Hi there,
I am making make first steps engraving typographic punches. If you don't know about it is the traditional technique to design letterform for movable types. A letter is cut on the face of a steel punch with files and gravers (mostly used for the letter's counters).
My problem is I am new to working with gravers and I've frequently made them to lose their hardness when forming then with my bench grinder (even using very short touches).
To work on typographic punches I need to form my gravers in a way probably already familiar to you (see image below), taking away a section of the graver's back (in red in my image)
But when using a dry grinder for it, the smallest gravers get cherry-red very easily and if I use a wet stone sharpener (similar to the Tormek) the speed of the wheel is too slow and take ages to erode well the back of the graver.
So can you give me some advice on how to properly prepare my gravers and what tools to use for this task?
Thanks in advance.
