Fire Starting Instructional Video. Firearms Built and Repaired with Care. Reparing a small cannon firing mechanism. Jim Green, Gunsmith. July 2, 2014. Sometimes I get odd jobs coming into the shop. Recently the oddest project was a request to repair the firing mechanism for a signal cannon mounted on a yacht. Why not? Next, it’s off to the milling machine to align the tap with the tool that I use to keep tension on the head of the tap and to keep everything in alignment. Then I make a firing pin bushing.
