Hello All,
Back in high school industrial arts - metalwork, some projects involved heating metal up to red hot and then dipping the ends of newly made tools into a tin of case-hardening compound. Just wondering what the stuff was and whether it is still available today?
Since the time era was the late 1970s the stuff is probably banned.
I want to harden the bevelled edges of a beehive knife that I use for separating sheetmetal after I have drilled out the spot welds. My next option is to copy the shape onto a section of old leaf spring.
The shape and thickness of the beehive knife is perfect for getting between layers of sheetmetal without distorting them too much. The only trouble is that I am using a tool for a purpose it was not actually designed for and the edges chip or slightly burr over. While a quick lick with a file does bring the bevel shape back, I am losing metal each time this maintenance work is done.
Kind regards
Lionel
