I spent a good while trying to figure outhow to blue steel half decently and finally got there.
I used birchwood perma blue.
I'll post some pics soon.
I recently figured out a perfect way to make picks down to an accuracy of .0001" for all of you who are not machinists there happens to be a machine called an EDM and a wire EDM. I'm lucky enough to have on at work.
Think of a wire EDM as the worlds most acurate computer controlled bandsaw and the blade is .01" wide and can cut in 360 degrees. I have about 9 feet of scrap bandsaw blade and 6 hacksaw blades and just relized how perfect the machine would be for picks. I'll post a report after some attempts.
