Hi faveral On the pistol example you show the band in the middle goes over the barrel, (helps hold the barrel in place), the metal to the right is an endcap on the wood. I think the hammer should be thicker, a hammer as thin as yours would bend etc too easy. I realize the metal is flat, but it should be thicker. Take a good look at the flint in your example. In any case I'm proably too picky. You do good work.
