I've built several Siler percussion locks without any problems and am now in the proccess of learning flint tuneing. After getting the frizzen heat treated on my small Siler Friday all the mechanics seem to work great and she throws some pretty good sparks. The only thing is most of those sparks look like they are hitting ahead of the flash pan towards the frizzen screw. Will bending the hammer change this? Undestand that I haven't tried to set off any prime with her yet and don't plan to make any changes till the rifle is finished. Am I worrying about a non problem? Any advice would be appreciated.
