I bought a flintlock pistol a few years ago. I could never get it to spark. I thought I’d have another look at it. I’ve tried different types and shapes of flints, but never once a spark. What I’ve learned is that the problem is either a weak mainspring or the frizzen isn’t made of the right steel. Adding a thin piece of the correct steel to the face of the frizzen is the first thing I think I will try. Can I attach it with JB weld or does it need to be soldered or braised on. What steel do I need to use for best results? All advice is greatly appreciated. Thanks.
