Thought I'd pass along a newbie mistake that I made while putting together a Bedford Rifle kit from TOW parts. After successfully putting together two percussion rifles, I started on a longrifle with an L&R Bedford flintlock. Not realizing that there is a stop surface on the arm of the cock that is supposed to hit on the bolster to stop the cock from going too far, I filed off the stop ridge so it wouldn't hit on the lock mortice. :youcrazy: Oops. After reading another post on this board, I realized that the stop ridge was there for a reason. There is still enough of the ridge to stop the cock from traveling too far, but not much. I can see that it is cutting into the surface of the lock plate already. I guess I'll be ordering another cock arm. :shake: After examining another flintlock, I realize that I need to cut a groove in the upper part of the lock mortice to make room for the stop shelf. This wasn't shown on the blueprints that I bought from TOW as they only show the percussion version. I guess this is why you don't try out your skills for the first time on extra fancy wood. I think this is what you call a "learning moment".
