so im wanting to build a few wood chisels to use for inletting stocks and other small wood working projects. I was thinking i could start off with maybe 1/8", 1/4", 3/8", 1/2" in both flat and gouges. i was thinking i would make them out of a good tool steel like A2 then heat treat them however i need to. The flat chisels would be easy. find stock close to the right size and file, mill, grind, etc to shape and sharpen and polish. the gouges i was thinking i could mill the inside curvature with a ball end mill of what ever size. then file or grind the outside then polish. I would be interested in any thoughts or opinions on steel to use, sizes and shapes that are most used in building muzzleloaders, and any heat treating processes.
