New equipment - hardening furnace

I want to  will show you some new stuff in my workshop. First of all, I finally have my own hardening furnace! Like almost everything in my workshop, it was build from scratches. This time not my brother build it as it is usually made, but my father. It is a very simple construction with electric heater. PID controller is used for regulating temperature. Chamber is almost 30cm deep so also big knives can be heat treated. It works more than well but there is still a lot of test I have to made. Now I am using it mostly for titanium anodization.

I also bought the famous Tsubosan file set for hardness testing. Will soon make a good use of it so stay tuned:)
