It's been a while since I sat down and actually did some knife work as I have been working on the 2 x 72" belt grinder. Now that the grinder is done I got back to some heat treating today.
I made a foil pouch from 0.002" 304 stainless steel and add a tiny piece of tissue paper.
Then I fold and crimp the edges to make a seal. Two folds all the way around.
While I am preparing the pouch, the heat treatment oven is warming up. Once it reaches 1050°C, I open the door and quickly slip the pouch in.
This is the product after tempering is complete. It's unfortunate I cannot keep the cool colours. They will be sanded off in the next step.
