I need to make 2 new firing pins for my Husqvarna Mod. 20 16 gauge SXS as the originals are nearly as sharp as nails on the points and occasionally punch primers. They are simple all round units and should be easy to make. Could anyone tell me what type of rod to use to turn them from as my only tools are sharp files, mic & caliper and a 1/2" drill in a vice for a lathe. I will then harden them but I need to know of an easy machining rod that will "harden" w/heat and quench. Thank you all-Muddy
