Howdy, I am New to the forum but not new to blacksmithing. I am a full time farrier. One of my horseshoeing clients asked if I could make him some small railroad spikes to use on his live steam railroad. He uses mine rail, I think it is 20 pound rail. The spikes would be made from 3/8" square bar. They need to be about 3" long. I am having trouble figuring out how to forge the head. Has anyone done this type of thing before? Any ideas on how to proceed.?
