Need to know what I am doing wrong. I have a propane forge. I am using garage door springs that have been cut into individual coils. I have been shaping them in the forge to a c shaped fire steel. I was told once they were shaped to bring them to a orange heat, and then quench in warm water. If I put them on the grinder, they throw sparks no problem, but if I strike them with a flint, nothing happens. Are the steels too hard? do they need to be tempered instead? Anybody got any hints? larry
