This is the perfect oven for making knives `n tools | DIY hardening furnace with control | test run

In the future I will devote myself more to making high quality Japanese inspired chef's knives. For this I need the possibility to heat treat longer knife steels. Heat treatment in the charcoal or gas forge is possible, but too imprecise for me. In the video, a "mobile, electrically operated and temperature-controlled heat treatment station for hardening and tempering steel knife blades and tools" is created. Project name: "Here Comes The Sun" or simply: "The Oven"
The furnace is used in knife making for heat treatment - normalizing, hardening, quenching and tempering of knife steels.
The electrical part of the project was appraised by a specialist electrical company and checked by a master electrician before commissioning.
If you have any questions about the construction or the products, please feel free to contact me. The answers could possibly take a little longer because we are moving. I ask for understanding.
As soon as I start making knives and have hardened the first knife blade in this oven, I'll upload a video of it.
