn’t sure what to do with the crawdad so I hung it on the front of the muffle furnace for good luck.
I used a candy thermometer to check the temp., of the canola, 120-130.
I checked the outside of the steel muffle for non magnetic, the curie point, 1414, with a magnet, while taking note of where it was at in the color spectrum on the inside of the muffle. The color inside the muffle is higher on the spectrum than the outside because of ambient light. Then, I brought it up a hair, 50-100 degrees, targeting 1475-1500,… a “salmon” color inside the muffle.
Just before I put the blade in, I inserted a piece of cedar wood to create a reducing atmosphere inside the muffle, making sure it was well lit before sliding it to the back of the muffle.
Next, I let the blade come up to temp., same color as the inside of the muffle, and soaked it for 8 minutes. Then I quenched it.
It took a slight warp towards the point so I over corrected it to the same degree in the other direction and brought it back to center with this bending jig.
I checked it with a file just to make sure it was converting to martensite, (interrupted quench) and got it into the tempering oven while it was still about 200 degrees. It’s in the first temper right now at 450 for 1 hour. I’ll do a second temper the same, after it cools to room temp and has a chance to set up. After the second temper, I’ll test the blade and see… So far it seems fine. I'm not expecting any serious problems, since I've done this many a times before... never hurts to test it though.
